About Us

North Shore Radiation Therapy was the first free-standing radiation therapy center on Long Island. In 1988 we opened our doors in Smithtown, New York. Now twenty years later we have introduced our new state-of-the science center in Greenlawn, New York. With four Radiation Oncologists, dedicated and talented Management and Clinicians, we have become thought leaders in our field. With publications accepted worldwide in peer reviewed journals and lectures at international meetings, we have the expertise and technology to make a difference.

ACRO SEAL LOGOWe are also proud to hold the distinction of an elite group of centers that are fully accredited by the American College of Radiation Oncology (ACRO).

In 1989 North Shore Radiation Therapy of Smithtown (formally known as North Shore Medical Accelerator) was opened and has quickly become the leader in radiation medicine in Suffolk County. We are fully certified by the American College of Radiation Oncology. Our staff of physicians, nurses, therapists, physicists and business personnel comprise a unique group of dedicated individuals, hand picked for their expertise in dealing with serious illness. We strive to preserve an environment where the patient can maintain their self-esteem and dignity during treatment.

In 2008 North Shore Radiation Therapy of Huntington opened it's doors to unveil a state-of-the-art radiation treatment facility in the township of Huntington, where we provide the most technologically advanced cancer treatment available on Long Island, New York. After eight years of planning, design and construction, this premier Radiation Oncology practice in Suffolk County has opened. This new facility features a Varian Linear Accelerator that will allow physicians the ability to target tumors more accurately and adjust patients positioning prior to treatment, thus improving the precision and effectiveness of cancer treatments.

In Mid 2009 CyberKnife of Long Island opened it's doors in Suffolk County.  This addition to our cancer treatment arsenal shows our commitment to providing the most advanced cancer treatment available to Long Island.
