She noted on her official Instagram that "He created light and thought and humor everywhere he went. He was a brilliant actor and director and writer. His students are so lucky they had him as their teacher."Just days before his death, Grisetti left the production of “Legally Blonde” that he was directing in Italy, citing personal reasons. In his final Instagram post, the actor paid tribute to the production, wished them luck on their opening night and described himself as “literally crying” on the plane home. Grisetti previously worked internationally. In a 2016 interview, he encouraged fellow actors to work abroad as much as possible. “Under the right conditions, it's a thrilling way to see the world and experience new cultures while doing what you love. I can't recommend that aspect of an international gig highly enough,” he said. Born in Washington, D.C., and raised in Southwest Virginia, Grisetti earned a Bachelor of Fine Arts from the Boston Conservatory in 2004. His notable stage credits included "It Shoulda Been You" (2015) and "Something Rotten!" on Broadway, as well as a television appearance in "The Marvelous Mrs. Maisel."Grisetti is survived by his wife of six years, Mackenzie, an LA-based realtor.
