Seeking Part-time Senior Care Provider In Boston

I need a senior care provider with experience on Wednesdays only. My father is a retired surgeon and my mother and I alternate caring for him at home. On Wednesdays, we are both unable to be home between the hours of 10 a.m. and 6 p.m. due to work commitments. We are looking for someone to check in on my dad and keep him company for a few hours each Wednesday. My dad uses a cane and struggles immensely with mobility. Beyond trips to the bathroom, he needs to be in a wheelchair. Our care concerns are: Mobility Assistance, Help Staying Physically Active, Companionship. Duties include providing companionship and social interaction, encouraging daily supervised walks down the hallway.
