Sellerdoor is a community marketplace for skateboarders.

SkateMD is a Northern California based 501(c)(3) non-profit organization with a mission to heal hearts by spreading kindness and skateboarding to special populations of children facing developmental, physical, emotional or family challenges. We serve children who may not otherwise be able to pursue skateboarding, don't have easy access to skateboard equipment or facilities, and/or those who just need some extra kindness in their lives. ​Depending on the clinic, we may prioritize children with special needs, ​foster youth, or other at-risk children.
