Do you recommend some best home health aide agencies?

Actually, my mom needs a home health aide. She’s in her late 60s and has Multiple sclerosis. My mom falls a lot, she needs 24 hour help and one should always present around her for assistance. We are new to this area. Do you have any advice in hiring someone? Do you recommend some best home health aide agencies? I need solution from any one with noteworthy experiences. My mom is very sociable, so is likely to get along with most people. But she’s very particular about how things are done in her house. If it helps, she’s in Southern Maine. Please help me.
