Bruno Mars moved to Los Angeles in 2003 to pursue a career in music.
Mars left Hawaii after graduating from President Theodore Roosevelt High School in Honolulu. At the time, he was about 17 years old and had already built valuable performance experience through childhood appearances and local work. Los Angeles offered access to professional studios, songwriters, producers, and the broader American music industry.
The move was a major transition. Mars initially worked to establish himself as a songwriter and producer rather than immediately becoming a solo pop star. He co-founded the production and songwriting team the Smeezingtons with Philip Lawrence and Ari Levine, contributing to songs for other performers before his own breakthrough.
Mars’s public profile later changed dramatically after the release of his debut album, Doo-Wops & Hooligans, in 2010. Its singles “Just the Way You Are,” “Grenade,” and “The Lazy Song” turned him into an international star. Some biographies describe the move simply as happening after high school, but 2003 is the commonly cited year.
