Paul and Roxanne labor to catalyze churches among unreached people groups in Central Asia. Paul is an ethnomusicologist and works with local musicians to create indigenous hymnody that uses traditional instruments, musical styles, and poetic forms that enable the gospel to be communicated in the heart language of each ethnic group. He also teaches and mentors Christian musicians who are active in church planting- Roxanne partners in this work through her administrative gifts and spiritual mentorship to women.
