Companion Care Needed

About who needs care: I'm looking for someone to take my Mom on walks around the neighborhood of her assisted living. She has an Alzheimer's diagnosis but is very high functioning and very physically fit. Walking has been one of her main hobbies, and I'm looking for someone to walk and chat with her on days I am unable to. About the care needs: I'm looking for someone who is physically fit (able to walk 1-2 miles / for an hour) and enjoys chatting with older folks. They should be patient and able to hold a conversation with someone who might repeat stories or questions. My mom has a lot of personality and can be fun to chat with! Services needed include: companionship.
