Senior Caregiver - Full-time / Part-time

I'm looking for companion care for my mother-in-law who is 85, and recently widowed.. Assistance with medication is needed. Duties include providing companionship and social interaction although she has a very busy social schedule. Part of your responsibilities will include running errands. Duties include transportation (doctor's appointments, errands, etc.). Preferences for a caregiver who is a non-smoker and CPR / first-aid trained.
