Patient Testimonials

  • Able To Get Around and Not Feel Exhausted!
    Love how I have more energy throughout the day, able to get around and not feel exhausted! Love fitting into smaller clothing. I'm doing activities that I wouldn't have been able to do before. I used to feel so self-conscious of going to the beach. -Leticia W. 6/17/16
  • Promoting a Healthy Lifestyle for my Family
    My physical wellness as a result of the surgery has allowed me to focus on my emotional wellness. My life has completely changed. I am now married and am committed to promoting a healthy lifestyle for my family. I love the program and the support available through the process. -Carla D. 6/17/16
  • Easier Than I Expected
    This was much easier than I expected. The surgery went very well with very little pain afterward. The surgery made changing my habits much easier and also helped with satiety. I hadn't seen some friends for several months and when I approached them, they didn't recognize me! Then everyone wanted to know what "plan" I was on so they could try it. Shopping is also a lot more fun! Dr. Cavazos was very informative and answered all my questions clearly. Every office visit, I am met with a smile and friendly service. -Nancy T. 6/17/16
