Stanford Health Care has a long and proud tradition of volunteer services. We like to recognize and honor our volunteers who contribute valuable hours to our patients, families and staff. National Volunteer Week: Each year we celebrate our volunteers during the National Volunteer Week (usually in April). It is a time to celebrate people doing extraordinary things through service. Volunteer Appreciation Tea: Each year we celebrate our volunteers during our annual Appreciation Tea. Our volunteers are ambassadors and we want to say thanks to each of you.
