Northwell Health Adds Another Hospital

One of the last independent hospitals on Long Island will become Northwell's 23rd hospital, and its fifth in Suffolk County.

Norwell Health has acquired Mather Hospital, a 248-bed community teaching hospital in Port Jefferson, NY. The acquisition is expected to take effect in January, the two hospitals said in a joint statement.

Financial terms were not disclosed.

Mather, opened in 1929, becomes Northwell’s 23^rd hospital, and its firth in Suffolk County, joining Huntington Hospital, Southside Hospital in Bay Shore, Peconic Bay Medical Center in Riverhead and South Oaks Hospital in Amityville.

"This month Mather Hospital celebrates 88 years of service to our community. So it is auspicious that at this time Mather officially becomes a member hospital of Northwell Health. This is a once-in-a-century event that fortifies us for future growth," Mather President Kenneth Roberts said.

"While we are now a member of one of the country's premier health systems, our mission remains the same – to provide our community care to the best of our ability, showing compassion and respect and treating each patient in the manner we would wish for our loved ones," he said.

Mather Hospital began merger discussions with several health systems in early 2016. Mather had been one of only two hospitals on Long Island that had not joined or announced plans to join a larger system.

The merger is the end result of a due-diligence process that began in July. Representatives from both hospitals met over the past five months to iron out the details of the acquisition.

Mather’s service lines include bariatrics, neurosurgery, orthopedics, pulmonology, robotic surgery, breast health, mental health and emergency services. It also operates the advanced radiosurgery program Precision CyberKnife of New York.

Mather’s Graduate Medical Education program offers residencies in internal medicine, psychiatry, radiology and transitional year. The hospital has more than 2,600 employees and more than 600 staff and affiliated physicians. The hospital cared for more than 12,500 inpatients and over 40,000 emergency patients last year. Mather physicians performed more than 3,800 inpatient surgeries and 10,500 outpatient surgeries.

Northwell Health is New York State's largest health system and private employer, with 23 hospitals, more than 600 outpatient facilities, 63,500 employees, and nearly 15,000 affiliated physicians.
