Billy Coppedge and his wife Joanna met at Asbury University. They then studied together at Wesley Biblical Seminary before God called them to live and serve in northern Uganda for seven years.

Out of working alongside national church leaders in both Uganda and South Sudan, Billy came to realize the power of oral methodologies for communicating the gospel, whether in theological training, community development, or witnessing to one’s neighbor.

Billy believes the legitimacy of harnessing oral strategies for communicating God’s word throughout the world rests in God desiring to be known. The primary way God brings transformation in the human heart is through engagement in his Word, both in the person of Jesus Christ and his Scriptures. Billy's passion is to help others experience such engagement through whichever communication method necessary, so they can experience the transformation of knowing Jesus.
