SUPPORT THE NEXT GENERATION OF RETREADERS

The Marvin Bozarth Memorial Scholarship honors the legacy of Marvin Bozarth, a longtime leader, innovator, and advocate in the tire retread and repair industry. With decades of service and a passion for advancing the trade, Marvin played a key role in shaping industry standards and mentoring future generations.

The retread industry remains a vital part of the U.S. economy and environmental efforts, saving end-users millions each year while reducing carbon emissions and conserving natural resources. Like many skilled trades, the industry faces a shortage of new talent, and many students lack the financial resources to pursue vocational education. This scholarship supports current trade school students and high school students planning to enter trade programs focused on transportation or the automotive field.
