About Me

When I was a child, I dreamed of becoming a doctor. Having been raised by a father who had a psychology practice and a mother who taught science, I learned early on about the joys and privileges of helping those in need. I became an internist because I love following my patients through the course of their lives and attending to every aspect of their healthcare needs. I also enjoy the opportunity to teach medical students and residents.

I believe that the art of hearing is at the heart of healing. It is so important for physicians to truly listen to their patients. At Riverhead Internal Medicine, we pride ourselves on using this philosophy to help form long-term relationships with our patients. I still see patients who I first treated when I started to practice in 1991.

Our wonderful patients have a full spectrum of acute and chronic medical conditions, including hypertension, diabetes, asthma, and chronic obstructive pulmonary disease. We see adult patients 18 years of age and older. Our office offers a variety of primary care procedures, including electrocardiograms, spirometry, and tympanograms.
