Dr. Steven Mendolsohn

President & CEO, Zwanger-Pesiri Radiology

Dr. Steven Mendelsohn first joined Zwanger-Pesiri Radiology in 1983 as a staff radiologist. Less than a decade later, he became the managing partner. But even now, as the CEO, his philosophy toward the medical industry has remained the same: He believes there is always room for tremendous improvement. Through his leadership along with his wife Dr. Susan Zwanger-Mendelsohn, Zwanger-Pesiri has grown to more than 20 locations. Along the way, it has pursued vigorous partnerships and inspiring collaborations with a wide range of providers in the healthcare field. From its founding in 1953, Zwanger-Pesiri has been regarded as one of the pioneers in the practice of radiology, with its emphasis on providing modern medical diagnostics in a caring and compassionate environment. Today, in virtually every facet of radiology, it has surpassed other hospital systems in the area. Dr. Mendelsohn ensures that a commitment to providing the highest quality services to patients never wavers, from their first appointment to the last. His team of knowledgeable, caring professionals is the top in their field. Thanks to his insight, Zwanger-Pesiri was a national show site for Siemens’ advanced MRI and CT systems, demonstrating this state-of-the-art technology to medical professionals around the country. As he once put around the country. As he once put it, these PET/MRI devices are “radiology’s answer to cancer.” He’s certainly contributed to the health and well-being of countless Long Islanders, who would not be alive today without the skills that Zwanger-Pesiri provide — and that’s the power of healing that Dr. Mendelsohn shares.
