PORT JEFFERSON, NY ― Mather Hospital marked its 90th anniversary on Dec. 29 with memories from patients and staff, an historic photo display and events for employees.

The hospital was founded in 1929 through a bequest in the will of Port Jefferson Shipbuilder John T. Mather to “Incorporate under the laws of the State of New York a non-sectarian charitable hospital, to be located in said village of Port Jefferson … so designed and constructed as to permit future enlargement, assuming that future needs may justify such action …”

Over the last nine decades, Mather has grown to a 248-bed teaching community hospital. In all that time, the hospital has had only three administrators.

Among the milestones at Mather:

  • 1929 – John T. Mather Memorial Hospital opens with 54 beds as the first general hospital in the Town of Brookhaven.
  • 1962 – A new wing was dedicated, giving the hospital a new surgical suite, a new emergency facility and a new intensive care unit. The expansion also gave the Hospital a total of 110 beds.
  • 1973 – Another expansion project, adding a new psychiatric unit and the most advanced electronic monitoring equipment for coronary care and the Intensive Care Unit, bringing the total number of beds in the hospital to 203.
  • 1983 – Another wing was added, along with extensive renovation of the existing building and new equipment. Mather Hospital had now grown to 223 beds.
  • 1991 – Fourth major expansion of hospital is completed with dedication of new Contessa Nadia Farber Emergency Pavilion
  • 1992 – The hospital opened what would later be renamed the Frey Family Foundation Medical Arts Building
  • 1997 – Mather reached its current bed count of 248.
  • 1998 – Mather opened a new Ambulatory and Inpatient Surgical Pavilion, which in June 2001 was renamed the Matthew J. and Debra A. Cody Ambulatory and Inpatient Surgical Pavilion.
  • 2013 – Mather received its first prestigious designation as a Magnet® Hospital. It received its second Magnet® designation in 2018.
  • 2014 – Mather welcomed its first medical residents and became a teaching hospital. The first program was for Internal Medicine, and the hospital subsequently added programs for Transitional Year (2015), Radiology and Psychiatry (2016) and Interventional radiology (2018).
  • 2015 – Opened the Calace Pavilion, a major commitment by the Hospital to address the current and future medical needs of the communities it serves. The new pavilion increased the number of single-bedded rooms at Mather, provided space for the growing Graduate Medical Education program and included a new conference center.
