I'm a KP member in CA also. After you finish the 12 week program and all the requirements are met such as the labs, chest X-ray, the psych evaluation, then you can call your coordinator and ask to be referred to the surgeon. The surgeons office will call you and schedule a consultation. If they see your are ok for the surgery then they help u pick a day. Then you have a pre op appt 2 weeks before surgery. I really recommend the premier protein shake diet. It is well worth it. Usually they want u to lose 10% of your weight prior to surgery. It helps when you see the surgeon. Hope that helps.
