Last Health inspection on May 2025
Located at 75 North Country Road in Port Jefferson, John T. Mather Memorial Hospital is a 249-bed facility operated as a voluntary non-profit community. It holds a perfect 5-star CMS rating and ranks highest in New York for nursing staffing intensity. The facility offers orthopedics, bariatric surgery, cardiac services, and neuroscience programs.
The facility’s distinguishing characteristic is unmatched staffing depth.
Nurses work 8 hours 53 minutes daily per resident; more than double New York’s typical 3-hour 29-minute average. All 163 staff members are direct employees with no contractor reliance. The roster includes 22 registered nurses, 37 certified nursing aides, 10 speech-language pathologists, 14 respiratory technicians, and specialized occupational and physical therapy personnel. Weekend coverage maintains 8 hours 13 minutes per resident.
Regulatory compliance is document-perfect. A September 2025 inspection yielded no deficiencies. Over four years, the facility accumulated 12 health citations, well below state average, with zero critical or serious violations. Three citations involved infection control; the remainder addressed resident rights, care quality, and administrative matters.
Zero federal penalties have been assessed in the past three years, and complaint investigations number zero.
Vaccination rates for short-stay residents exceed 98% for pneumococcal coverage and 99% for influenza. No short-stay residents newly initiated antipsychotic therapy; a 100% improvement over state patterns.
However, significant legal exposure must factor into decision-making. Since 2012, the facility has been named in 77 lawsuits. Thirty-two cases remain active as of May 2026, with court proceedings scheduled for April 27, 2026. This volume of concurrent litigation, independent of the facility’s strong inspection record, signals ongoing legal disputes that represent material risk.
John T. Mather delivers exceptional clinical staffing and regulatory compliance but carries substantial litigation exposure that requires thorough evaluation before placement.
In New York, the Department of Health, Office of Aging and Long Term Care performs unannounced onsite inspections to monitor compliance with state and federal healthcare regulations.
