MEET THE TEAM

Rev. Adrian De Visser

Currently serves as the International Deputy Director for South Asia and is also the Founder and Senior Pastor of Kithu Sevana Ministries based in Sri Lanka. Adrian entered Christian Ministry in 1979 as the first local-language ministry worker for Youth For Christ, Sri   Lanka. His work took him to remote and marginalised communities and gave him a deep conviction and passion for reaching them for Christ. In 1993, he founded Kithu Sevana Ministries, a missions-oriented church planting organisation with a burden for reaching those in areas and communities hitherto unreached by the gospel. Kithu Sevana follows the concept of a distributed church, and strongly believes in partnering with Churches and Christian ministries across Asia and in developing and empowering local leaders for ministry.

Adrian holds an MA in Missions from Columbia International University, and was awarded an honorary doctorate by the Government of Sri Lanka in 2007 for his social development and community-oriented work of over two decades. In the same year, he was also awarded the title of Deshabandu by the Government of Sri Lanka, one of Sri Lanka’s highest civilian honors, for his work amongst the poor in Sri Lanka. Adrian is also the Vice President for Partnership Development for Asian Access and a Member of the Governing Board of the Colombo Theological Seminary, Sri Lanka and formerly served as the International Deputy Director for South Asia for the Lausanne Committee for World Evangelisation
