About Us

Clients benefit from my experience and love of the business


Patricia Oxman - Broker


Hello Marin Sellers and Buyers!

I began my career in real estate as a Broker for Frank Howard Allen where I immediately earned Rookie of the Year status. I went on to enjoy a 20-year run consistently as one of their top producers. I attribute my success to excellent communication skills, extremely disciplined work ethic and a love of the business. When Frank Howard Allen sold in 2014, I elected to move my business to Golden Gate Sotheby’s International where my clients have benefited from the reach and reputation of the Sotheby’s brand.

Prior to my career in real estate, I flew internationally for Pan Am out of New York and later was the Director of Marketing for UOP School of Dentistry in San Francisco. My husband is a real estate attorney so my segue into real estate sales, when our two sons were young, was a natural. Both boys now have young families of their own – one in Eugene, Oregon and the older just blocks away from our home in Greenbrae.

With over 25 years representing both sellers and buyers in Marin, I have extensive knowledge of the marketplace and a strong backing of satisfied clients who have relied on my judgment through a variety of market conditions. My goal is to deliver an unmatched real estate experience for my clients before, during and after each transaction.
