Dr Lyass, I cannot thank you enough for saving my life! I have lost 79 lbs since surgery 12/16/08. I was 341 in August of 2008. Now I weigh 230. I feel wonderful!!!
Dr. Lyass did my surgery and what an outstanding doctor. I felt really comfortable and he explained everything pre/post surgery. Thank you so much Dr. Lyass, I owe you so much and would recommend you and the surgery to anyone.
I am very pleased with my care so far. The doctor understands that I had to pay for my procedure because my insurance would not cover it. I got an infection from the surgery and he took care of it as fast as possible. Dr. Lyass seems to care about me and wants me to do well. He keeps in close contact with you if you have any questions or concerns. He was the only doctor that wrote an email to me when I was looking for a surgeon.
