Nothing in the records stands out as a warning sign. The detail below is still worth reading before you decide.
These are drawn straight from Medicare's records. We report what the record says — we don't rate facilities or judge the care given in them.
Who's actually on the floor
Staffing is the thing most closely tied to day-to-day quality of care, and it's the number families most often never see. This is registered nurses only — a smaller figure than the all-staff total above, because it counts the most highly qualified staff on their own — per resident, per day, comparing an average weekday against an average weekend.
Registered nurses only — hours per resident per day. Longer is better.
Registered nurse coverage is about 16% lower at weekends.
Staff turnover: 3%
High turnover matters because continuity does — a nurse who knows your mother notices when something is different about her. Someone on their second shift doesn't have that baseline.
What inspectors found
State inspectors visit at least once a year and after complaints. Over the last three years this facility received 12 citations. Raw counts mislead, though — a paperwork slip and a resident being harmed both count as one. Here they are by how serious inspectors judged them.
| Severity | Citations |
|---|---|
| Potential for harm | 10 |
| No harm | 2 |
0 of these came from someone filing a complaint rather than a routine visit — worth weighing differently, because it means a person picked up the phone. All findings are recorded as corrected.
Disclosed affiliations
Medicare requires every facility to disclose the people and companies connected to it. Most names below are not owners — they are officers, directors, managers, trustees, and what Medicare calls “additional disclosable parties.” The role beside each name is the one Medicare recorded. This is worth reading because operators tend to run their facilities alike: where the same group stands behind a dozen homes, the record across all twelve tells you more than any single inspection does.

Worth asking on a visit
Records only tell you so much. These are the questions this facility's particular numbers suggest you ask — go on a weekend if you possibly can.
