Ron Luce is the president and founder of Teen Mania Ministries, a Christian youth organization that reaches millions of young people worldwide.  Raised in a broken home, Ron ran away at the age of 15 and became involved in drug and alcohol abuse before finding Jesus at the age of 16.  The life-transforming impact of Christ inspired Ron to dedicate his life to reaching young people.  After receiving a bachelor’s degree in Theology and Psychology and a master’s degree in Counseling, Ron and his wife, Katie, started Teen Mania in 1986 with nothing more than a Chevy Citation.  Their dream was to raise up an army of young people who would change the world. As a part of Teen Mania, Ron rallies teens all over the U.S. in arenas and stadiums at events called Acquire the Fire, with over 3 million attendees to date.  Ron appeared as a teen culture expert on CNN God’s Warriors, ABC Nightline, NBC, The Sean Hannity Show, The O’Reilly Factor, 700 Club, and Focus on the Family.  Ron and Katie live in Garden Valley, Texas, with their son Cameron while their two daughters, Hannah and Charity are off at college.
