The California Department of Social Services conducts ongoing inspections of assisted living communities. Reviews of TreVista Senior Living have included findings that the community met core health and safety requirements. However, other inspections identified concerns involving resident supervision, staffing, and sanitary conditions.
Families considering the home should ask how it addressed those findings and what improvements have been made since previous inspections.
