Keller is a graduate of Bucknell University, Gordon-Conwell Theological Seminary and Westminster Theological Seminary, under the supervision of Harvie M. Conn. He became a Christian while at Bucknell University, due to the ministry of InterVarsity Christian Fellowship, with which he later served as a staff member. He was ordained by the Presbyterian Church in America (PCA) and served as a pastor at West Hopewell Presbyterian Church in Hopewell, Virginia for nine years, while serving as director of church planting for the PCA. Timothy also served on the faculty of Westminster Theological Seminary, in Philadelphia, Pennsylvania, where he and his wife Kathy Keller were involved in urban ministry. Keller was recruited by his denomination to start Redeemer Presbyterian Church in Manhattan in 1989 despite his relative lack of experience after two others had turned down the position. Today, the church's attendance is over 2,000 each week. (+info)
