Key Review Excerpts

The two CNA's that really work with my sister well are Maria and Alesa. I know when they have worked with my and my sister just from my sister's appearance. I also noticed they greet my sister when they are working with her and talk to her although my sister can't talk but they always let me know when she responds to them.

Long-term resident's family · 2025★★★★★

I was thoroughly impressed by the new high- tech registration system for visitors which uses facial recognition to check visitors in, and prints a visitor's pass all in mere seconds.
