He is a founding member of both bands, and has also collaborated with many other artists over the years. His debut solo album, All I Was, will be released in July 2012.

Since his early years with Creed, Tremonti has received positive recognition as a guitarist and songwriter and has received a number of accolades, including one Grammy Award for Creed's single "With Arms Wide Open."

Tremonti was born on April 18, 1974, in Detroit, Michigan. He grew up in a Roman Catholic family in Grosse Pointe, just outside of Detroit, for most of his childhood life before moving to Wilmette, Illinois. Around this time, he began to become enthralled with music, and bought his first guitar at the age of eleven. When he was fifteen, his family moved again to Orlando, Florida, where he enrolled in Lake Highland Preparatory School. During this time, his mother was diagnosed with systemic lupus erythematosus, which left Tremonti devastated. After graduation, he moved to Clemson, South Carolina to attend Clemson University to major in finance. After his freshman year in college, he moved back to Florida to enroll in Florida State University, where he was reunited with his then future Creed band mate Scott Stapp, whom Tremonti had known in high school.
