Diana Hammer
I offer you knowledge, experience, and reputation as your realtor. I've been working full time since 1987. I have sold houses in every price range throughout Marin. I know the nuances of neighborhoods, of mini climates and of schools. My experience makes me equally comfortable in dealing with a young family with children just starting out or a death in a family requiring the organization of a large estate. I cherish the variety and intimacy in my work—it is always meaningful, never superficial. My reputation precedes me and is perhaps my most important asset. When I am writing an offer for you, the listing agent will know me or about me—your offer will gain value due to my reputation. When I represent you as a seller, other agents will know they can trust what I say about your property and that I have been fair in helping you place a value on it. I have a large network of specialists who help me do my job including termite inspectors, stagers and contractors. I have built relationships with them and the different town inspectors over the years. I am partnered with Callie Hammer and together we formed The Hammer Group in 2020. I appreciate her tech and marketing skills. Her energy makes everything more fun! I work for Golden Gate Sotheby's International Realty, a highly esteemed Bay Area company. We have been impressed by their supportive nature and cutting-edge market knowledge. The office culture is kind and supportive. A University of California at Berkeley graduate, I lived in Ross in Marin County for 40+ years and raised my four children there. I have recently moved to San Geronimo Valley where I love the beauty and peace. I speak French, Spanish and Tahitian. I love living in Marin. Although company statistics state I am a top producer, my ultimate goal is to provide a consistent, thoughtful, caring, dynamic kind of real estate experience with my client’s needs foremost. My business comes from satisfied clients and their friends.
