SFSU has one, but I've heard rumours about the restructuring there that may be problematic (budget cuts, etc.) I even wanted to take extra classes there for the summer and the advisor discouraged me (yikes) and told me to take them at UCBx instead. Surprised the last poster didn't write about Mills. It's a private college, but excellent PB program. Apply early though. CSU East Bay is OK, haven't heard much about it. The majority of Bay Area PBs = Mills, SFSU and UCBx.
I believe UCLA has one, USC definitely has one, and Scripps as well.
