Companion Care Needed For My Grandmother In Rockwall

I need a companion care provider for my grandmother in her 90s. Seeking someone to handle her lunch preparation and keep her company on the days I have to work. Duties include providing companionship and social interaction. Preferences for a caregiver who is a non-smoker, comfortable with pets and CPR / first aid trained. She has severe OCD and every day for her must be the same or she becomes stressed. Thank You!
