Zwanger Pesiri Radiology has long participated in the Adopt A Highway® program, sponsoring many signs in the Long Island and New York City area. Their generous concern for their patients and the community dates back to 2008 when they sponsored their first sign along the highway. Because of their commitment and belief in the program, Zwanger Pesiri Radiology continues its conviction by adding six new signs in 2016!

History of Zwanger-Pesiri Radiology

In 1953, Dr. Jerome Zwanger founded his radiology practice to provide physicians and patients on Long Island with modern medical diagnostics in a caring and compassionate environment. He began the practice out of his house, which was located where the current Massapequa office now lies.

He began a partnership with Dr. E.J. Pesiri in 1958, which continued until July of 2001, when Dr. Pesiri retired. Dr. Zwanger continued to practice part-time until he retired in June 2008.


For 60 Years

Zwanger-Pesiri has been establishing the standard in radiology with an unmatched level of patient-centered care, research, education, and commitment to the community. Now headed by Steven L. Mendelsohn, M.D. and Susan Zwanger-Mendelsohn, M.D., Zwanger-Pesiri has surpassed every hospital, every health system, every multi-specialty practice, and every outpatient radiology facility in virtually every facet of radiology. This commitment begins with the patient’s first interaction with the scheduling staff and continues to the last communication with the billing specialists.

Zwanger-Pesiri’s knowledgeable team of caring professionals is dedicated to providing state-of-the-art radiological services with a level of care unmatched in the industry.


Community Commitments

In 2009, Zwanger Pesiri Radiology launched a program called Give Back Sundays, which provides free radiological services to disadvantaged and uninsured Long Island residents. Their entire program is staffed by volunteers, including radiologists, technologists, receptionists, etc. They aim to inspire more people to help each other on Long Island.
