Dr. Lyass is an amazing doctor I got a gastric sleeve surgery and it was such a breeze. Honestly no pain or any complications whatsoever. He is an amazing doctor really listens and cares what you have to say or need. If you are having second thoughts please trust me don't this is an amazing surgery and will change your life forever. I have lost more than 70lbs in less than 3 months, and if I can do it honestly anyone can. Especially when Dr. Lyass is there with you for every step of the way.

Dr Lyass is the best!!! I originally had a lapband surgery in 2007 and after losing 60 pounds initially, it became increasingly difficult to find the "green zone" with my band. I decided to have the band removed and replaced with the gastric sleeve surgery. Dr Lyass performed the surgery in July of 2018, along with repairing a hernia which had developed with the band. I am so happy with the results and am feeling so much better now!! I will be forever grateful to Dr Lyass and his wonderful staff for taking such good care of me!! I can't recommend him enough!!

After five endoscopys, and seeing six bariatric surgeon Dr. Lyass was the only person who stepped up to the plate to perform the necessary surgery for the hiatal hernia. Ten years ago I had gastric bypass surgery and lost over one hundred and forty pounds but over the years I gained at least thirty pounds, which terrified me. One of the complications were acid reflux, bloating and severe gas. During our first consultation he agreed to fix the the hiatal hernia since then I lost close to twenty pounds and counting. It’s only been two months from the original surgery date. I have notice no more gas, bloating and the acid reflux is gone. Thank God for Dr. Lyass he is the best because he healed and cured all my symptoms. I feel like a new woman, my self-esteem has elevated to the roof. I am more confident and self assured about my looks. If there is anyone contemplating bariatric surgery he is THE MAN. I love Dr. Lyass and I could not have done this without his support. Again, thank you for all your help.
