In the early 2000s, Erik Per Sullivan became a household name thanks to his unforgettable role as Dewey, the quirky and often underestimated youngest brother on the hit sitcom Malcolm in the Middle. While many child actors struggle to find footing in Hollywood beyond their early fame, Sullivan chose a different path—one of privacy and quiet retreat. As of 2025, Erik Per Sullivan’s net worth is estimated at $5 million, a figure built during his short yet impactful acting career.
Early Life and Education
Born on July 12, 1991, in Worcester, Massachusetts, Erik is now 33 years old. He is the only child of Fred Sullivan, an Irish-American who owns a local Mexican restaurant called The Alamo, and Ann Sullivan, a native of Sweden. With dual heritage, Erik grew up bilingual and made frequent visits to Sweden during his childhood.
From a young age, Sullivan was a multifaceted talent. He studied both the piano and saxophone, showcasing early artistic inclinations, and also earned a black belt in Taekwondo—a testament to his discipline and focus. For his academic education, he attended Mount Saint Charles Academy in Rhode Island and later enrolled at the prestigious Phillips Exeter Academy in New Hampshire. In 2009, he began studying at the University of Southern California (USC), though details about his college experience remain private.
Rise to Fame: Dewey on Malcolm in the Middle
Erik’s major breakthrough came in 2000 when he was cast as Dewey Wilkerson on Malcolm in the Middle, one of Fox’s most successful sitcoms. The series followed the chaotic and comedic life of a dysfunctional family, with Bryan Cranston and Jane Kaczmarek portraying Dewey’s overwhelmed parents. Dewey, the youngest of four (later five) boys, was initially portrayed as the quiet, innocent sibling—but over time, the character evolved to become more cunning and assertive.
Sullivan’s performance stood out. He delivered a perfect blend of humor, heart, and mischief that made Dewey a fan favorite. The role earned him multiple Teen Choice and Young Artist Award nominations and cemented his place in early 2000s television history. Malcolm in the Middle aired for seven seasons, wrapping in 2006, and remains a beloved cult classic today.
Film and Voice Acting Career
Even during his time on Malcolm in the Middle, Erik branched out into film and voice work. His career began with small appearances in notable films like Armageddon (1998) and The Cider House Rules (1999), but his first major film roles came in the early 2000s.
In 2001, he played the young version of David Spade’s character in the comedy Joe Dirt. That same year, he starred in the indie horror film Wendigo. In 2002, he appeared as the son of Diane Lane and Richard Gere in the erotic thriller Unfaithful, showcasing his ability to handle more serious and emotionally charged roles. He also made a memorable guest appearance on The King of Queens, playing a young Arthur Spooner.
In 2003, Sullivan lent his voice to Sheldon, the nervous seahorse in Pixar’s mega-hit Finding Nemo, and returned to voice work in 2007 for the fantasy film Arthur and the Invisibles, playing the role of Mino.
One of his final film roles came in 2004’s Christmas with the Kranks, where he starred alongside Dan Aykroyd, Tim Allen, and Jamie Lee Curtis. In 2010, he made his last on-screen appearance in Twelve, a teen crime drama directed by Joel Schumacher, co-starring Chace Crawford and Emma Roberts.
He also starred in the indie film Mo (2007), playing the lead role of a boy with Marfan Syndrome, further demonstrating his commitment to challenging and meaningful roles.
A Quiet Exit from Hollywood
After Twelve, Erik Per Sullivan quietly stepped away from the entertainment industry. Since 2010, he has maintained an exceptionally low profile. He is not active on social media, rarely gives interviews, and has not attended any Malcolm in the Middle reunions, much to the curiosity and concern of longtime fans.
Despite disappearing from the public eye, Sullivan’s body of work continues to speak for itself. His portrayal of Dewey remains iconic, and his brief filmography still resonates with fans today.
Erik Per Sullivan’s Net Worth and Lifestyle in 2025
Although he hasn’t acted in over a decade, Erik Per Sullivan’s net worth is currently estimated at $5 million. This figure reflects a combination of residual income from reruns, past salary from his television and film roles, and likely smart financial planning. Given the longevity of Malcolm in the Middle in syndication and streaming, residuals have likely played a significant part in maintaining his financial stability.
Unlike many former child stars, Erik appears to have intentionally stepped away from fame rather than being pushed out of the spotlight. There is no known scandal or public fallout. Instead, he seems to have chosen a life of privacy and perhaps normalcy—a rare feat for someone who grew up on screen.
