Lilly Steel, MD

My Philosophy and Approach to Wellness...

My close relationships with my patients is what I love about being a Primary Care Doctor. Many of my patients have trusted me with their medical needs since I began practicing in the Riverhead area of Long Island over 18 years ago. My Internal Medicine practice serves the East End of Long Island’s Suffolk County, including Riverhead, the North Fork, and the Hamptons.

Wellness is a simple word but it means different things to different people. The MDVIP program allows me to focus on a personalized wellness program for my patients while providing them with the best medical care. As I myself have matured, I realize the importance of prevention in healthy aging.

By limiting my Internal Medicine practice size, I am able to offer my patients more time to develop individualized health goals that we work on together throughout the year. Through extensive screening tests provided on an annual basis, extended office visits to address multiple or complicated issues, and availability via cell phone, I am able to provide some of the best medical care available to patients along Long Island’s East End.

Outside of medicine, my interests include traveling, reading and cheering on my two teenaged children playing various forms of hockey!
