  • Dr. Ahmad has changed my life in an amazing way. I had gastric bypass 6/7/2011 and have lost 125 lbs. in 18 months *. With the weight loss i found a 10 cm benign tumor in my breast and had a mascectomy and now I’m perfectly healthy. His staff is so kind and caring and will help you get over the mountains in your new journey in life. Dr. Ahmad is the god of bariatric surgery. I recommend him to EVERYONE with a weight problem looking to make a change in their life.

  • Dr. Ahmad and his team, performed the gastric bypass on me May 2011. The best decision I ever made. A side note, I had attended a few surgeons seminars and found Dr. Ahmad’s the most informative and was able to see his passion for the work. God bless his team and the work they do.
