About Us


In 1986 Jane Singer and Katherine Lee founded Garden Design to serve a close-knit clientele in the Mill Valley area. Over the years, the company has expanded to provide garden services throughout the Bay Area. Today, our work can be found in Marin, Napa, Sonoma, San Francisco, and the East and South Bay.

In 1999, Katherine’s son Doug Lee joined the company, and a year later, it was incorporated as Mill Valley Garden Design. In 2001 Katherine retired, and Doug succeeded her as a managing partner.

Today, Mill Valley Garden Design continues to create sustainable, long lasting outdoor spaces for a wide range of clients.
