About Me

I began my career in medicine as a volunteer emergency medical technician. I continued to advance because I enjoyed helping people and making a difference. I still ride as a volunteer with a fire department ambulance and am involved with emergency medical services (EMS). I chose internal medicine because it’s all encompassing and allows me to create lasting relationships with my patients.

I believe that prevention is the key to longevity and health. I treat both adolescents and adults with a wide variety of conditions, ranging from simple illnesses to complicated multisystem issues. My team and I offer a comprehensive approach to treatment, and while I may have a busy practice, the vast majority of my patients are in the exam room within 15 minutes of their appointment. I listen to my patients and address their needs.

I was a recipient of the Suffolk County EMS Physician of Excellence Award, and I was voted Best General Practitioner for 2016 and 2018 in the Best of Long Island contest. Also, I am a fellow of the American College of Physicians.
