James Misner is committed to building systems that create lasting impact. Growing up near Philadelphia in the 1990s, he was struck by his community’s negative attitudes toward refugees from the Balkans and Rwanda.

After roles in refugee resettlement at Wheaton Bible Church and McLean Bible Church, he spent a decade at World Relief as Senior Vice President of Strategic Engagement, leading partnerships and revenue strategy. Now, as Founder and CEO of The Kipos Group, he helps small and mid-sized nonprofits overcome fundraising barriers and grow sustainably. In this conversation, we explore his journey—from hands-on refugee work to rethinking nonprofit fundraising—beginning in the neighborhood where it all started.
