Wickham was raised in a Christian home, the second of three children (brother Evan, sister Jillian), and began leading worship for his youth group at 13 years of age. He graduated from Calvary Christian School in Vista, California, in 2002. Wickham’s father is currently a worship leader, and both of his parents were at one time members of Jesus movement band Parable. His older brother Evan Wickham is also a musician, who used to serve at Calvary Chapel in Vista and later became pastor of Park Hill Church in San Diego, California. His parents, John and Lisa (née Irwin), encouraged Wickham to learn popular praise songs and to write his own. Wickham began his full-time music career by touring California and recording his first album.
