8 state citations (1 serious, 7 minor) and 8 verified complaints since 2022 across 25 inspections. The most recent substantiated finding, from November 2025, involved a resident who developed multiple pressure injuries after admission; the facility's records showed no skin care treatments were documented for approximately 2 weeks following admission despite an active care plan requiring them. A 2023 complaint investigation found substantiated that a resident's room had been in unsanitary conditions on multiple family visits, with feces observed on the toilet and soiled clothing in the shower, and a related finding confirmed the resident was not consistently bathed over several weeks. A 2022 complaint investigation resulted in minor citations for incorrectly billing an SSI-eligible resident at market rate and for staff failing to respond to a resident calling for assistance.
Trevista Antioch is a 131-bed assisted living and memory care community on Lone Tree Way in Antioch, managed by Agemark Senior Living. The community underwent an extensive renovation after joining the Agemark family and features both an assisted living neighborhood and The Villa — a dedicated, secure memory care program staffed by Certified Dementia Providers.
Agemark is a family-owned operator that has been in the assisted living business since the late 1980s, well before the term was widely known.
Dedicated memory care neighborhood
The Villa is a secure, purpose-built memory care community within Trevista, staffed by caregivers who are trained and certified as Dementia Providers — not just a locked wing.

Family-owned operator with deep roots
Managed by Agemark Senior Living, a family-owned company operating 26 communities across six states since the late 1980s — long tenure in the industry suggests stability.
Antioch location
Situated in East Contra Costa County — families coming from other parts of the Bay Area should factor in drive time for regular visits.
