Darreyel Laster is a native of Pensacola, Florida and a 10 year veteran in education. He began his educational career as a middle school literature teacher on Chicago’s southside. While in the classroom, Mr. Laster developed his zeal for teaching which molded him into a dedicated and passionate purveyor of social justice, global citizenship, and equity– especially for those from marginalized and disenfranchised communities.  

After five successful years in the classroom, Mr. Laster  joined a group of four other educators to plan and launch pilotED Schools, an emerging social identity-centered charter school network. pilotED Schools believes school-aged children living in urban environments need to be afforded the opportunity to explore topics such as race, gender, class, and other social issues in an effort to develop academic success and lasting civic engagement mindsets. 

In 2021, Darreyel moved back home to Pensacola to serve the under-resourced  Warrington community. Currently, he is the Administrative Dean of Warrington Middle School and the CEO of Equity by Design, a burgeoning creative hub that supports individuals and institutions to facilitate transformative change in order to become more equitable and inclusive.
