Thank you for assisting us in buying and selling homes in and around Portola Valley. There is no one else we would call. You effectively marketed and positioned our properties, listened to our needs, and implemented our desires to the best possible advantage. You're first rate and personal in your business.

Client First

We worked with Cowperthwaite & Company on both the buying and selling of homes in Portola Valley in the spring of 2010. The entire process went quickly and smoothly. We found Peter to be accessible, both in terms of time and explanations, creative in problem solving and kept our best interest in mind throughout the process. Peter has been in the real estate business for a long time and it is evident when working with him, wither its questions about pricing, timing, or any other step in the process, Peter offers many ways to solve the various problems.

Peter is very pleasant and easy to work with and that is helpful in a process that inherently is stressful. He offers many resources to help simplify and expedite the process. Overall we highly recommend him and would be happy to speak with anyone who is considering him as his or her agent.

Professional & Available

We are happy to recommend Peter Cowperthwaite as our real estate agent. Peter represented us in the sale of our home in Portola Valley in the spring of 2010 and was instrumental in finding our new home in Atherton/Menlo Park. Peter is professional in every way. Peter and his co-workers were always available and made us feel that our sale was a priority for them. At a time when the real estate market has not been easy to navigate, Peter has a firm grasp on the home values in this area and was able to bring us multiple buyers in a short period of time. Peter has fantastic suggestions on how to present and market individual homes. Peter is well versed in the real estate market in Portola Valley, Menlo Park, Atherton, and Woodside and he brings this expertise to every transaction.

It was an absolute pleasure to work with Peter and we would not consider using another agent.

Excellent Marketing

My husband Dick and I have sold many homes…. and we found your marketing of our house to be excellent and even above that of the “large” Brokerage houses. We found we could trust and rely on your advice. I can say without hesitation we were very happy we followed Peter's advice, his upbeat personality make him a pleasure to deal with. He was excellent and professional in every respect.

Dear Peter, I have sold many homes and I just wanted to say thank you so very much for all the time & effort you spent helping me find my new home. Your sound advice and excellence in negotiating the transaction coupled with a cheerful & professional attitude and excellent follow up (after the close) have made this purchase that much better. Thanks so much.

“It was truly a pleasure to work with Shaler. Her knowledge of the real estate market

and attention to detail helped facilitate the entire process for us. She was positive,

kept us well informed, and was always available to address our questions and

concerns. She helped us find our dream home and within a week was able to sell

our old home for more than we were asking. Shaler was professional, patient, and

exceeded our expectations on many levels.” –Chris & Michelle, Portola Valley

Dear Peter, Doing business with you and Cowperthwaite and Co. has been a pleasantly painless experience. After living forty years in the same house it was a difficult decision to put my home up for sale. You allayed my concerns from the first meeting. In the seven days my home was open to the (? See letter in the binder) you referred, 56 people came, some two and three times; a few planned where this or that might fit and measured spaces. I thought three or four people might submit an offer but in truth fifteen! I was sorry I could only pick one family. I am grateful for the rapidity with which you closed the sale and the personal attention I feel you provided me. I have expressed to friends and neighbors the satisfaction of doing business with you. Thanks Peter. A very grateful customer,
