North Shore University Hospital has appointed Dr. David Hirschwerk, as its medical director, effective today.

Hirschwerk, who spent nearly two decades at Northwell Health, most recently served as executive vice chair of the Department of Medicine at NSUH and Long Island Jewish (LIJ) Medical Center in New Hyde Park.

Hirschwerk is an infectious disease specialist whose focus includes infections in immunocompromised patients. He has been a leader in Northwell’s response to the coronavirus disease 2019 (COVID-19) pandemic. Hirschwerk succeeds Michael Gitman, MD, who was recently promoted to executive director of LIJ.

“Having an infectious disease doctor as our medical director is incredibly helpful during this time, especially one as accomplished, knowledgeable and skilled as Dr. Hirschwerk,” said Jon Sendach, executive director at NSUH. “Dr. Hirschwerk is a well-known, collaborative and respected leader inside these walls and a major reason why North Shore University Hospital has become a top destination for medical services in the region.”

Hirschwerk is an associate professor in the Department of Medicine at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell and completed a fellowship in Clinical Quality.

He was the recipient of the 2021 Goldstein Physician Executive Leadership Award at Northwell. Dr. Hirschwerk received his medical degree from Mount Sinai School of Medicine and later served his residency there. He also holds an engineering degree from Brown University.

“I have been practicing here for nearly 18 years and I’ve developed great relationships with so many terrific people in the building,” said Hirschwerk. “I am especially excited to join an outstanding and experienced leadership team that I’ve already loved working with before my new role. There are so many important projects on the horizon at NSUH and I’m ready to jump in.”

NSUH, a CMS 4-star hospital and destination for cardiac, neurosurgery and transplant, was rated Long Island’s top hospital by US News & World Report and nationally recognized in eight medical specialties.
