John Ortberg was born in Rockford, Illinois. He earned his undergraduate degree from Wheaton College, and his M.Div. and Ph.D. in clinical psychology from Fuller Theological Seminary. He has also studied at the University of Aberdeen, Scotland. From 1985 to 1990 he served as senior pastor at Simi Valley Community Church, and then from 1990 to 1994 at Horizons Community Church (now Baseline Community Church) in Claremont, California. He then moved from California to Illinois to serve as a teaching pastor at Willow Creek Community Church in South Barrington, Illinois until 2003, when he became the senior pastor at Menlo Park Presbyterian Church, a multi-campus church in Northern California. Now, John leads the ministry Become New focused on helping people grow spiritually one day at a time through daily teaching and community. 

John's wife, Nancy, is also a pastor and published author. She currently leads Transforming the Bay with Christ in San Jose, California. John and Nancy have three children: Laura, Daniel, and John III. 

A central theme of John’s teaching is spiritual formation, the transforming of human character through authentic experiences with God. John was a friend and mentee of the late Dallas Willard, a Christian teacher and author who wrote works such as The Divine Conspiracy and Renovation of the Heart. John draws much of his inspiration from Dallas. Today John continues to work alongside authors and teachers such as John Mark Comer, the founder and leader of Practicing the Way.

John has been a speaker at many events including: Promise Keepers, Global Leadership Summit, Catalyst, and Practicing the Way.

John is currently working on a new book based on the Become New teaching series “Ashes to Beauty” in which he explores the importance of embracing personal inadequacy as a means to experience spiritual renewal.
