Every time I do things that I’ve never done prior to weight loss surgery, it’s an instant gratification. There was so much I wouldn’t do before WLS from going speed dating to trying sushi! I feel like I’m actually LIVING!!! EVERYONE here is so amazing! Dr. Gonzales is probably my favorite person ever. I am forever indebted to him.

Working on my feet all day, now I have no pains in my feet nor do I lose my breath from walking from point A to B when I would normally. Everything in my life is so much easier now that I am lighter on my feet and feel better about myself. Everyone at the office has always been nice and very helpful. I have and will continue to reccommend this facility and Dr. Gonzales to anyone you can help. Thank you!
