What is the name of a person who helps in various matters for free?

l think a lot more people should volunteer. they say they feel lonely, depressed and anxious. why not give volunteering a try.

I volunteer at the local Food bank

I volunteered for a cancer organization and collected several gift cards from different businesses. After collecting more than any other volunteer, I was shocked when most of the gift cards were never made available as prizes for the games. The person in charge said she forgot to include them as prizes. Therefore, someone bought hundreds of gift cards for less than $100! I enjoyed the work until then.
