Growing up in a “very working-class, almost poor” Jewish household in Queens, New York, David Krumholtz turned an open audition at age 13 into a career that would span Broadway, blockbuster films, and prestige television.
Born on May 15, 1978, the American actor is beloved for roles in The Santa Clause, Numb3rs, and Christopher Nolan’s Oppenheimer. In August 2026, he made headlines for a deeply personal reason that had nothing to do with a new role.
Who Is David Krumholtz?
David Krumholtz is an American actor with more than three decades of experience across film, television, and Broadway.
He is best known for playing Bernard, the head elf in The Santa Clause franchise, math genius Charlie Eppes in the CBS drama Numb3rs, and stoner buddy Goldstein in the Harold and Kumar film trilogy.
His most critically praised role came in 2023, when he portrayed Nobel Prize-winning physicist Isidor Isaac Rabi in Christopher Nolan’s Oscar-winning Oppenheimer.
Over the years, he has appeared in beloved comedies, prestige dramas, and major studio releases, building one of the most quietly impressive resumes in Hollywood.
In August 2026, Krumholtz shocked fans by announcing he was placing his acting career on hold. In a series of social media posts, he described himself as “frustrated, fed up, fried” with the entertainment business.
He later clarified he was not retiring outright, but needed time to care for his mental health and explore a deeper sense of purpose. The candid honesty resonated with fans and colleagues alike.
David Krumholtz Early Life
David Krumholtz was born on May 15, 1978, in Queens, New York City. His father, Michael, worked as a postal worker.
His mother, Judy, was a dental assistant who had emigrated from Hungary to the United States in 1956 during the Hungarian Revolution.
David’s paternal grandparents had come from Poland. The family was, as Krumholtz has said himself, “very working-class, almost poor.”
He grew up with an older sister named Dawn. Despite modest means, his parents supported his interest in performing from a young age. He attended P.S. 196 and later Stephen A. Halsey Junior High School in Forest Hills, Queens.
He went on to study at the Professional Children’s School in Manhattan before briefly attending New York University. He left NYU early to pursue acting professionally.
His path into show business started at 13 years old. He followed a friend to an open audition for the Broadway play Conversations with My Father and walked away with a role. That single decision changed the course of his life.

David Krumholtz Career
Broadway and the Early Years
Krumholtz made his Broadway debut in 1992 in the play Conversations with My Father, appearing alongside Judd Hirsch and Tony Shalhoub. He was just 13 years old. That debut opened doors in Hollywood almost immediately.
By 1993, he was appearing on film. He had small roles in Life with Mikey and Addams Family Values that year. In 1994, he landed what would become one of his most recognizable roles: Bernard, the head elf in The Santa Clause, starring Tim Allen.
That single role introduced him to a generation of young moviegoers and anchored him in the franchise for decades.
Rising Through the 1990s and 2000s
Through the late 1990s and early 2000s, Krumholtz became a familiar face in supporting roles. He appeared in The Ice Storm (1997), Slums of Beverly Hills (1998), and 10 Things I Hate About You (1999).
He joined Harold and Kumar Go to White Castle (2004), playing the lovable Goldstein, a role he reprised in two sequels. The Harold and Kumar trilogy gave him a cult following among comedy fans.
He voiced Mr. Universe in the sci-fi film Serenity (2005) and appeared in the acclaimed Ray (2004), playing a dramatic role alongside Jamie Foxx. His range was clear. He could do comedy and drama with equal ease.
In 2007, he had a memorable role in the hit comedy Superbad. Over the years, he added credits including The Mexican (2001), Bobby (2006), Walk Hard: The Dewey Cox Story (2007), and This Is the End (2013).
The Coen Brothers cast him in Hail, Caesar! (2016), and he voiced Lavash in Sausage Party (2016), a role he later reprised in the animated series Sausage Party: Foodtopia (2024).
Numb3rs: His Longest Television Run
Krumholtz’s biggest television role came on CBS’s Numb3rs, where he starred as mathematician Charlie Eppes from 2005 to 2010. The show ran for 119 episodes.
It was the rare instance of a character actor stepping into a true lead role on a major network drama. The role earned him a dedicated fanbase and remains what many viewers think of first when they hear his name.
Before and after Numb3rs, he had recurring roles on several other shows, including Monty, Chicago Sons, The Closer, and The Trouble with Normal. He later joined HBO’s acclaimed drama The Deuce, playing Harvey Wasserman from 2017 to 2019.
In 2020, he appeared as Monty Levin in HBO’s miniseries The Plot Against America.
Oppenheimer and a Career Peak
In 2023, Christopher Nolan cast Krumholtz as Isidor Isaac Rabi, the Nobel Prize-winning physicist, in Oppenheimer.
The film won Best Picture at the Academy Awards and was seen by millions worldwide. Krumholtz’s performance was praised by critics, and the role marked a new peak in his prestigious career.
Following Oppenheimer, he appeared in Apple TV+’s The Studio (2025), the Bruce Springsteen biopic Springsteen: Deliver Me From Nowhere (2025), and Sausage Party: Foodtopia (2024).
Most recently, he played Zor-El in DC Studios’ Supergirl, which premiered in June 2026. He also executive produced and starred in the independent comedy Forelock, which premiered at the Austin Film Festival in August 2025.
Broadway Return
Krumholtz returned to Broadway in 2022, playing Hermann Merz in Tom Stoppard’s Holocaust drama Leopoldstadt. The role earned him a Drama League Award nomination for Distinguished Performance.
It was a deeply personal project for Krumholtz, given his Jewish heritage and family’s connection to Eastern European history.
David Krumholtz Net Worth
David Krumholtz’s estimated net worth is $2 million as of 2026.
Real Estate
Krumholtz has made several real estate moves over the years. He paid $1.715 million for a Los Angeles home in April 2006 and sold it in August 2010 for $1.325 million.
That same November, he purchased a property in LA’s Larchmont Village neighborhood for $2.149 million, selling it in August 2012 for $1.5 million.
The family later relocated to New Jersey, purchasing a home in Teaneck in 2017 for $419,000. They sold that property in January 2026 for $599,000.
His most recent announcement, describing uncertainty about how he would earn a living after stepping away from acting, offers a candid window into the financial realities many character actors face, even after decades of steady work.
David Krumholtz Health: Thyroid Cancer Battle
In July 2011, not long after his wedding, Krumholtz discovered a lump on his neck. Doctors diagnosed him with thyroid cancer. He underwent a thyroidectomy and then received radioactive iodine treatment.
By January 2012, he was declared cancer-free. The experience was significant enough that he has spoken about it publicly on multiple occasions, including in a Reddit AMA session in 2014.
The battle left him with an ongoing need to manage his thyroid health, which he has connected to struggles with weight regulation.
David Krumholtz Wife and Family
His Marriage to Vanessa Britting
David Krumholtz married actress Vanessa Britting on May 22, 2010, at The Plaza Hotel in New York City. The couple reportedly began dating around 2005 and got engaged in 2008. Seth Rogen and Jay Baruchel served as groomsmen at their wedding.
Vanessa Britting is an actress and writer known for her roles in Without a Trace, The Unit, and Desperate Housewives. The two share a deep creative bond.
Britting has said her husband has been her biggest influence as an actor, noting that living with a working actor for most of his life provided her with an informal education in the craft. She has also worked as a realtor.
Britting has been a steady presence throughout Krumholtz’s career and his health challenges. They have maintained a low-key family life despite both working in entertainment.
Children
The couple has two children. Their daughter, Pemma Mae Krumholtz, was born in April 2014. Their son, Jonas Krumholtz, was born in December 2016.
When Jonas arrived, Krumholtz shared the news on social media with the caption: “His name is Jonas. My son. 8 lbs 15 oz.”
A year after Jonas was born, the family relocated from Los Angeles to New Jersey, where they have lived since.
David Krumholtz Career Break: August 2026
In August 2026, Krumholtz took to Threads to announce that he had placed his acting career on hold. His words were direct and emotionally raw. He described being “frustrated, fed up, fried” and said the profession had “lost its gleam.”
He wrote that he had spent the past year “fighting for parts” and felt the roles being offered to him would “exploit my talent and reputation for a drastically diminishing return.”
The posts were later deleted, but the response was immediate. Fellow actors and fans flooded him with support. Krumholtz followed up on Instagram to clarify that he was not retiring.
He wrote that his mental health was “vital” to his family and that he wanted to find a way to give more of himself to others rather than remain locked in the cycle of Hollywood self-promotion. He added that more work was coming, but asked fans to give him a moment to find his footing.
The announcement was striking for its honesty, coming just weeks after the premiere of Supergirl, one of the biggest films of his recent career.

Summary
David Krumholtz has spent more than three decades being the kind of actor that makes every film a little better the moment he shows up.
From a poor Jewish kid in Queens who talked his way into a Broadway production at 13, to a character actor in an Academy Award-winning blockbuster, his journey has never taken the expected path.
What makes him genuinely compelling is the same thing that drove him to step away, at least for now. He has always been honest, even when honesty is uncomfortable.
A husband, father, cancer survivor, and quietly essential piece of Hollywood’s fabric, Krumholtz is proof that the most lasting careers are built not on fame, but on showing up fully, every single time.
