What health inspectors found (on-site government inspections — the most independent evidence available)
Health inspection rating: ★★★☆☆3/5 · CMS overall rating: 5/5
The health inspection star above is graded on a curve within each state — a set share of each state's facilities gets each star level — so a facility can have few citations and still rate 2–3 stars if others in its state did even better. The overall rating combines that inspection score with staffing and self-reported quality measures.
All citations in the current public record (12)
CMS publishes roughly the last three inspection cycles plus recent complaint investigations. Older surveys drop out of the record as new ones are completed.
| Date | Severity | What the facility was cited for |
|---|---|---|
| May 23, 2025 | F · Potential for harm, facility-wide | The facility did not get its food from approved, safe sources, or did not store, prepare, and serve food according to professional food safety standards. |

Nurse staffing (from payroll records, adjusted for how much care residents need)
| Measure | This facility | New York avg | U.S. avg | Where it stands |
|---|---|---|---|---|
| Total nurse staffing (hours per resident per day) | 7.50 | 3.58 | 3.95 | top 1% in New York; top 1% in the U.S. |
| Registered Nurse hours | 4.51 | 0.68 | 0.69 | top 1% in New York; top 1% in the U.S. |
| Weekend total nurse staffing | 6.69 | 3.13 | 3.50 | top 1% in New York; top 1% in the U.S. |
| Weekend RN hours (not acuity-adjusted) | 3.80 | 0.48 | 0.48 | top 1% in New York; top 1% in the U.S. |
| Total nursing staff turnover (%) | 3.4 | 40.3 | 45.8 | top 1% in New York; top 1% in the U.S. |
| RN turnover (%) | 0.0 | 39.8 | 42.9 | top 1% in New York; top 1% in the U.S. |
Hours are per resident per day, case-mix adjusted by CMS so facilities caring for sicker residents can be compared fairly (same basis as the CMS staffing star). "Top X%" means better than most facilities: more staffing hours, or lower turnover. Raw (unadjusted) reported hours: total 7.99, RN 4.81, weekend 7.14. Staffing rating: 5/5.
Self-reported quality measures
Note: these ratings are based on data the facility reports about itself to CMS. They are not independently verified by inspectors, and can look better than inspection findings. Give more weight to the inspection results above.
Quality measures rating: 5/5 · long-stay residents: —/5 · short-stay residents: 5/5
