DC has a number of Coder Dojos were you can work with kids as a mentor or volunteer.
Dojos can always use volunteers and mentors for sessions – even if you don’t code! You can join a current dojo, or start your own.
The Coder Dojo Foundation is headquartered in Ireland, but they support Dojos all over the world. You can see a list of Dojos near you at https://zen.coderdojo.com/find.
