Why we like it

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.
