In My Own Words

Let me tell you a little about myself, my experience, my approach to patients, and my philosophy about health care.

For the initial phase of my medical training, my approach was conventional. I have substantial training in orthodox medicine, having taken residencies and fellowships for 9 years after graduating medical school in 1981. This provided me with a great base from which to develop my own clinical instincts. Indeed, my first position, after completing my formal training was on the faculty of Albert Einstein Medical School, where I engaged in clinical practice, teaching medical students and postgraduate trainees, and conducting research. Within a few years, I chose to go into private practice, while maintaining a voluntary faculty position, to allow for greater flexibility in approaching patient care.

As an Osteopathic physician, my training, though conventional, also exposed me to holistic medicine and an open-minded view of “alternative” healing strategies. As such, I have always sought to learn from other healing traditions and to incorporate these treatment strategies in order to best help my patients.

As my experience grew, I became interested in integrative medicine: combining a traditional approach with functional medicine. While orthodox medicine focuses on the diagnosis and treatment of disease, functional medicine is patient-centered and emphasizes an understanding of the underlying causes of physiologic imbalance in the individual patient. Functional medicine is holistic and considers the optimum functionality of all systems of the body. It incorporates a variety of methods and therapies for supporting those systems and keeping them healthy. These include nutrition and botanical therapies, lifestyle approaches and stress reduction programs. The idea behind functional medicine is that one can not only prevent disease and troubling health conditions but in many cases, reverse them.

Furthermore, to be an effective and thoughtful physician, it is important to approach patients personally and individually. This requires careful listening, thorough evaluations and time. Unfortunately, the way medicine is typically practiced today, these approaches have gone by the wayside. Often, patients feel rushed and without the time to communicate effectively with their doctor or even ask questions. I believe that personalized medicine is extremely important. That means viewing each person as a unique individual, whose physiology results from a combination of inherited and environmental influences.

In addition to  Board-Certification in  Internal Medicine, Allergy and Immunology, and Rheumatology, I am also Fellowship trained and Board certified by the American Academy of Anti-Aging Medicine, where I have also completed a Stem Cell Fellowship and Certification in Peptide Therapeutics from the International Peptide Society.
