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.

Katherine (Kat) Culberg began her career as a registered nurse and quickly developed a passion for working in public health and social justice.  Her focus has been on impacted, adolescent youth in urban, underserved, under-resourced areas.

Over the last few years, she has studied, trained and participated in restorative justice work resulting in a position with Restorative Justice for Oakland Youth (RJOY) directing the Circles of Support and Accountability Re-entry program in the Alameda County Juvenile Hall.

David Dean is passionate about healing the psychological impact of systemic oppression on youth most vulnerable to its violence, and within people made dominant by it.

He has sought to do this as coordinator of a summer youth activism program called The Unity Hoops Project, as an advocate for restorative discipline in schools, as a facilitator supporting men to overcome hyper-masculine social expectations, and as a writer and trainer for White Awake
