Our Staff

While there is no doubt that a skilled bariatric surgeon is required for the best results in a weight loss operation, it also takes a dedicated and knowledgeable support staff. A patient has many needs both before and after surgery and the staff can make the difference between good and great results. Learn more about our staff.

Advanced Surgical Associates is 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 in both general and weight loss surgery. ASA also offers gastric bypass, gastric sleeve and gastric banding to those suffering from obesity in New Jersey.
