About Zwanger-Pesiri Radiology

Our History

In 1953, Dr. Jerome Zwanger founded his radiology practice with the purpose of providing physicians and patients on Long Island with modern medical diagnostics in a caring and compassionate environment. His partnership with Dr. E.J. Pesiri began in 1958 and continued until July of 2001, when Dr. Pesiri retired. Dr. Zwanger continued to practice part-time until he retired in June 2008.

Headed by Steven L. Mendelsohn, M.D. and Susan Zwanger-Mendelsohn, M.D., Zwanger-Pesiri has grown into one of the most respected radiology practices in the U.S. today.
