An Atlanta native, Stanfill began playing music at 13, leading worship for his home church throughout high school. After graduating college in 2002, he started leading worship at North Point Community Church in Alpharetta, GA. It was there he met Louie Giglio, who, in the fall of 2004, asked Stanfill to lead worship for 7:22, a popular weekly young adult gathering Giglio established in 1995. In 2005, he became actively involved with the Passion movement, first leading a community group at Passion ‘05, a conference for university students, then as a lead worshipper at Passion ‘06. In 2008 he led at both Passion Regionals USA and on the Passion World Tour.
