Warren E. Buffett-Berkshire Hathaway

Dear Barbara:

This is a belated thanks for the terrific service you provided me in the sale of the two units on Broadway.

You evaluated the situation well and provided much informative data in respect to comparables and other matters. Additionally, your communication and service during and after the sale were superb.

My satisfaction score is 100%. Good luck to you.

Ben Bang and Megan MacLean

Thank you so much for your help. You two are so professional, prompt and polished. You made this process so seamless from a seller’s perspective. I can see why Dave McMullen recommended you. We will definitely keep you in mind for future referrals. The difference between you and our previous agent is night and day.

Honorable Mayor Gavin Newsom

If you want top results, Barbara and Robert are the #1 Agents in San Francisco. They sold my place within a short period of time and helped me purchase a new home thereafter. They are highly recommended and work hard to full fill every Seller and Buyers dream as they did for me. I will always work with Barbara and Robert for all my real estate needs! Barbara's assistant David Ayerdi is the best! His professionalism, diligence and integrity are highly regarded!

Victoria and Kelly Brazil

Hi Barbara and Robert,

Thank you so much for helping us find our new home. We found a home that we absolutely love, in record time and within a very competitive market, thanks to your expertise. We felt comfortable with all parts of the process, every step of the way. Your professionalism, communication and attention to detail is unlike any other. We truly appreciate your outstanding service and look forward to working with you again. We are truly grateful for all of your help and highly recommend you both.

Rich Aurilia-San Francisco Giants-Infielder

Working with Barbara was an absolute pleasure. With a limited amount of time to find a place to live, Barbara had numerous places lined up for us to see that fit our needs. Her professionalism, courtesy, and attention to detail is incomparable. She made our transition back to the Bay Area a smooth one.

Robert and Patricia Donnally

Ethan M. Grumbach-08/20/2015

Dear Barbara and Robert,

My brothers and I are extremely pleased to have listed our family home with you. The services we received went far beyond our expectations. The detail and thoroughness of your efforts was dramatic and helped with a very difficult transition. Your clear sense of the market, what prospective buyers would be seeking and how best to present the home were right on target. Facing the task of putting the home on the market for the first time in fifty years was a challenge. Your expertise, advice and clear objectives made the process seamless and efficient.

We were particularly impressed with the vision you created for the house, the explicit attention to detail and the follow through in achieving your goals, which even went beyond the closing date. You both were always available and had strong, clear ideas and suggestions of how to handle the various dilemmas that arise in putting a home on the market. We also appreciate the follow through from David Ayerdi in your office. Together your team really helped get the house on the market and sold in an amazingly short time.

We are grateful for your assistance in helping our family through a transition which resulted in a very positive outcome.

Michael and Dianne Yancey

Dear Barbara and staff,

Michael and I can't thank you enough for the flawless service that you exuded in producing us with a wonderful buyer, (like pure magic) and selling our Telegraph Hill home in a matter of days. What could have been a stressful process, was indeed the exact opposite. It was such a rewarding, painless and worry free experience. Simply put, a true pleasure to do business with the top real estate agent in the city...In addition to your expertise in the field, your genuine kindness, warmth and integrity went way beyond measure.

We are so appreciative and grateful to you and your assistant David. Many special thanks, we'll be sure to recommend your services to friends and associates. McGuire Realty continues to excel in the marketplace due to the hardworking professionals they have on board!!

All the best,

Dianne and Michael Yancey

Ted Hoffman-Alliance Ventures

This story about Barbara Callan is quite revealing. We wanted to sell our beautiful Sea Cliff home and interviewed six different real estate agents for the task - every candidate a top performer from the largest firms in San Francisco. Barbara was selected hands down after thorough interviewing because of her impressive professionalism and sales knowledge, wise insight on how to make minor home improvements for big perceived value, and insight on how to perfectly price the property.

Although there were numerous challenges in preparing the property for sale, and consumating the actual sale, none of which were attributed to Barbara, she was an incredible asset, advisor and team player to our family. Her very positive mindset was consistent throughtout the whole process. She eagerly volunteered to handle every single detail (and there were many), calling on her extensive network of very competent and delightful subcontractors. She made the entire process easy for us - we just trusted her competentcy and advice. She's exceptional - a real professional and a pleasure to work with. We think she's the best!

Jeff Loustau

Dear Robert,

As we are finally settling into our new life, I wanted to take an opportunity to reiterate our tremendous satisfaction with the service of McGuire Real Estate. In choosing to relocate from San Francisco earlier this year we turned to you to help us position and sell our home in a very challenging market. We'd appreciated your excellent service years earlier when we purchased the home but with the economic circumstances so different this year, we called on you to make something extraordinary happen in a very tight timeframe.

Together with your mother Barbara you present a formidable team. We were immediately able to access your extensive network of stagers, inspectors, and gardeners to prepare the home for showing; your marketing people and photographers did an expert job. Everyone we worked with was timely and professional and charged very reasonable rates.

Finally, were it not for your experience in good and bad markets, and your knowledge of San Francisco, I doubt we would have faired nearly as well as we did.

Joseph M. Alioto, Jr. and Erica Galos-Alioto

"As first time homebuyers, we needed an agent who would help us understand the process so we felt comfortable with our decision. But with our busy careers, we needed an agent who would make the process simple and not consume a lot of our time with unnecessary tasks. Barbara was the perfect combination of these things. She made everything clear and easy to understand, and helped us get the first condo we bid on in a very competitive market. We bought the place on terms we were comfortable with and we couldn't be happier with our choice!"

Laurence Pelosi

"Barbara and Bob took on the sale of two units at one of the most challenging times in the market and got both sold within a week above our expected price. It was truly an amazing effort."

Lori Puccinelli Stern and Peter Stern


We can not thank you enough for the amazing experience we had working with you! As first time home-buyers, you made this very daunting process easy, understandable, painless - and extremely enjoyable. The way you guided us through every step was completely reassuring and put our minds at ease through out. And now because of your wonderful dedication to our family and your second to none knowledge of the real estate market - we are living in our dream house! We had always heard you were the best, so I can't tell you what a joy it was to personally experience your flawless expertise. Your were understanding of our jitters and incredibly informative and honest - especially when it came to our million and one questions. Having you spearhead the biggest financial investment and commitment we have ever made, certainly was a no brainer. It goes without saying that we will never work with any other real estate professional. That said, the many friends and family we have referred to you feel the exact same way. What can we say...you are the pro of pro's! Barbara, we thank you from the bottom of our hearts for finding the absolute perfect home for our family. We have never been happier! We love you!!! Lori & Peter Stern (and Bailey and Logan to!)

Sam Zaidins

I just want to say that it was a pleasure to work with you on the real estate transaction at my residence in San Francisco. Your attention to details, thoroughness, and highest standards makes you the quintessential "best in class" Real Estate Agent in my book. Anyone who knows me will tell you that I am uniquely qualified to state this. And I say this not only because I believe it to be true, but because I not only worked for one of your competitors (Coldwell Banker), but I also hold Broker's licenses in the states of California and Florida. In both states, I have had the benefit of seeing first hand a broad spectrum of working professionals in the industry. There isn't another agent in San Francisco who can hold a candle to you. You exceeded my expectations. I will forever be comparing other agents to you. It is for this reason that I plan to send San Francisco referral business to you.


Barbara knew and appreciated our needs and desires for a new home. The knowledge and professionalism of your firm always impresses me. But nothing has impressed me more than the poise, the taste, the class and the energy of Barbara Callan. McGuire should hold onto her, as she is a true treasure and delight.

Kathleen Purcell

Barbara Callan and Robert Callan, Jr. are the best. They helped our family sell my parents’ house and were incredible in every aspect: planning, staging, marketing, pricing, and closing the deal. They understood the emotional aspects of selling the home in which we all grew up and were sensitive to that dynamic. They brought us multiple stagers to choose from and supervised the staging with an end result that was reasonably priced and beautiful beyond any of our expectations. They made the process of sale easy from start to finish. The thoughtfulness and expertise that they brought to pricing and marketing were very impressive. In a tough market, where many houses, including in our upper income neighborhood, do not sell quickly or have to reduce prices, we had three offers within a week of the first open house, all of them above asking price. Throughout our process, Barbara and Robert consistently demonstrated high integrity, helpful insights, and tremendous capability. These are the Realtors you want if you are selling a home.

Raoul D. Kennedy

Dear Barbara and Robert:

I wanted to thank, and compliment, both of you on the professionalism with which you handled the sale of my house. Even with benefit of 20/20 hindsight, there is absolutely nothing that I can think of that could have been improved upon from your market value analysis, to the quality of the promotional materials, to the way you kept me fully and completely apprised of developments. You managed to exceed even your well-deserved reputation for excellence.

Sandy and Gwen Garrett

Patience, macro and micro economic market knowledge, salesmanship, organization, perseverance, planning, forethought, efficiency, and execution are all hallmarks of Barbara Callan and her team’s style. Mediating issues, dealing with objections, and sound advice all led to a timely successful close of the sale of our house as planned. Who can ask for more?

David and Ceci Tognotti

You and Robert are the Best! It was a pleasure and significant load off our minds to have you representing the property for the Trust, dealing with the Tenants, and, your attention to detail, including handling all of the Inspections and repairs, painting, and the lovely staging. You did a wonderful, top notch job and we are all so grateful for your professionalism in all areas that ended in a timely, successful and uneventful closed sale. No surprise that you are #1 in S.F.--it is very well-deserved!

Thank you so very much, Barbara & Robert.
We will be in touch.


I would strongly recommend Barbara to anyone who is thinking of buying or selling a home. Our transaction went smoothly from beginning to end. Barbara was great! I recommend her to all my friends-she is the best we know in real estate. Barbara offered excellent service and was a joy to work with.

Bill and Catherine Mazer

Barbara & Robert,

We want to “officially” thank you both for the excellent job you did in selling our condo. You professionally handled everything from the pricing and marketing to overcoming the various obstacles.

You are both top real estate agents and have been a pleasure to work with.

Best wishes,

Bill and Catherine

Henry Lo / Jean Houston

Barbara Callan recently sold our house and assisted us in the purchase of another. Through experience we have learned that not all realtors and agents are equal. Barbara is a true professional and will go the extra mile for you. She did for us. She worked diligently on the sale of our house and was extremely knowledgeable in addition to being one of the hardest working realtors we have ever known. She knows the market as well as the real estate business and demonstrated her skills over and over. She was always accessible and stands heads above the average realtor. We highly recommend anyone using her services.

Mike and Barbara Oliver


Now that our condo is sold, the money is in the bank and the dust has settled, we want to express our sincere appreciation for your help. You and your staff were exceptionally professional throughout the process and you made it happen. We have endured many real estate transactions and we can say without hesitation that you are the absolute best realtor we've ever worked with. Your intelligence, perseverance, attention to detail, creativity and pragmatic approach really set you apart. Anybody who doesn't hire you to sell their real estate is settling for an also-ran. Thank you again for doing such a great job for us.

Stephanie Loughran and Peter Yared

Thank you for working your magic for us again - the third time around! We had a wonderful experience with you and it couldn't have worked out any better. Thanks so much for all the hard work in finding just the right buyer for our home and managing a more than complex purchase on the new one. We will definitely look forward to working with you on the next one!

Gerry, Teri and Jack Murphy

Barbara and Robert,

Teri, Jack and I just wanted to express our thanks to you and your team for your work over the past few months. It is pretty hard for us to believe how much life has changed over the short period of less than 3 months. We are very happy with our new house. It's quite a change for us but in such a positive way. We also love the neighborhood and the many new places to explore. We are also greatly relieved that the sale of our old home went so quickly and smoothly.

We know we could not have done this without you guys. Your advice and guidance at all the key moments was frankly irreplaceable. You not only met our expectations, you exceeded them by a wide margin - we could not imagine a better outcome than this. I think your field is filled with too many people who are all show but no substance. Thankfully, you do not fit that norm! You are exceptional professionals and it was a pleasure working with you..

Hank Gates

Barbara, your professional expertise involved in the sale of 182 Commonwealth Avenue-our family house far exceeded my expectations every step of the way. I truly appreciate all of your great quality work and effort.

Shannon Gardner

In the overall scheme of things we spent $30,000 to put our house on the market and this got us $200,000-$300,000 in the overall scheme of things. What you say to people really has tremendous truth to it which is that the few thousand they spend they will get back many times over what they get for their selling price. You and your assistant David were really a tremendous resource for me in this vision that I had of how the house should look. Just a few compliments and thanks again!

Judy and Bill Benedict

We want to formally thank you for making our sale as painless as possible. With your knowledge of our market, your assessment of our houses and great timing we had a quick sale above asking price. We obviously made the right choice and thank you for making our first sales experience a good one.

Robin Raborn and John Lazlo

We asked Barbara for her suggestions a year before putting our house on the market. This gave us adequate time to have the house painted and the landscaping perfected. We followed her suggestions in every detail. We accepted a good, strong offer six days after the house was on the market. Barbara and her assistant David are extremely efficient and calm under pressure. Barbara knows the market and knows how to sell.

Matthew and Michelle Righetti

"Barbara handled both the sale of our Marina house and the purchase of our house in Presidio Heights. We found Barbara to be extremely knowledgeable about the San Francisco market and very well organized. And, Barbara is well respected by her peers - an attribute that was very helpful during contract negotiations with other brokers. We felt that our interests were well represented through the entire process and we would not hesitate using Barbara again in the future."

Michael Lee

When we decided to sell the home that I grew up in 50 years ago, I interviewed 3 top agents in SF of which Barbara was one. Her enthusiasm for her job and our property put her over the top as all three had similar credentials. Its difficult to follow an advisor's plan when property owners experience the sale of a home so infrequently and the stakes are so high. However, Barbara convinced us to prepare and stage the house, and although she priced it less than I expected, her plan brought us the highest price. The moral of this story is that it pays to hire the best expert that you can find whenever you're dealing with a transaction this large and we made the right choice.

San Francisco Design Center-Rhonda Hirata

On the behalf of the San Francisco Design Center, we would like to thank you very much for participating in Winter Market 2008: World View, as a panelist for the keynote presentation, In the Lap of Luxury. We received excellent feedback on the discussion-the audience was enthralled with the quality of its content. Thank you again for your contribution and involvement in the panel.

Sean & Colleen McDonald

Sean and I cannot thank you enough for all that you did to sell our home. Your professionalism and dedication are very obvious and we thank you and appreciate all your hard work. Thank you for the beautiful water color painting of 40 Bonita Street. We will treasure it always.

Mark and Rosemary Armenta

When it comes to selling your home, you need to have a professional who keeps your interests in mind. Barbara Callan was just the right person for the job, her business acumen and intimate knowledge of the neighborhood resulted in overbids and a quick close of escrow. Start to finish: an amazing twenty-four days! In conclusion, it is always a pleasure to work with a true professional.

Ellen Ambrose and Brian Billings

Brian and I enjoyed working with both of you. You are total professionals, brought great skills to the marketing and quick sale of the condo and are nice people to be around!

Susan and Ash

Ash and I very much appreciate the time and effort you gave to us as we searched for a home. We recently closed on a property back on St. Elmo Way, and with obvious endearments, feel very much like we have gone "home." The property has fabulous potential and we are planning a full renovation before moving in. In the future, we do hope to work with you as we look for development projects in San Francisco. We value greatly your professionalsim, knowledge, and integrity within the real estate industry, and certainly see the benefits that brings to the dynamics of a team effort.

Dr. Laurence and Dr. Rupsa Yee

Hi Barbara and Robert,

You two will always be the best. Thank for your sage advice and professionalism. And results! Looking forward to seeing you both soon.


Laurence and Rupsa

Martha Nicholson and Wen Shen

Thank you so much for all of your help closing the deal for 176-180A 6th Avenue. I know this deal only closed because of your determination, your attention to detail, and because of all the relationships you have built with other professionals. It was very reassuring to work with someone of your integrity-and because you kept telling me that you had a good feeling and that you thought it would all work out. I'm not sure if you believed it-but I was happy too! Thank You again!

Michael and Mary Ann Kashiwagi

Mary Ann and I appreciated the diligence and attention you and Robert provided. We want to thank both of you for helping us find and purchase our new home. Your knowledge and professionalism were greatly appreciated!

Janet Mapes

As a first-time home buyer, I had major fears and uncertainties about the whole real estate process. I couldn't have had a better agent than Barbara to totally allay those fears. She immediately grasped the type of place I was looking for, found it for me and was an integral part of each step of the process. I believe her advice during the offer phase was key to my offer being accepted. Her understanding and ability to make me feel comfortable made the whole home purchase experience a pleasure. I will not hesitate to recommend Barbara to anyone looking for the best realtor possible.

Dianne Walling

Regardless of where you live or own property, Barbara Callan and her diligent assistant David where always there to keep you apprised. I live in southern California and was selling a condominium in San Francisco. I interviewed all the top agents in San Francisco. Without a doubt, I chose Barbara Callan. I chose her for her real estate knowledge, her dynamaic personality, her "track record", her inhouse publishing capabilities, and her efficient and professional manner. Barbara sold my condominium at a great price with multiple offers and short escrow. We had our first showing of the apartment on June 6th and escrow closed on July 19. Thank you Barbara!

Ed Ortiz and Dave McMullen

Hi Barbara and Robert,

Just to echo Dave's sentiment in the previous email I want to let you both know that I am very pleased with the entire process in our work together.

I found you both to be extremely professional and have the right mix of market insight and strategic positioning of our property to generate a very quick sale.

If we had listened to the other competing agents our condo would not have even been listed yet.

You both are rock stars in my eyes!

Thanks again,


Nigel Burns and Cheryl Cruver

I have had the pleasure of working with Barbara on four real estate transactions. I cannot imagine navigating the San Francisco real estate market without Barbara. Her professionalism, contacts, marketing skills, suggestions, and experience helped Nigel and I find our dream home in Jordan Park and sell our Lake Street area flat with multiple offers.
Her assistant David provided exceptional service during every step of the process.

Clayton K. Shum, RFC

Barbara is one exceptional real estate agent. She helped me find the place with all the specifications we discussed. She helped eliminate any headache that a buyer would otherwise had to go through. I highly recommend her services and will continue to seek her services in the future.

Diana Richmond, Esq.

Barbara's wise assessment of the market, expertise, cordiality and efficiency allowed me to sell my home quickly, for an excellent price (over asking), with no complications. It was a joy to work with her, and I would recommend her to anyone.

Jon and Stephanie Lenzi

Barbara is very knowledgeable regarding the San Francisco real estate market. Her understanding of the entire buying process made both Stephanie and I very comfortable throughout transaction. We would definitely do business with Barbara Callan anytime. David and Barbara are a great team!

Kathy Renner

All your great marketing put this price over the top. You broke all records for the neighborhood. I can't tell you how happy we are. Thank You!


Recently, Barbara listed, recommended staging and sold our home in the Diamond Heights area. She is an impeccable professional, who provided outstanding service to us. Both Barbara and her team illustrated our property handsomely on her website, which helped to market and expose it to potential buyers. We would definitely call on her to represent us on a future real estate transaction.

Richard Chin and Christina Hyun

Barbara was wonderful to work with. We were shocked, having only met in the most cursory way at an open house, that she returned our call so quickly! She seemed to understand, instinctively that with three young children we prefrred to meet at the house. We really appreciated that! Also, during the buying process we encountered a few glitches; it was reassuring to have Barbara on our side. We felt her experience and professionalism really shined during both transactions. We would be happy to refer Barbara to our friends-as we are satisfied customers!

Doug Hendrickson and Shyla Strange

Barbara Callan did a phenomenal job on both the sale of our old home and the purchase of our new home. She was extremely professional, diligent, and knowledgeable throughout both transactions. Our home was sold for well above asking price, which we solely attribute to Barbara and her team's exemplary marketing efforts. We highly recommend Barbara and look forward to working with her again.

James and Linda Lam

Thank you so much in helping us getting our dream house in St. Francis Wood! Your knowledge of the market is unsurpassed and the services you provided are top notched. We are very impressed with the end results. You can bank on us calling you when we sell our house in the future

Paul and Rachel Nadjarian

"Barbara was a wonderful realtor to work with. She was extremely professional yet reasonable in her approach. Her expertise and know-how shows from the moment you meet her. We have no doubt that her unique combination of skill and style made the sale of our house a complete success."

Brian McDonald, Esq.-2825 Lake Street

Dear Barbara:

In the words of Warren Buffett, "our satisfaction score is 100%! Thank you and your staff for your excellent work.

Ilana Bar-David

Thanks again for your outstanding and thorough work selling our home of 26 years. It was a challenge to prepare the home for sale at top dollar. You and your amazing assistant David were there every step of the way, providing excellent referrals of workers who could assist us in completing unfinished home projects and staging the results. Whew - what a task but working together as a team produced excellent results. You and David are outstanding!

Victor and Victoria Vuong

Dear Barbara:

We would like to thank you for all the professional assistance you have given us particularly in helping us sell our property at 60 Santa Clara Avenue, San Francisco, California. Your expertise is highly appreciated. We will certainly contact you again when we need your assistance. Please do not hesitate if you would like us to be your References in the future.

John and Michele Armanino

Thanks again for all your help. You were always on top of everything and we very much appreciated that! Could you please thank your assistant, David, for me. He was always so cheerful and efficient. I can see he must be a pleasure to work with!

Mary and Hal Cranston

Working with Barbara and her team to sell our home of twenty five years in St. Francis Wood and to buy a condominium in Pacific Heights exceeded all our expectations. Barbara has extraordinary market intelligence which she combines with her many years of experience and wisdom. From her initial assessment of our property, through the negotiation for our new home, she was one step ahead of everyone involved. We have never had a real estate transaction go so smoothly. Her sound and realistic appraisals of the values of both homes allowed us to get into contract and close the properties within 6 weeks in the worst real estate market in a decade. Barbara and her team have our highest endorsement.

Susan Cranston & Russell Hamilton

Barbara and David-
THANK YOU so much for your help in getting our "Dream House"-so quick! We've moved in and settled down to a very nice Parkside life-Thank to you! We're very grateful for all your expertise. PS We couldn't agree with Warren Buffett more!

Dave Bisho

Barbara, thanks very much for your hard work in selling our home. I believe it was your knowledge of the industry and daily attention to details that brought the right price for the house, and the right house for the new owners. And, you achieved this in a very short period of time. The process was seamless, and, a pleasure.

Barbara Ragan

Dear Barbara, Robert and David,

I know this is late but my life this summer has been quite a roller coaster. After getting the house sold, I've driven cross country to settle both girls on the East coast and then returned to find out my dog was dying of cancer. So please forgive my tardiness but I did want to thank all of you most sincerely for all of the absolutely wonderful work you did to get our house sold. I pinch myself when I hear all of the horror stories of other peoples problems getting rid of their houses and think of how lucky I was! But really, I think it's your skill more than luck that did it. Your commitment to excellence and follow through is second to none. Even though it was hard to sell my house emotionally, I couldn't ask for a better experience. It was a pleasure to work with all of you! Thanks for the gift basket. It was unnecessary but greatly enjoyed by many people!
