Christina’s academic and professional journey has been closely aligned with advocacy and resource allocation, always with a keen awareness of the intersectionality that profoundly impacts individuals and communities.

Dan Medina
Lincoln High School Program Director | He/Him/His
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. He eventually turned his life around, completed his GED, started his own construction company and volunteered as a sports coach. In 1999, Lincoln High School, struggling to reduce gang activity, asked him become the school’s community / attendance liaison and a coach. 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”. In 2006, the YESS Institute piloted its peer-mentoring model at Lincoln HS with Dan Medina serving as the School Liaison for the program.

Desiree is deeply committed to her role, working with youth from Lincoln High School and their families, and making a significant impact across numerous Denver communities. She has led several successful YESS initiatives, including coordinating vital resources for families in need.

Cheyenne Bueno
Program Manager | she/her/hers

Her extensive experience working with at-risk youth in the DYS juvenile system has given her insight into the real-life challenges youth face in Colorado, as well as the impacts of those challenges.

That relationship drives her commitment to creating similar environments for YESS students today.
