News of Grisetti’s death comes just days after he announced he’d stepped away from a production of “Legally Blonde: The Musical” that he’d been slated to direct for Italy’s Trentino Music Festival due to “personal reasons.” In a group photo, the show’s cast held up a cell phone showing Grisetti’s headshot to signify him being a part of the company, which he subsequently shared on Instagram in what turned out to be his final post. “Literally cried on the plane… little gestures go a long way when your heart is hurting...” he wrote. “Love this group of misfits right back!!”A native of Washington, D.C., Grisetti grew up in Rocky Mount, Virginia. The youngest of three children, he attended North Carolina School of the Arts and, later, Boston Conservatory, graduating from the latter in 2004 with a bachelor’s degree in musical theater, according to Playbill. In 2008, he made his off-Broadway debut in the musical “Enter Laughing,” winning a Theatre World Award for Outstanding Debut Performance as well as Drama Desk, Outer Critics Circle, Lucille Lortel and Drama League Award nominations.Grisetti made his Broadway debut in the 2015 musical "It Shoulda Been You."

A year later, he joined the cast of Broadway’s “Something Rotten!” in the role of Nigel Bottom, and would go on to reprise the role on the musical’s national tour. In recent years, Grisetti had shifted his focus to arts education and worked as an associate professor of theater and dance at California State University. In 2023, however, he made a high-profile return to acting when he joined the cast of “The Marvelous Mrs. Maisel” in the recurring role of Ralph for the show’s fifth and final season.“To be able to walk that walk and then tell students about that journey and guide them and take away the mystique is important to me,” he told the Orange County Register in 2023 about balancing his acting and higher education careers. “A lot of acting and theater graduates are uninformed or fully lost in how the industry works and don’t do well and get overwhelmed immediately, and I don’t want that to happen to my students.” Of “The Marvelous Mrs. Maisel,” he added, “It’s one of the smartest and best-run shows on television. It has a beautiful balance of taking the work very seriously and creating incredible stuff while also remaining playful so it doesn’t feel oppressive.”If you or someone you know needs help, call or text 988 or chat 988lifeline.org for mental health support.
