Looking for a PCP at Kaiser, Riverside, CA

Hello all! I am new to the message board. Today's actually my birthday and as a gift to myself I am researching Lap Band surgery. Right now I'm trying to figure out how to work through the insurance process. Even though I've been with Kaiser in Riverside, Ca for a year, my PCP has moved on and I have to establish a relationship with a new PCP. I've read that it's key to the approval process to get a PCP who is a supporter of this surgery. Does anyone out there have experience with a PCP at Kaiser in Riverside, Ca? If so, who? I want to request a primary care physcian who will support my efforts to get approval for surgery.

Thank you!
