Glenn and Sally Clark are non-traditional missionaries. Their home base is in Roanoke, Virginia, but they spend much of their time working with worldwide missions. In 2000 Glenn closed the family construction business in order to follow God's call to fulltime missions work. Glenn had the desire to prepare for ministry, so he spent the next four years earning a degree in theology and becoming an ordained minister. During those four years he did extensive missionary work in many countries. Several years later Sally closed the small Christian school she founded.
Since then they have led work teams from all over the United States to complete projects in Mexico, Cuba, Kenya, and Zambia, as well as in the United States. The teams have worked on orphanages, churches, and parsonages, as well as taking humanitarian aid to people in need and holding evangelistic outreaches to present the Gospel. Glenn has led evangelism conferences for pastors and lay people in Democratic Republic of Congo, Zambia, and Kenya on the continent of Africa. He has also enjoyed taking the hope of Jesus Christ through preaching and teaching evangelism in Peru, Cuba, India, and Mexico.
Glenn and Sally are members of a leadership team for ministry in Nairobi, Kenya. In addition to staffing a missionary guesthouse in the suburbs of the capital city, this team ministers in two of the world's largest slums. Their slum ministry consists of witnessing to the thousands of unsaved people, as well as providing discipleship material for those who make decisions for Jesus Christ. Partnering with several Kenyan pastors, the team has planted churches, established Bible colleges, and brought hope to the hurting.
