About Advanced Surgical Associates

Leading the way in Innovative Surgery

Advanced Surgical Associates, ASA, was one of the first exclusively surgical groups practicing in Union County New Jersey.  And that is just the first of many firsts for ASA.

For over 40 years, we have pioneered breakthrough surgical patient care in North Jersey. ASA surgeons were among the first to perform:

• Weight loss surgery
• Laparoscopic surgery: minimally invasive hernia, adrenal, hiatal hernia, gallbladder, colon and spleen surgery

Our Philosophy is Unique

We take continuity of patient care further. Our practice is committed to quality of care, not quantity of caseloads.  We believe that fully understanding our patients – their histories, needs, questions and fears – is 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. Feteiha,  Dr. Joao Lopes and Dr. James M. Lopes perform gastric bypass, gastric sleeve and gastric banding (Lap-Band®) procedures as well with great success.
