Amy moved to San Francisco ten years ago, and has been fortunate enough to work with some of the finest artists and arts organizations in the area as staff, consultant, or Board member. These include the San Francisco Boys Chorus, Cazadero Performing Arts Camp, Chanticleer, LEVYdance, The Crucible, the Ruth Asawa School of the Arts, and composer/DJ Mason Bates.
