"Dr. Davtyan was the right choice for me and for my patients.
When I made the decision to have the LapBand surgery myself, I chose Dr. Davtyan. I knew he was the most respected and experienced surgeon in this procedure. I have experienced first-hand, the amazing results of substantial weight loss, improved health and well being, I continue to send my patients to Dr. Davtyan who are suffering from weight related problems such as diabetes, high blood pressure, high cholesterol and sleep apnea.

It's not just the procedure alone that's responsible for a highly successful outcome, it is the doctor who really understands the frustration his patients have endured in their battle to lose weight.

I am proud to have Dr. Davtyan as part of the Cohen Medical Center and I look forward to a long and successful collaboration"
