Born in Boston, Massachusetts and raised in Phoenix, Arizona, he is one of eight children. Newquist started writing songs at an early age and moved to Los Angeles, California to further his music career. In 1993, he formed Caroline's Spine with college friend Mark Haugh – the band's name being a reference to a character in a story Newquist wrote about a comatose girl whose doctor nonchalantly inquires, "How's Caroline's spine today?"

His major label debut, "Monsoon" by Caroline's Spine, was released by Hollywood Records in 1997. Newquist has since released numerous albums under the Caroline's Spine moniker as well as his own name.
