Companion Care Needed For My Mother In Menlo Park

I'm looking for visiting care (short check-ins anywhere from 1/2 to 2 hours) for my mother in her 80s who is very independent but having memory problems. You would confirm she has taken her medication, that she's doing well, and provide her some companionship. Part of your responsibilities may include driving her on errands such as the grocery store, shopping, etc if she needs something that day. Must be a non-smoker and English as your first language. College education preferred.
