Meet our Surgeons

Brazos Surgical Group is an established Surgical and Bariatric program specializing in LAP-BAND, Vertical Sleeve Gastrectomy, Roux-en-Y Gastric Bypass surgery and the StomaphyX procedure. We have performed a large number of bariatric procedures, with great success.

We feel that this success is not only because of the top-notch surgery, but also because of the before and after care that each patient receives, to help them achieve their weight-loss goals.
