Ramsay Boly is a second-year Burkinabe-American graduate student with the Master of Development Practice. Ramsay’s values and identities draw from a global spectrum of cultures, ideologies, and narratives. Ramsay completed a B.A. in Conflict Analysis and Resolution with a minor in Non-Profit Studies at George Mason University before taking on the entrepreneur lifestyle. Ramsay believes that modern development urgently needs a shift away from identity-based politics and paternalistic practices, that reflects divine interdependence to enable true collaboration. His work towards these goals focuses on self-cultivation, restorative justice, diversity inclusivity, conflict resolution, youth empowerment, social entrepreneurship, and collaborative impact.
