George Barna has filled executive roles in politics, marketing, advertising, media development, research and ministry. He founded the Barna Research Group in 1984 (now The Barna Group) and helped it become a leading marketing research firm focused on the intersection of faith and culture before selling it in 2009. Through the Barna Group, George has served several hundred parachurch ministries, thousands of Christian churches, and many other non-profit and for-profit organizations as well as the U.S. military. He currently serves as the Executive Director of the American Culture and Faith Institute (a division of United in Purpose), and is President of Metaformation, a faith development organization. Barna has written more than 50 books, mostly addressing cultural trends, leadership, spiritual development, and church dynamics. They include New York Times bestsellers and several award-winning books. His works have been translated into more than a dozen foreign languages. He has sold more books based on survey research related to matters of faith than any author in American history. His work is frequently cited as an authoritative source by the media. Barna has been hailed as “the most quoted person in the Christian Church today” and has been named by various media as one of the nation’s most influential Christian leaders. After attending high school and college together, George and his wife Nancy married in 1978. They have three adopted daughters and one grandchild, live on the central California coast, and attend Mission Church in Ventura. He enjoys reading, music, rooting for the Yankees and Lakers, and relaxing on the beach.
