Hi Christien, I have taken a couple of lessons from Jeff Massanari in Oakland (
JEFF MASSANARI :| GUITAR) and like him a lot, and his lessons are quite reasonably priced. I also took Mimi Fox's introductory jazz guitar class at The Jazz School in Berkeley. This is not a beginning level class--I was in over my head having played for 3 - 4 years at the time--but it worked out well nevertheless. (I met Jeff when he subbed for her a couple of times.) I'm sure there are a lot more good teachers around here, and I look forward to other responses. Good luck!
