Mark Mittelberg is a best-selling author, sought-after speaker, and a leading strategist in evangelism and apologetics-oriented outreach. He is the primary creator (with Lee Strobel and Bill Hybels) the Becoming a Contagious Christian Training Course, which has been translated into more than 20 languages and used to train 1.5 million people around the world to effectively and naturally communicate their faith to others.

Mark has written several books, including The Questions Christians Hope No One Will Ask, Choosing Your Faith, and The Reason Why Faith Makes Sense. Mark collaborated with Lee Strobel to develop The Unexpected Adventure, a six-week devotional designed to inspire Christians and churches to enter into the excitement of sharing Christ. In addition, Mark was a contributor to God Is Great, God Is Good: Why Believing in God Is Reasonable & Responsible, edited by William Lane Craig and Chad Meister — which won the 2010 Christianity Today award for best book in the area of apologetics and evangelism.
 
Mark was the evangelism director at Willow Creek Community Church in Chicago for seven years and for the Willow Creek Association for a decade. He is a frequent contributor for Outreach magazine, and he was an editorial consultant and periodic guest for Lee Strobel’s Faith Under Fire television show. He and Strobel have been ministry partners for over twenty years. Together they co-direct The Institute at Cherry Hills in Denver, Colorado.
 
After receiving an undergraduate degree in business, Mark earned a Master's Degree in Philosophy of Religion from Trinity Evangelical Divinity School in Deerfield, Illinois. In recognition of his achievements in the areas of evangelism and apologetics, he was recently honored by the conferring of a Doctor of Divinity degree from Southern Evangelical Seminary in Charlotte, North Carolina. 

"Our event with Mark was wonderful. We had over 400 people come out to hear Mark speak and he did a terrific job. So many people have expressed appreciation for his teaching and I believe God is really going to use that night to help people overcome their fear of sharing their faith. We'd definitely do it again." - Outreach Pastor, Rolling Hills Covenant Church
