Sorry to hear about this situation. It's very stressful for the whole family, for sure. My dad has frontal lobe dementia and aphasia, and we've gone through the struggles to try to find a suitable place for him. We had in-home care for as long as we could, but it got to a point where the toll it was taking on my mom was too much for her to bear.
We looked at several facilities, most of which had a "memory care" unit. I would definitely suggest looking at multiple facilities, taking a tour, and meeting with the staff, before making any decision. A couple of things to keep in mind as you are reviewing these facilities: staff-to-resident ratio (huge), cost, location, staff training, availability of an on-site nurse, services/activities available, medicare/insurance acceptance, etc. Some of the places we looked at included Aksarben Village, Via Christie, Hillcrest, Brookstone, etc.
We ended up moving him into a small facility (<10 residents) called Compassionate Memory Care. They operate two houses, and generally had two staff members on-site at all times. It was great, until it wasn't. The owner had some health issues, and the staff turnover was pretty high after that. Initially, the care he received there was great, but it deteriorated over time. It was by far the most affordable option, and they were willing to work with Medicare after his long-term care insurance ran out. Unfortunately, we eventually had to move him because the level of care dropped off significantly.
After that, we moved him to a place called Bickford. It was a really nice facility, although quite a bit larger. He had private living quarters, which was great. This issue with this place was that they kind of misrepresented their ability/preparedness to deal with dementia patients. Though it was a secured facility, he ended up escaping several times, and it was in a busy area of town. Not ideal. They were definitely understaffed in terms of dealing with high-need patients. It was a really nice place for basic assisted-living, but the care he received left A LOT to be desired.
Currently, my dad is in the memory care unit at the Douglas County Health Center. I certainly had serious reservations about this place, but couldn't be happier with the services they are able to provide him. It is very secure, and well-staffed. The amount of stress in all of our lives has decreased significantly since moving him here. It is very bare-bones, and nowhere near the fanciest place, but they do a great job with his medications, meals, activities, etc.
I will say, if your family is able to afford it, Brookstone and Aksarben Village are very nice. They are both welcoming environments, and I both have memory care services available. Moving a parent to a facility is a difficult experience, one that can be super frustrating at times. Doing your research ahead of time is absolutely critical, and I would reiterate the importance of visiting several places to see which one seems to fit. If you have any other specific questions, let me know, and I would be happy to help however I can.
