Community Highlight
Jeff Winchester is a middle school counselor just outside of San Diego, California. In 2024, he launched CrossFit La Presa — a nonprofit school affiliate created with full support from his district and school leadership.
La Presa Middle School serves a largely underserved community, where many students face challenges outside the classroom. For Jeff, this program isn’t just about fitness — it’s about offering strength, structure, and connection to kids who need it most.
The results are powerful: students are gaining confidence, teachers are rediscovering their health, and kids who once stayed on the sidelines are now trying out for sports. Jeff says launching CrossFit La Presa has been one of the most meaningful moments of his 15-year career in education.⠀
