While ministering in Korea, Tim and Moon Sook developed a heart to serve the Church in Asia and received a call to Cambodia. With 50 percent of Cambodians under 21, workers are needed to teach, train, and mentor them to become Christian leaders.

Tim immigrated to the U.S. when his father accepted a pastorate in San Francisco. As a youth he was rebellious but came to faith in Christ during college. After receiving his B.A. at UC Berkeley and M. Div. at Westminster Theological Seminary, Tim was ordained a PCA teaching elder. In 2003, he went to Calvin Seminary in South Korea to teach and establish a theological education program.

Moon Sook was the first to attend church in her family, often gathering friends to join her. She graduated from Young Nam University (South Korea) and became a teacher. Tim met Moon Sook in Korea and they married in 2005.

Tim and Moon Sook decided to follow Christ to Cambodia and serve in the area of theological education by producing theological curriculum for Asian contexts, teaching in Bible schools, discipling leaders, and supporting national churches. They also hope to develop vocational outreach ministries through Korean or English teaching.
