Dr. Barker did my surgery on November 1, 2007 and I am really pleased with the results. I have lost 57lbs and counting. Sometimes the office is REALLY busy, but if you're just in there for a fill it's usually pretty quick. My insurance required me to visit him monthly for 3 months prior, before they would even approve me.. so I got all my questions answered then. If you don't feel comfortable, it can be pretty scary! I would just schedule another appointment, and wouldn't leave until all my questions were answered. I wish you luck on your journey, it's a crazy ride but so worth it.
