Companion Care Needed - Full-time / Part-time

I need a care provider for my father (age 91) who is mobile but sometimes unsteady. His mind is sharp and likes to talk and play cards. Schedule days/times flexible but probably 3 half days/wk (again flexible and may increase). Please be willing to do light housekeeping and maybe prepare lunch while visiting. Looking for a caring and compassionate companion. We ask that you handle transportation to appointments as needed. Preferences for a caregiver who is a non-smoker.
