Meet Our Team: Our Team

I graduated from NYU Medical School in 1996 and went on to do a General Surgery Residency at Saint Vincent’s Medical Center in New York City. I became interested in Advanced Laparoscopy and decided to pursue additional training. I did a fellowship in Advanced Laparoscopy at Montefiore Medical Center’s Institute for Minimally Invasive Surgery in New York. It was there that I was introduced to Bariatric Surgery.

I was amazed at the difference the surgery made 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 the most gratifying field because it gives me the chance to really make a difference in someone’s life. Because of that, I absolutely love what I do and have dedicated myself to this field.

 It would be a pleasure and an honor for me to help you on your journey to a healthier life.

Meet Our Team: Team Members


Registered Dietitan and Exercise Physiologist

Allison obtained a Bachelor of Science degree in Exercise Science from Skidmore College and a Master of Science degree in Nutrition and Exercise Physiology from Columbia University, where she also completed her training as a registered dietitian. She is a member of the Academy of Nutrition and Dietetics, the New Jersey Dietetic Association, the Weight Management Dietetic Practice Group, and the Medical Nutrition Dietetic Practice Group. Allison believes that nutrition counseling is an individualized process. She knows that each and every client that walks into her office is unique and have different needs and goals. As a result, Allison takes a great deal of time and care to ensure they each receive the support, guidance, and expertise they deserve. There is much more than solely diet analysis and modification in Allison’s counseling sessions. As a team, she works with each client to help identify certain behaviors in order for them to feel empowered to create new, healthier habits that will improve their overall wellness and achieve their goals.



Registered Dietitian

After working in the community for Rutgers University Cooperative Extension Supplemental Nutrition Assistance Education Program (SNAP-Ed) and the Robert Wood Johnson's "Power Over Diabetes Program," I learned about many of the contributing factors that have led to the obesogenic environment that we live in today which is setting the way to many nutrition-related chronic diseases. By providing nutrition education and individual counseling, I have witnessed so many of my patients reached their individual goals. These include weight loss; decrease in blood pressure; and the lowering of sugar and cholesterol levels in the blood.

I have experience in adult and pediatric weight loss and management. In addition, I provide nutrition counseling to patients with pre-diabetes, Type 2 diabetes, and certain gastrointestinal disorders.
