Companion Care Needed For My Father In Brookline

I need an experienced care provider and house helper for my father in his 80s and his wife who is his primary caretaker. He is just post back surgery and about to be discharged from the hospital and she is recovering from a knee injury. We live in a three-story house so candidates need the physical capacity to navigate stairs while carrying items and supporting his mobility/balance as needed. Assistance with medical device cleaning is needed. Please be willing to do light housekeeping. Additional responsibilities may include meal preparation, handling groceries or errands when appropriate. Duties may include transportation (doctor's appointments, errands, etc.). Preferences for a caregiver who is a non-smoker, comfortable with pets and CPR / first-aid trained. We have an adorable small dog and may need help with basic feeding and walks.
