Pastor Dennis Leatherman grew up in Harleysville, Pa, a small town just north of Philadelphia. Though his teenage years were characterized by extreme rebellion, drug addiction, and general debauchery, the influence and testimony of his Godly father carried a powerful impact and Brother Leatherman trusted Jesus Christ as his personal Savior at the age of nineteen. His life was immediately and drastically transformed by the power of the Gospel.
Shortly after his salvation, Brother Leatherman enrolled in Philadelphia College of the Bible. After one year, he transferred to Tennessee Temple University and graduated in 1986. The following year he married Kathy Shiflet (from Richwood, WV) whom he met working in the bus ministry while in college.

In 2006, Brother Leatherman was presented an Honorary Doctorate by the Northeast Baptist School of Theology in Downingtown, PA. Brother Leatherman's sermons are regularly featured on the Fundamental Broadcasting Network's "Selected Programming" feature and has had a number of sermons printed in the Sword of the Lord newspaper.
