lots of t.e.'ers from CA! Grizzly Peak cyclists are a good club, they have a novice riders series twice a year to introduce new riders to group riding skills. I highly recommend it, check their website.
There are many other bike clubs in the Bay Area as well, including ...drum roll....Velogirls, a womens club.
Try different groups, different rides, you'll get a sense of which you like. Don't be nervous, cyclists are a friendly bunch as a general rule ;-)![]()
