Don Hellison (1938-2018) developed the Teaching Personal and Social Responsibility (TPSR) model and co-founded the TPSR Alliance. He was committed to teaching transferable life skills and values through physical activity. He truly epitomized the spirit, energy, and conviction of a trailblazer. Today, his work continues to have a significant impact on the fields of physical education and sport-based youth development. Don worked primarily with adolescents growing up in marginalized communities and harsh inner-city environments. He traveled extensively across the United States and across the world teaching as a professor and a lecturer helping educators to learn his unique physical education philosophy.
