My name is Jennifer Robinson and I have been a board-certified Family Practice Physician Assistant for 18years. I graduated Long Island University of CW Post in 1997 with a bachelor’s degree in biology. I then attended New York Institute of Technology and graduated in 2001 with my Physician Assistant degree. With a strong passion for health and wellness I had the desire to broaden my scope of knowledge by training with board certified doctors and clinicians in the field of Anti-aging (the early detection, prevention, treatment and reversal of age related dysfunction, disorders, and disease) and Functional medicine (approach that focuses on identifying and addressing the root of the problem). I truly believe the key to good health is treating the body as a whole. I strive to treat my patients as the individuals they are. No two patients are the same and in believing that, I provide my patients with care that is specific to their physical, emotional, chemical, nutritional and hormonal needs. The key to giving the best care to each of my patients is based on 2 very important skills. One is to listen; the other is to ask the right questions. My goal is to diagnose and treat the ailment, not just put a bandage on the symptoms.
