Companion Care Needed - Full-time / Part-time

Seeking hands-on care 2-3 days a week (morning/afternoon) in Greensburg for my father, who is 76 and lives with his girlfriend (who does not need help). We would prefer someone who can handle light housekeeping. Seeking someone to handle meal preparation and getting him drinks/food as needed. Duties include providing companionship and social interaction. Preferences for a caregiver who is a non-smoker and CPR / first-aid trained. May need help with getting in and out of the chair at times. He is having some memory issues, so experience with that would be preferred.
