Companion Care Needed For My Wife In Huntington Station

I am looking for a part-time companion for my 77-year-old wife who has developed dementia due to Alzheimer's disease. Fortunately, she has no chronic illness currently. She mostly needs assistance preparing her lunch and operating the TV. Companionship is important. She enjoys short walks in the neighborhood. I am usually around but need a little respite from my caregiver duties. Ideally, I would like someone three days a week [M-W-F) from 10 a.m. to 3 p.m. I can be a little flexible if necessary.
