Near state avg (7.6)

This facility shows recurring issues across three key areas: food safety and nutrition services, infection control programs, and emergency power systems, with the same food safety violation appearing in all three surveys from 2022 to 2025. While all 15 deficiencies have been corrected by the provider, the persistent pattern of food handling problems and repeated infection control lapses suggests ongoing operational challenges that families should discuss with facility leadership before making placement decisions.
