The Best Decision

Vertical Sleeve gastrectomy has changed my life. I am 55years old and have been overweight nearly my whole life.

My hero!!!

I'm like everyone else on this page. I have been overweight my entire life. I've gone up and down the scales. I have wanted to have surgery for a long time but insurance would never cover it. My sister suggested I try Mexico. My first reaction was a resounding No! It's way too dangerous. She told me she knew of some fellow nurses who went and had great results so I decided to do some research....

Dr. Alvarez and Staff are amazing

I didn't tell anyone that I was going to Mexico for surgery. I knew the reaction I would get. But that reaction is not justified when it Comes to Dr. Alvarez and his staff. From the moment you land in San Antonio, you are treated with respect from professionals, until you return to San Antonio for your flight home. Everyone on the staff was amazing. The price is great. It reminds you how...
