Senior Caregiver

I'm looking for companion care for my father in his 80s. We're looking for someone to provide companionship. Preferences for a caregiver who is a non-smoker and CPR / first-aid trained. We already have 24/7 caregivers in the home for both my mother, who has Dementia, and also my father. However, my father needs a male that he can conversate with and also for assistance in mobility. He is a fall risk. Ideally, we would want this person in the home from early morning (7 a.m. or 8am) to late afternoon or early evening.
