Dan Medina, Program Manager

Daniel dropped out of Lincoln High School as a freshman, became gang-involved and ran away from home. He was married by age 18 and by 30 he had six children.

Daniel searched the streets to bring the non-attending kids back to school, placed negative peer leaders in small alternative schools and increased parent involvement. His hands-on model combined with the street-credibility earned as a result of his background has helped him connect with and help turn around many “lost kids”.
