Let’s see if the Fediverse works for this kind of stuff:

I’m looking for a teacher of classical guitar. Has to be San Francisco. Prefer someone who specializes, too. (Not just someone in a band who also owns a nylon-string guitar and can play Malageña.)

DMs welcome.

I don't have any personal knowledge of him, but Marc Teicholz has a great reputation.

Another possibility would be Lyle Sheffler. He studied at Peabody and the San Francisco Conservatory.

Lyle Sheffler has established himself as a much sought after classical guitarist in the Bay Area and beyond. Acclaimed for his artistry and creative interpretations, Lyle has a sound that is remarkably personal and uniquely his. As a graduate of both the prestigious Peabody Conservatory and San Francisco Conservatory, he is highly praised by audiences and fellow classical guitarists alike.

Thanks so much for both of these, Doug! I’m getting a little deluged with suggestions now. A very nice problem to have!
