San Francisco Surgeons

Hi All- I have been thinking of WLS for 10+ years and am finally taking big steps towards really doing it.     I have been researching WLS and my insurance (Aetna POS) covers the following surgeons:   Dr. Andrew Posselt   Dr. Marco Piatti   Dr. Upadhyay   Dr Albert Wetter   Dr. Pamela Foster I have a consultation with Dr. Foster at the end of May, but she is about an hour away and I am looking into the other surgeons who are closer to me... has anyone seen and had success (or horror stories) about any of these surgeons?  Any advice will help!!!
