Initially an FDA trial patient for the Lap-Band in 1999, she converted to the sleeve gastrectomy in 2015.

Your Surgery

We offer three types of minimally invasive, robotically assisted surgical procedures:

  • Sleeve Gastrectomy removes most of the stomach and reconfigures it into a small sleeve shape.

  • Gastric Bypass, the gold standard of bariatric procedures, creates a smaller stomach and bypasses part of the intestines.

  • Adjustable Gastric Band implants an inflatable silicone band around the upper portion of the stomach.

  • Gastric Band Conversion transitions a patient from a gastric band to the gastric sleeve or bypass.
