Leadership
David Bogosian
Director, A Third of Us Alliance
David brings decades of experience in global mission leadership and collaboration. He served ten years in Asia with Frontier Mission Fellowship and contributed to strategic initiatives at the U.S. Center for World Mission, including the Adopt-A-People Campaign and research on unreached peoples. David also co-founded Light the Window, a social-media prayer movement highlighting the largest least-reached groups in the 10/40 Window.
For the past seven years, David has led Christian Aid Mission as President/CEO, championing efforts to equip near-cultural workers to reach the last frontiers of the gospel. His passion for partnership has shaped networks such as the Africa Mission Association, COSIM, and the Global Council of Mission. A graduate of Biola University and WCIU with a focus in missiology, David continues to advocate for collaboration as a key to fulfilling the Great Commission.
