About Our Weight Loss Surgery Program

Our practice is committed to quality of care, not caseload quantity. We take our continuity of patient care further. We believe in understanding our patients fully – their histories, needs, questions and fears. This has always been an integral part of the individual medical treatment at Advanced Surgical Associates.

Thanks to our cohesive group structure, every ASA surgeon knows each patient and understands the details of every case. This ongoing collaborative process ensures added value of care for every patient.

Dr. Muhammad Feteiha, a native of New Jersey and highly recognized and experienced bariatric surgeon, started the bariatric department at Overlook Hospital. Dr Joao Lopes is also a native to this area, and is highly regarded by his peers  in his field of expertise including Advanced Laparoscopic Surgery and Bariatric Surgery. He was at the forefront in developing and cultivating the Weight Loss program at Trinitas Regional Medical Center.

Dr. Feteiha,  Dr. Joao Lopes and Dr. James M. Lopes perform Lap-Band® and Realize Band® procedures as well as gastric bypass and gastric sleeve with great success.
