Companion Care Needed - Care.com : Job Details

My 83-year-old father has Altzheimers, moderate stage. He just moved from the St. Louis area to live with me, his daughter. We had 2-4 hours of care when he lived independently and expect to need to same. I still work, albeit from home. We are looking for a companion for walking, activities (a trip to library, etc), problem solving (crossword puzzles, fixing things etc). He needs prompting to stay on task. We're looking for a bright, smile-ready, agreeable person.
