Bishop Billy & Sis. Betty McCool – Bishop McCool is the founding pastor of First Apostolic Church. Bishop McCool met Sis. McCool at a tent meeting. They were later married in 1956, and they immediately evangelized the country. In 1957, Bishop and Sis. McCool came to Knoxville with a dream of a church, Christian school, and child care center. They have seen this dream fulfilled and have been the facilitator of many daughter works, such as Eagle Bend Apostolic Church, Clinton, TN, and First Apostolic Church, Maryville, TN. They both still oversee and serve First Apostolic Church Knoxville in a great capacity with their dynamic teaching and passionate leadership.
