About Us

History

Mount Sinai Doctors Long Island is a respected practice that has offered comprehensive health care to the people of Long Island since 1946. Our practice began with just three doctors, the first board-certified physicians in Suffolk County. Today we feature more than 70 physicians in more than 20 specialties, who continue to uphold our tradition of quality care. Our practice remains dedicated to providing personalized care, with a focus on prevention, early diagnosis, and treatment. With years of experience, our physicians offer care for a wide variety of conditions including cardiovascular, endocrine, gastrointestinal, kidney and many other disorders. Over the years we have expanded with new offices in Nesconset, Commack, and Bay Shore, and now in Greenlawn.

In 1995, our practice, formerly known as North Shore Medical Group, became part of The Mount Sinai Hospital. Today, we provide easy access to the prominent specialists and latest treatment options offered by the entire Mount Sinai Health System. We actively support many community outreach programs and fundraise for charitable organizations. Our practice works with the Make-A-Wish Foundation® of Suffolk County, raising money and offering our facilities to further their cause. You can rely on the team at Mount Sinai Doctors Long Island to be informed about the changing medical landscape and to provide quality medical care to the Suffolk County community.

Our New Greenlawn Location

To better serve patients in the local community, our Huntington locations have a new home with the opening of a spacious, state-of-the-art office at 5 Cuba Hill Road in Greenlawn.

As our practice expands, the new Greenlawn location will have a growing number of highly skilled physicians and will provide the newest technologies and resources. Our advanced imaging center houses brand-new, state-of-the-art equipment and offers services such as PET scans, CAT scans, digital X-rays, and wide-bore MRI. The Women’s Center provides 3D mammography, a dedicated mammographer/breast imager, and a wide range of advanced OB/GYN services. Our dedicated onsite laboratory is ready to serve patients with state-of-the-art instruments and multiple  specimen collection stations. Our infusion center provides care for patients with cancer and blood disorders with a skilled staff and 12 treatment chairs. Special services include a new immediate care program for all patients, a personalized health care program, and pain management services.

We offer extended morning, evening, and Saturday office hours for primary care, pediatrics, and onsite lab services.

Designed with our patients in mind, our new Greenlawn office ensures a pleasant visit with conveniences such as easy scheduling, ample onsite parking, bright and inviting waiting areas, and welcoming greeters to help you from the moment you walk through our door.
