Timothy Keller is Chairman and Co-Founder of Redeemer City to City and Pastor Emeritus Redeemer Presbyterian Church in New York City, which he and his wife, Kathy, started in 1989. For over twenty-five years Tim led a diverse congregation of young professionals that grew to a weekly worshipping community of over 6,000 people, meeting at eight services in three different congregations in Manhattan. In May 2017, those three congregations became independent churches, and Tim transitioned out of his senior pastor role to focus on ministry more broadly in New York City and other global cities through the work of City to City, which has helped start close to 500 churches in 70 global cities. He is the author of such New York Times bestselling books as The Reason for God, The Prodigal God, Every Good Endeavor and The Meaning of Marriage.
