Dementia Care Needed For My Wife In Cumming

I need a companion care provider with Alzheimer's / Dementia experience for my wife who is 60. She also has very limited vision and requires significant guidance, and creativity in finding ways to pass the time (cannot read or write). Additional responsibilities include meal preparation, going for walks, etc. Looking for a very patient, caring, and compassionate companion. Preferences for a caregiver who is a non-smoker and comfortable with pets.
