I'm not from there so I can't suggest any personally, but I would recommend checking out the CCFA website here
www.ccfa.org/physician and looking at their listings... I did a quick search for zip code 94601 since that is an oakland sanfrancisco zip and came up with a lot of listings. It looks like there are a LOT in San Francisco!!
Good luck! Hopefully someone here can recommend a specific doctor for you as well.

Current Meds:

Should also be on supplements and probiotics and other UC drugs but I'm just not good at taking pills...
