Our Services

  • Roux-en-Y Gastric Bypass
    Makes the stomach smaller and allows food to bypass part of the small intestine. You will feel full more quickly than when your stomach is in its natural state. While your intake of food is limited, you will experience a sense of fullness more quickly.
  • Sleeve Gastrectomy
    A bariatric procedure in which the surgeon removes approximately 85% of the stomach, shaping the remaining stomach into a tube or “sleeve” about the size of a banana. This restricts the amount of food you can eat and allows for normal digestion and absorption.
  • Bariatric Surgery Revisions
    If you’ve had a prior bariatric surgery and think you may need a modification or revision, our surgeons may be able to help you. While a single surgical weight loss surgery is often sufficient, some patients may not achieve the desired results from one procedure. Our center, in conjunction with your surgeon, can help you reach your weight loss and lifestyle goals through a variety of available revision procedures.

Patient Success Stories


I never thought I could feel healthy again after hitting my high weight of 307lbs. I was always so tired and felt worn out all the time. Since having my gastric sleeve in April of 2017 I've lost 107lbs, gone from a size 22 to a size 12 jean, and feel so much better both physically and mentally. I'm able to go on walks with my husband without getting short of breath, I've gone from needing 3 blood pressure medications to only 1 and I feel like I'm finally living my life again after being so stagnant due to my obesity. Having gastric sleeve surgery was one of the very best decisions I've made in my life, my only regret is that I didn't do it sooner.
