Mount Sinai Health Acquires South Nassau Hospital

The 455-bed nonprofit medical center and teaching hospital was one of the last independent hospitals on Long Island. It becomes the eighth hospital in Mount Sinai Health System. 

South Nassau Communities Hospital will become the flagship hospital on Long Island for the Mount Sinai Health System under an acquisition announced Wednesday.

Financial terms were not detailed, but Mount Sinai said it will provide $120 million for South Nassau’s five-year master facility plan, which will expand surgical facilities, intensive care units, and South Nassau's emergency department, according to a joint media release.

"The addition of South Nassau to our Long Island network represents our commitment to broadening access to innovative treatment and research in this region," said Kenneth L. Davis, president and CEO of Mount Sinai Health System.

"This transformative partnership will complement our existing network of talented clinicians and facilities," Davis said. "We are thrilled about what this means for patients and families on Long Island, and look forward to working closely with our Long Island partners to continue advancing care in the region."

South Nassau's board of directors will retain governance over the day-to-day operations of the 455-bed hospital, until now one of the last independent hospital on Long Island. South Nassau CEO Richard J. Murphy will report to the board and to Davis. The South Nassau Board will include two new members from Mount Sinai's Board, and two members of South Nassau's Board will join the Mount Sinai Board.

The two health systems signed a nonbinding letter of intent last May. Now, a state regulatory review is underway, but hospital officials said they anticipate final approval within months.

"We are in the midst of tremendous growth and expansion at South Nassau," Murphy said. "Our plans to renovate and nearly double the size of our emergency department in Oceanside are already underway, as are plans for a new, four-story, high-intensity building in Oceanside, as well as expanded medical services in Long Beach. The relationship with Mount Sinai will accelerate our plans and provide essential services to patients throughout Long Island."

South Nassau, a nonprofit medical center and teaching hospital, has 3,500 employees and 900 affiliated physicians. It will become the eighth hospital in Mount Sinai’s $7 billion health system, which includes the Icahn School of Medicine, seven other hospitals, 300 ambulatory practices and more than 6,500 physicians.

"Long Islanders shouldn't always have to travel into Manhattan for advanced cardiovascular, cancer, orthopedic, or neurological care," said South Nassau Board Chairman Joseph Fennessy, who led the negotiations. "Our goal from the outset was to find a partner seeking to expand services on Long Island who, like us, puts patients first, employing cutting-edge science and treatments."
