From 2004-2014, Case Western Reserve University housed The Treu-Mart Youth Development Fellowship Program, a capacity-building initiative aimed at increasing the ability of youth-serving organizations in Cuyahoga County to attain positive outcomes for the youth they serve. The Fellowship provided professional development and supports based on research and best/promising practices for those who work with youth during non-school hours. Programming was framed by concepts of resiliency, positive youth development and resonant leadership. Approximately 150 individuals completed Fellowship program—sponsored by nearly 100 organizations/organization sites. Major funding for the Fellowship Program was provided by the Treu-Mart Fund—a supporting organization of the Cleveland Foundation and the Jewish Community Federation of Cleveland. Treu-Mart Fellows continue to impact the youth development field in Cuyahoga County, both through leadership and direct service roles.
