Barry, a graduate of Christ for the Nations Institute in Dallas, Texas, has been serving the Lord since 1972. He and his wife, Betty Kay, have served on the mission field in Mexico, Guatemala, and in Chile, where they spent almost 12 years before returning to Texas in 2001.

While attending a large Spanish-speaking congregation in Carrollton, Texas, Barry was the director and principal teacher at a Spanish language Bible institute, Instituto Avance, where he served for five years. The Bennetts also spent two and a half years ministering to Cambodian refugees in Dallas, and they have ministered in home groups, churches, and on short-term mission teams.

Barry came to Andrew Wommack Ministries in 2007 and worked in the Phone Center as a prayer minister before accepting a position answering the scriptural and doctrinal questions that would come to AWMI via mail and email. He later went on to be the Dean of Students, and is now the Dean of Instructors. Barry is also an instructor at Charis Bible College in Colorado and teaches at both domestic and international CBC satellite campuses.
