My family and I have recently been the recipients of a wonderful volunteer service based in the Napa Valley called Molly's Angels.
Molly's Angels is staffed by volunteers who drive clients to medical appointments in the area - at no charge. This service is a pure gift to family members who live outside the Napa Valley but have a loved one who needs transportation to medical appointments from time to time.
They are cheerful, organized, reliable and are currently accepting new volunteer drivers and charitable contributions. I can't say enough good things about Molly's Angels and their dispatcher, Nicole.
