Marc,
I attend meetings of SIA (Survivors of Incest Anonymous) and they help me a lot. Most areas do not have the meeting information online. You would have to contact the World Service Office. They're volunteers, so it can take a few days to get the information back.
The phone number is (410) 893-3322. The web site is
http://www.siawso.org . If you click the "Literature" link you can print the order form. The "Starter Packet" and "Expanded Packet" each include a meeting directory listing for one area. I got the expanded packet and then some additional items later, and they are helpful for me. You should know that they are written with both male and female survivors in mind, and that can bother some guys. It's not been an issue for me, and the meetings I attend are for both male and female survivors. But some areas have male only, female only, etc. I did see the California directory LA once, but I don't remember how extensive it is.
HTH,
Joe
