Example- I used to volunteer for Habitat for Humanity on Saturday mornings.
Funny you mentioned Habitat for Humanity. I was looking for ways to GAL and have some experience with construction work. I'm going to look into volunteering for HFH to keep busy!
I definitely recommend it, they have something for anyone to do regardless of skill level but if you have construction background then so much the better. There is a misconception that we build "free" houses for undeserving people, but in fact the people buy the houses, they don't get them for nothing. They have to go through a lengthy prequalification process. They have to be employed, but make under a certain income level. They aren't deadbeats, they are people who are genuinely trying to make a life for themselves but struggle with low income jobs and kids to feed. In addition, they have to work on the house themselves, HFH calls it "sweat equity". They have to put in a minimum number of volunteer hours on their house and others in order to qualify to complete the transaction.
You'll make a lot of new friends too. It's a fantastic GAL opportunity.
