Karen Gottlieb, in San Francisco, would be one. She may still teach in Marin County. She is on the faculty of San Francisco State University, I believe. She can certainly refer you to someone if necessary. If you can’t find a way to reach her, email me.
Jessica Siegel and Esther Lee teach in Walnut Creek at Harp’s Etc. They are both excellent teachers–I studied with Jessica for 10 years. Check out the Harp’s Etc. website harpsetc.com.
