All three surgeons have received advanced fellowship training in bariatric surgery; Drs. Vaimakis and Iannace have earned the prestigious status of Fellow of the American College of Surgeons (FACS). Dr. Vaimakis is also a Fellow of the American Society for Metabolic and Bariatric Surgery (FASMBS). He was the first surgeon to perform laparoscopic gastric banding at Englewood Hospital and Medical Center and Holy Name Medical Center. At North Jersey Bariatrics, Drs. Vaimakis, Iannace and Fredericks are committed to helping patients that are suffering from obesity lose excess weight with the help of bariatric surgery — and to helping them set the foundation for making healthier lifestyle choices for the rest of their lives.

Drs. Vaimakis, Iannace and Fredericks have extensive expertise in a wide range of bariatric surgeries, including one of their most-requested procedures, Lap-Band adjustable gastric banding weight loss surgery. Drs. Vaimakis, Iannace and Fredericks also offer gastric bypass and sleeve gastrectomy bariatric surgery. In addition, they will soon be one of a select group of practices that offer the gastric balloon procedure, a 20-minute, noninvasive endoscopic procedure, during which a soft balloon is placed in the stomach to restrict the amount of food that a patient can consume. All surgeries performed at North Jersey Bariatrics are done laparoscopically. During laparoscopic procedures, the surgeon makes several small incisions in the treatment area (i.e., the abdomen) instead of one large incision, as is the case with traditional “open” surgery. The surgeon inserts the surgical instruments through the small incisions. As the name suggests, one of the main surgical devices used in laparoscopic surgery is a laparoscope — a long, thin instrument with a camera on the end of it. The camera transmits a video feed from inside the abdomen onto a screen in the operating room, allowing the surgeon to monitor the progress of surgery. Thanks to the use of several smaller incisions, laparoscopic surgery is less invasive than the conventional open technique.

North Jersey Laparoscopic Associates quickly rose to prominence as a premier weight loss treatment center. Our surgeons, registered dietitian, chef, life coach, exercise physiologist and entire bariatric team are part of a comprehensive weight loss program that includes nutrition counseling, follow-up care and access to support groups. Based on North Jersey Bariatrics’ total care plan and consequent high success rates among patients, our practice was chosen to provide education and training to other practices to help them improve their overall structure, patient care and outcomes. Drs. Vaimakis, Iannace and Fredericks strongly believe in the importance of patient education and of giving patients the tools to lose excess weight successfully — and keep it off over the long run.

Take the first step in improving your health and quality of life — today.

He is a very caring individual and his program encourages support both prior and post surgery and I am all in to get this right!" —Anna

Dr. Vaimakis is medical director of bariatric surgery at both Holy Name Medical Center and Palisades Medical Center; she is also affiliated with Hackensack University Medical Center, Englewood Hospital and Medical Center and Hackensack UMC at Pascack Valley. Dr. Vaimakis is passionate about her work. As she explains, she is “amazed at the difference the surgery makes in people’s lives, not just physically, but socially, professionally and emotionally as well. It is like no other field in surgery because it allows the surgeon to have a lifelong relationship with the patient. It is also the most gratifying field because it gives the chance to really make a difference in someone’s life, and, because of that, I absolutely love what I do; this is why I have dedicated myself to this field.”

Vincent Iannace, MD, FACS, received his Doctor of Medicine degree from Stony Brook School of Medicine before completing a general surgery residency at Brown University, where he was introduced to bariatric surgery. Dr. Iannace then fulfilled advanced fellowship training in bariatric surgery at Hackensack University Medical Center, where he had the opportunity to work under the tutelage of Dr. Capella, the developer of the Capella Procedure.

He is affiliated with Holy Name Medical Center, Hackensack University Medical Center, Englewood Hospital and Medical Center, Palisades Medical Center and Hackensack UMC at Pascack Valley. Dr. Iannace loves performing bariatric surgery because, as he says, “it works. We can finally help change the lives of people who have been struggling with their excessive body weight and add many good, quality years to their lives. Being part of the ‘halo effect’ — which surrounds my patients — lets me feel like a member of their family, and, as a result, find the job very fulfilling.”
