Companion Care Needed For My Mother In Lexington, MA.

I'm looking for companion care for my mother in her 70s. We need someone who can handle light housekeeping, to include laundry, and provide companionship as well as medication assistance. She needs help with groceries and errands when appropriate. It would be for 5 hours per week. We are flexible on days and times. Must have transportation and be a non-smoker. Preference for caretakers that speak Polish. Preference for close proximity to Lexington.
