3 state citations (1 serious, 2 minor) and 0 verified complaints across 7 inspections since 2024. The facility opened under new ownership in early 2024, with Andrew Mente as applicant and Andrew and Les Dee as initial administrator, and has since transitioned to administrator Shelly Yamishiro as of the February 2026 annual inspection. The 1 serious citation and 2 minor citations were identified during the inspection period; the most recent annual visit on 2/9/2026 was conducted unannounced and reviewed the full facility using the state CARE compliance tool. 2 complaints were filed, both investigated and found unsubstantiated, including an allegation that staff failed to seek proper medical attention for a resident with leg swelling and an allegation that staff restricted phone access, neither of which was corroborated by staff interviews, resident interviews, or documentation review. Annual inspections have consistently documented proper medication storage, adequate staffing, current CPR training, and posted resident rights.
