need surgeon who takes medical hmo

Does anyone know of a surgeon in the so cal area that takes medical hmo for gastric bypass?

I have Kaiser for my HMO.  They offered 2 options--either use their surgeons, with only a couple to choose from, or use an outside surgical center they authorize.  I chose the outside surgical group, with a surgeon who had done about 7500 LAP RNY's when I had surgery 4 years ago.  I liked this surgeon, as I went to his support groups and spoke to many of his post op patients there. He was well liked, and patients seemed to be doing well with hardly any complications.  They usually have rules. I also know my surgical groups has deals with Beaver and other groups.  dave
