Thomas' success story

I went in for surgery. An hour later, I came out a new man.

Everybody treated me like a king. The day of surgery, I was excited. The hospital couldn’t be any nicer. I went in for surgery. An hour later, I came out a new man. My recovery was awesome. I was out of bed that day. My wife and kids were my motivation on getting this surgery. They are my whole life. I’m happy I’m going to be around for them.

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.
