My office is located at 423 Gough Street, in the Hayes Valley neighborhood of San Francisco. Regrettably, the building is not currently wheelchair accessible and requires that you be able to traverse a flight of stairs. Hayes Valley is easily accessible by BART and MUNI. Street parking is ample, though more difficult during evenings when the Opera House or Jazz Center (both a few blocks away) are hosting performances.   I am glad to give you more detailed information about buses, etc. should you need it.
