It was in SF, not Sac. Sutter owns EVERYTHING in the Bay Area now, I swear!
I go to PAMF and Sutter owns them now. The way it works at PAMF is that your PCP refers you to the Bariatric center. Then they are supposed to give you a group appointment. That's as far as I got. My neighbor used them for his RnY though and he did lose 50 lb. before he had surgery. He was doing classes and meeting with the nutritionist.
I had trouble getting my group appointment because my insurance has an exclusion and the Bariatric center wouldn't return my calls. So I went outside the group. I had my surgery with LapSF and used CPMC in SF. They are also a Sutter company, but LapSF is independent. LapSF also does surgery other places, but not in the Sac area. They do "clinic" and suport groups out there but you'd have to come to SF for your actual surgery.
