Pastor Miller was born in Canton, Ohio, but considers Chandler, Arizona, to be his hometown. He distinctly remembers accepting the Lord as his Savior at age 6: “I was on top of my bunk bed, wearing Mickey Mouse pajamas. I had just spent a week at day camp. A message from camp held onto my heart, and I knew I needed to ask Jesus to be my Savior. So, right there in my bed I prayed and asked the Lord to save me from my sins.” This experience undoubtedly influenced Bryan’s later decision to work in children’s ministry. He received a B.A. in Pastoral Studies from International Baptist College and Seminary and became Children’s Pastor at Tri-City Baptist Church in 1996, though he had already been serving in their children’s ministry for ten years.
