Our Progams in action
Real change happens in the classroom.
Every day, YESS students step into leadership roles, support their peers, and build the confidence to shape their own future. Through peer mentoring and social-emotional learning, classrooms become communities where students learn to lead, connect, and grow.
Because when students believe in themselves, everything changes.

About Dan
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”. Daniel shares his expertise of three decades in his book “The Medina Method”.

About Gabby
Gabriella is passionate about working with youth and making positive impacts on their lives; she finds it incredibly rewarding to see students grow and succeed, knowing that she played a part in their journey.
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. Gabriella was inspired to pursue this career field because of a supportive teacher who made her feel safe and valued when she was younger. That relationship drives her commitment to creating similar environments for YESS students today.
Gabriella is currently attending school to become a social worker, with plans to begin the Social Work program at Metro State. Her favorite extracurriculars include hiking and playing softball. She also coaches middle school athletics whenever she has the chance.
