Frank and Ida Mae Hammond were both brought up in solid Christian homes in eastern Texas. Frank, an ordained Baptist minister, held an A.B. degree from Baylor University and a B.D. degree from Southwestern Baptist Theological Seminary in Ft. Worth. Ida Mae attended East Texas Baptist College and Southwestern Seminary. Frank and Ida Mae engaged in pastoral ministry for over thirty years.

​

The Hammonds found their ministry taking on new depths and direction after experiencing the baptism in the Holy Spirit. They traveled extensively throughout the United States and abroad, ministering with a major emphasis in the area of deliverance. They have authored numerous books and Audio CDs on the topic of deliverance, including Pigs in the Parlor, Overcoming Rejection, Breaking of Curses, Manual for Children's Deliverance, Demons & Deliverance in the Ministry of Jesus, and more.

They were truly pioneers in the field of deliverance, and in the modern day ministry of Jesus Christ in the casting out of demons.
