There is also A Dr. May in Wichita Falls. I can't find any research on him but have visited with someone who works closely with him who spoke highly of him. He is the Head of the Bariatric surgery center at the Hospital which is a Center of Exellence. You might check him out too. Again Good luck. BBRN
