Sam Caster has always had a heart for leadership, intercultural understanding, and humanitarian outreach. After founding a network marketing company based in Texas, he recently transitioned his business into a social entrepreneurship model by integrating giving as a core component to their mission. He recently rallied his associates around a movement he calls Mission 5 Million, linking 5 million consumers with 5 million children in need. At a recent symposium on social enterprise, Sam had a chance to share his vision with Vicente Fox and Dr. Muhammad Yunus.
