Broadway Actor and CSU Fullerton Professor Josh Grisetti Dies at Age 44

Grisetti’s breakout came Off-Broadway with Enter Laughing at the York Theatre in 2008, where he earned the Theatre World Award for Outstanding Debut Performance and drew Drama Desk and Outer Critics Circle nominations.
His Broadway debut was anticipated in the Neil Simon revival Broadway Bound, but the production was canceled before its premiere, altering the trajectory of his Broadway path.
In recent years, Grisetti took on notable regional and touring roles, including Tateh in Ragtime at La Mirada Theatre (2023) and Sheldon J. Plankton in SpongeBob Squarepants the Musical (2024) for Broadway Sacramento.
On the directing side, Grisetti was involved with Legally Blonde at the Trentino Music Festival, stepping away from the production before its opening night.
Broadway actor and educator Josh Grisetti died by suicide on July 10 at age 44, according to People. Friends confirmed the news on social media, mourning the loss of a performer known for his work in Something Rotten!, It Shoulda Been You, and The Marvelous Mrs. Maisel. He is survived by his wife, Mackenzie Grisetti.
Grisetti was also a beloved teacher. He served as head of the BFA Musical Theatre program at California State University Fullerton, where colleagues say he had a deep impact on students. Co-stars Sierra Boggess and Rob McClure both shared public tributes praising his talent and his dedication to the next generation of performers.
Grisetti was born in 1981 in Washington, D.C., and grew up in Rocky Mount, Virginia. He trained at the North Carolina School of the Arts and the Boston Conservatory, earning a BFA in Musical Theatre in 2004. His career spanned Broadway, national tours, regional theater, and television, according to People.
On Broadway, he appeared in Something Rotten! and It Shoulda Been You. On screen, he landed a recurring role in The Marvelous Mrs. Maisel. His stage work also included Camelot and regional productions well into the 2020s, showing a career that stayed active and wide-ranging right up to his death.
Grisetti's big break came in 2008. He starred Off-Broadway in Enter Laughing at the York Theatre and earned the Theatre World Award for Outstanding Debut Performance. The role also drew Drama Desk and Outer Critics Circle nominations — a remarkable haul for a debut, according to Newsy Today.
His Broadway debut was nearly a Neil Simon revival called Broadway Bound. But the production was canceled before it ever opened. That setback changed the path of his Broadway career, though it did not slow him down for long.
In his final years, Grisetti kept taking on bold roles. In 2023, he played Tateh in Ragtime at La Mirada Theatre. In 2024, he took on the comedic villain Sheldon J. Plankton in SpongeBob Squarepants the Musical for Broadway Sacramento, according to Newsy Today.
He also moved into directing. He was involved with a production of Legally Blonde at the Trentino Music Festival, though he stepped away from the project before opening night. His work as both a performer and a director showed the breadth of his gifts in the theater world.
The theater world reacted quickly to the news of Grisetti's death. Sierra Boggess and Rob McClure, both well-known Broadway performers, posted tributes online. They praised not just his talent on stage but also his commitment to his students at CSU Fullerton, according to People.
