We used to have chapters at UCLA, USC, and Berkeley, but they are inactive. A former International President was from Beverly Hills, CA. I'm sure that there are alumnae living on the West Coast. I checked the Alumnae Association section of the International website and see that there is a California AA chapter. If that doesn't help, maybe you can start an AA in your area if you are feeling particularly industrious. You can always contact Headquarters for info. Good luck!
