Jonathan serves as the International Director for Asia Pacific with Mission to the World (MTW), the global missions agency of the Presbyterian Church in America (PCA). Based in Japan, he oversees MTW’s missionaries and ministry projects spanning church planting, leadership development, and theological education across the Asia Pacific region. He and his wife Maggie began their missionary service in South Asia, where Jonathan planted and pastored a church in a global city before stepping into his current leadership role. MTW's vision is to plant Reformed and Presbyterian churches among the unreached and least reached peoples of Asia Pacific, a calling Jonathan and Maggie pursue together alongside their six daughters.
