Companion Care Needed

About who needs care: My dad has type I diabetes and some mobility issues but is otherwise doing well. We are just worried about him being in the cottage by himself and getting up and down the dock. About the care needs: Hopefully they will love lakes and boats. We really need someone who can get to him by boat as it sort of defeats the purpose if he has to walk down the dock and lower himself into a boat to pickthe caregiver up in Cedarville or Hessel. Services needed include: meal preparation, errands / shopping, light housekeeping, and mobility assistance.
