Companion Care Needed For My Father In Rockville

I'm looking for companion care for my father in his 80s. We need someone who can handle various daily chores, also meal preparation. We might ask you to run errands now and then. Duties include transportation (doctor's appointments, errands, etc.). Must be a non-smoker and comfortable with dogs. My Father is VERY hard of hearing and it is difficult to converse with him. Once he understands, he is agreeable. Looking for a patient companion who speaks English WITHOUT an accent. Currently he takes care of most things himself, his own laundry, makes his bed, showers, dresses, goes to the store, church, some doctor visits and he is still driving. However, as time goes on, some of these things become more difficult. We expect additional needs and longer periods of time as he gets older.
