Harrison Leahy began performing professionally at just 9 years old, when he was cast as CHIP in the International Broadway Tour of Beauty and the Beast, working under the direction of original Broadway director Rob Roth. At age 10, he joined the National Broadway Tour of Pippin in the role of THEO, again collaborating with the original Broadway creative team. By the age of 11, Harrison had traveled nearly 70,000 miles across the U.S. and internationally as part of these acclaimed productions-gaining extensive theater and vocal experience at a young age.

Shortly after, Harrison and his family relocated from South Carolina to Los Angeles to pursue opportunities in film and television. He became SAG-Eligible after booking the lead role in the Lifetime movie He's Watching, and officially joined the Screen Actors Guild at age 12. His early work includes leading roles for Bravo TV Online, Sony Entertainment Studios, a national SAG commercial for TurboTax, and educational programming. He has also appeared as a co-star on major network series such as The Goldbergs, Perfect Harmony, NCIS, and L.A.'s Finest.

In 2025, Harrison booked a recurring guest star role as Young Alden Parker on NCIS and a co-star role on the Untitled Steve Carell Project, further expanding his network television credits.

Graduating in the top 10% of his class at John Burroughs Highschool with a GPA exceeding 4.0, Harrison now studies TV & Film Production with a focus on Directing at Chapman University's renowned Dodge College of Film and Media Arts-selected as one of just 20 directing students in his class. He remains on the university's Provost List, maintaining a GPA of 3.8 or higher.

Now a proud member of the Phi Delta Theta fraternity, Harrison is also active in philanthropy through their partnership with the "Live Like Lou Foundation." Passionate about storytelling, he enjoys developing original characters inspired by real life and is committed to building a dynamic body of work across both comedy and drama over the course of his career.
