Detailed profileWhat government inspectors found when they visited in person.
How much time nurses and aides have for each resident, per day.
How well residents actually do on health measures over time.
From government health inspections and reporting · updated July 9, 2026.
Every licensed and certified nursing home is scored from 1 to 5 stars using the same government data: on-site health inspections, staffing levels, and measures of how residents do over time. 5 is much better than average; 1 is much worse. The percentile shows where St John Kronstadt Convalescent Centerlands against other homes — a low score doesn’t always mean bad care today, and a high score isn’t a guarantee, but it tells you what to ask about. Visiting in person is still the best test.
The most recent inspection cycle found 11 deficiencies. No fines were issued in the past three years.
When inspectors find a rule not being met — anything from paperwork to resident care — they record a “deficiency,” and the facility has to fix it. Most nursing homes have at least a few. Fines are money penalties for more serious or repeated problems. Many deficiencies or large fines are worth asking about when you visit.
