Our International Team

David serves as Professor of Old Testament and Biblical Languages at the Biblical Seminary of Colombia. He and his wife, Karen, work from dual ministry bases, spending half of each year near Hartford, Connecticut, USA and the other half in Colombia’s beguiling second city of Medellín. David and Karen have six adult children and eleven grand-children. David was born and raised in a small Pennsylvania German town amid rolling farmland between Appalachian ridges and still feels rooted in that same modestly magnificent valley. Yet the Lord’s calling on his life has taken him far from there in support of Majority-World theological education and those who shape it and are formed by it. He served for a dozen years as the president of Overseas Council (USA) and so is no stranger to the Overseas Council Network, of which reSource Leadership International is a key member.

Mariel is a native Argentine who together with her husband Steve Voth, lives in Buenos Aires, Argentina. She has spent a lifetime in the world of Theological Education and is a qualified Theological Librarian. She is highly respected across Latin America and the Caribbean and is a regular facilitator at the Institutes for Excellence held throughout that region of the world.

Daniel (BA, Wheaton College; MDiv, Trinity Evangelical Divinity School, PhD, Wheaton College) is our Regional Consultant for Vietnam. He has been involved in ministry in Vietnam for more than twenty years. Prior to his pastoral current role at New Covenant Church in Naperville, Illinois, USA, he taught at Hanoi Bible College and Singapore Bible College. Although primarily focused on the ministry of New Covenant Church, he continues to be a resource for Hanoi Bible College, to write for Vietnamese-speaking Christian readers, and periodically to teach Old Testament courses in Vietnamese online. He is married to Heather and they have two teenage sons.
