Nicole's success story

I hit my goal weight ... and I feel fabulous

I had the gastric bypass. I am Type 2 Diabetic and I wanted to gain control of my sugar. I hit my goal weight in about 5 and half months and I feel fabulous. The procedure has completely changed my life for the better because it has empowered me as a middle aged woman that I can really do everything and anything that I want to do. I don't put an age on anything. I don't say I'm too old for something.

Robert's success story

I was tired of the way I looked. I was tired of the way I felt.

I knew if I didn't change something soon, I was going to be in a lot of trouble. The consultation process was a lot easier than I expected. I was met with open arms. I was treated like I was the only patient here. Not only did they answer all of my questions, they had questions for me to make sure I was the right candidate for the surgery. After surgery and that weight started dropping off, my life started changing for the better.

Eileen's success story

It saved my life.

The driving factor behind me getting my procedure was that I couldn't get up off the floor with my granddaughter. That was my why. That was my big reason for having this surgery done. After surgery, it was a little bit of a struggle with what to eat. What you put in your mouth that you don't even think about. You don't think about what you're eating or how you're eating and portion size. It's what I do now every single day. The procedure has changed my life in so many ways. It saved my life.
