Hands-on Care Needed For My Father In Casa Grande

About who needs care: My Dad has Parkinson's Disease, Alzheimer's, Dementia. He was a High School teacher for 35 years (space and environmental science, as well as physics and chemistry). He used to own and operate a mobile home park in this same town where he lives (and where he was born and raised). He also helped his mother run the Sunset Court Motel and Service Station until her death in the 1980's (which she and her husband - my GrandDad - built entirely on their own in 1929). Services needed include: meal preparation, errands / shopping, light housekeeping, and mobility assistance.
