David took on a tough situation as my building had a range of items to address and he also had to coordinate with 3 different tenants. As the tenants had restricted times in which they could let him show the building, he worked schedules around them and still got quality buyers in. I lived abroad so david had to handle yard cleanup, removal of my things from storage, coordination with my parents, and more. He worked incredibly hard and took calls at any time of day or night, giving me regular updates. My job is incredibly busy and he handled all communications with tenants and let me know when I had to get involved and when not. I'm pleased with the sale even if I miss owning a piece of San Francisco.


I CAN'T SAY ENOUGH to describe what a great job David did helping me find two terrific properties. From start to finish, he was responsive, energetic and his follow through was nothing shorty of exemplary. You don't just get an agent with David, you get a SF native that has been working in real estate since being a teenager. He knows the neighborhoods, he knows the players, he knows HOW TO GET THE DEAL DONE. Oh and everyone likes David. What more could you ask for? The longer story is that I have owned a number of properties in San Francisco and thus know a handful of agents. I called on three of them to help me find a property in a very short period of time. David was on it from the very beginning. He said, "we can do this, but you've got to be ready and fully on board and committed because it's a crazy market!" I knew it was crazy and I also knew that I needed a committed agent. The others I contacted? They set me up with an automated search. Even my agent from two years ago that I sold a building with was M.I.A. No followup, nada. David and I talked everyday and we landed two great properties. What's more, he helped me rent them! I was out-of-town, and he helped show the units when I wasn't there. We had them rented before the property closed and the closing was 21 days. Amazing. David's great. You won't regret going with him either as a Buyer or a Seller. Go David!

Currently I oversee the global field for the number one prestige skincare company in the U.S. and am on the go 24/7. Because of that I needed someone who was smart, efficient and could handle owning the process from start to finish. Not a small request. That said David is all of them and more. Not only does he handle the process and guide/coordinate all of the people and the paperwork but he is dogged in his pursuit of properties both on and off market. The most amazing thing about David is that he is very clear that customer service is the most important aspect of his role. His combined work ethic and speed of a cheetah response /information gathering is balanced with his elegant gracious manner and kindness. After 30 years of working in large consumer focused companies I can say without hesitation he truly emulates what we would all hope for in a customer facing executive!

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!

– Barbara Ragan

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!

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!

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.
