Companion Care Needed For My Mother In Lafayette

About who needs care: Our mother has experienced a minor stroke but is still is basically good health. Does not drive but manages cooking and self-care generally well (does have a house cleaner). We are looking for occasional help to relieve my sister who lives in Boulder. My mother is an avid classical music lover, a former painter, violinist and craftswoman, extremely intelligent. She lives in her own condo in Lafayette. About the care needs: A lively, articulate but calm personality would work well with my mother. A love of classical music and movies would also be great! She manages things generally well, but my sister would like to be able to call on additional helpers if/when my mother has occasional back issues and can't cook so easily for herself or get to appointments. Services needed include: transportation, meal preparation, errands / shopping, light housekeeping, and companionship.
