Gary Davis teaches a course at the Lifelong Learning College. Gary is extremely knowledgeable and an excellent instructor. Gary also runs the Advanced Acoustic Guitar Club but I would recommend that beginners stay away from that.
The Thursday morning Acoustic Guitar Club at Paradise Rec Center is excellent for beginners if you know a few basic open chords. You can learn these chords yourself on youtube or from countless internet sites.
I'm not saying to not take lessons, but you can get started on your own on the internet. Or go to a music store and buy a basic chord book. Also buy a clip on tuner. I have a Snark and really like it.
A capo will help a beginner immensely. It is a little device that clamps the strings down a any fret so that you can play the chords in different keys. In other words, if you play a C chord with your capo on the second fret, it becomes a D chord. You can't use it for every song, but a lot of songs are just three chords and a capo can help you to survive a basic guitar club until you learn some more chords.
If you come by the Thursday morning club come over and say hi to me. You can sit next to me and I'll try to help you out a bit.
Here's a basic "must know" chord chart.
To read this, and all chord charts pretend that you are holding your guitar facing you with the headstock on the top.
I see a lot of beginners come into these clubs and sit there for a while and then leave which is really too bad.
I'll be happy to answer any questions you might have until you find a teacher.
