A native of Springfield, Ohio, Kirk grew up in a non-Christian home and did not discover a relationship with Christ until he was a young adult. He pursued a career in the construction industry until God pursued Kirk for ministry. He went to Boyce Bible College and entered full-time ministry at Northside Baptist Church in Springfield, where he had been serving as deacon. At Northside, Kirk first served as youth minister before transitioning into the role of associate pastor. He continues to serve Northside as he leads New Day during this interim. Kirk is married to Cindy, and the couple has two adult daughters.
