How to choose a Medicaid care agency for self-directed care?

Hello fellow caregivers,

I am in the process of choosing a Medicaid care agency for my mom under the Aged and Disabled waiver program. I will be her 24hr in-home caregiver. I have called all the agencies on the provided list and have been able to narrow them down. Since I am going to be employed by the agency, how do I know they will be a good fit for myself and mother? I am about a year into caregiving and I have never worked in health care, so this is all new to me.

Beyond calling, I've researched the agency websites, if any, the forum here, indeed.com, BBB, Google reviews, etc. A lot of these places have very minimal or no info and many seem to have started business in the last year. I've also asked my MIL to ask a friend who could possibly have insight, but I haven't gotten a response yet. Is there anything else I can do to find the right agency besides going off my gut feeling?
