9 state citations (1 serious, 8 minor) and 6 verified complaints since 2021 across 10 inspections. Substantiated complaints include a December 2022 finding of active cockroach infestation in the kitchen, with live cockroaches observed in cabinets, roach droppings in cabinet corners, and grease-stained walls and ceiling; the facility responded by purchasing a new stove and committing to cleaning and repainting. A February 2023 substantiated complaint found residents with restricted water access after a pipe burst, with walls torn open for repairs; the facility provided gallons of stored water for basic use during the disruption. A June 2024 substantiated complaint found the air conditioning had failed during a week of mid-80s temperatures, leaving the facility quite warm before the unit was repaired within days. The December 2024 annual inspection documented hot water at 127.4°F, above the required 105-120°F range. The January 2026 inspection found infection control practices and safety measures maintained.
Mountain View Cottages is a 6-bed memory care facility in Diamond Bar, part of the Mountain View Centers network specializing in Alzheimer's and dementia care. The facility is designed specifically for residents with challenging behaviors including wandering, combativeness, and sundowning — cases that other facilities have turned away.
Led by administrator Smita Sanghvi, the staff is trained to uncover individual residents' preferences and triggers based on their life stories, rather than applying one-size-fits-all approaches.
Specializes in the cases others refuse
Multiple testimonials describe Mountain View accepting residents who were removed from other facilities due to extreme behaviors like escaping, combativeness, and severe agitation. If your loved one has been turned away elsewhere, this facility specifically handles those situations.
Person-centered dementia approach based on life history
Staff is trained to understand each resident's past experiences, preferences, and triggers. Shower time preferences, approach techniques, eating motivation, and activity engagement are all tailored to the individual — not standardized for staff convenience.
Accepts Medi-Cal through the ALW program
Participates in the Assisted Living Waiver, which can significantly reduce costs for eligible residents. Memory care facilities that accept ALW are uncommon, making this a valuable option for families navigating affordability.
Beautifully maintained grounds
The website highlights landscaped gardens, cozy home-like settings, and tastefully designed private and semi-private rooms in scenic foothill surroundings. The physical environment matters for residents with dementia — calming, well-maintained spaces reduce agitation.
Higher-than-typical substantiated allegations
Six substantiated allegations out of 9 total is notable for a 6-bed home. The nature of the resident population (severe behavioral challenges) may contribute to this, but families should ask management directly about the specifics and corrective actions taken.
Dementia-only focus
This is a dedicated memory care facility, not a general assisted living home. If your loved one does not have significant cognitive decline, the secured environment and specialized programming may not be the right fit.
Diamond Bar is in eastern LA County
Located in the San Gabriel Valley foothills, Diamond Bar is a considerable drive from central or west LA. Factor in commute time for regular family visits.
