Nathan Fielder has built one of the most distinctive careers in comedy by turning his own awkwardness into art — the deadpan consultant of Nathan for You, the anxious architect of The Rehearsal. For years, fans assumed the lonely on-screen persona was basically the real guy. Then the internet discovered something the show had never mentioned: Nathan Fielder had been married. And divorced.
His ex-wife is Sarah Ziolkowska — not an actress, not a model, not a fellow comedian, but a librarian. A children’s librarian, to be precise, with degrees from the University of Toronto and Dalhousie University, who met Fielder at a comedy show in Halifax long before he was famous and married him in 2011, just as his career was beginning its climb.
But there is much more to the story than the marriage. Ziolkowska has built a serious, accomplished career in libraries and education — entirely on her own terms, entirely out of the spotlight — while Fielder has spent a decade processing the divorce in rare, strikingly honest interviews. In this article, we cover what is actually verifiable about Sarah Ziolkowska: her upbringing and education, her career as a librarian, how she met Nathan Fielder, what happened to the marriage, how the divorce affected him in his own words, what the internet gets wrong about the timeline, and the quiet professional life she leads today.

Who Is Sarah Ziolkowska?
Sarah Ziolkowska is a Canadian librarian who was married to comedian, writer, and director Nathan Fielder from 2011 until their divorce in the mid-2010s. She grew up in Toronto, trained as a librarian in Halifax, and has spent her entire professional life in libraries and education — a career she built before, during, and after her marriage to a famous comedian.
She is, by every available account, a private person who never sought any part of the entertainment world. She has given no interviews about the marriage, maintains no public profile, and is known to the public only through Fielder’s rare comments and the paper trail of her professional life. That paper trail, as it turns out, is more substantial than most celebrity-spouse biographies.
The honest caveat first: her date of birth, her family background, and the fine details of her personal life have never been made public. What is well documented is her education and her career — and the timeline of the marriage, which several gossip sites get wrong.
Early Life and Education
Ziolkowska grew up in Toronto, according to The Sun, which has published the most detailed reporting on her background. She studied Applied Science at the University of Toronto — a serious, technical undergraduate degree that suggests someone with a genuinely academic bent, not someone drifting toward the entertainment industry.
She then moved east to Halifax, Nova Scotia, to pursue a Master’s degree in Library and Information Science at Dalhousie University, completing it in 2009 according to reports. While at Dalhousie, she interned at the W.K. Kellogg Health Sciences Library and worked as a teaching assistant — the classic early steps of a librarian’s career.
Halifax matters for another reason: it is where she met Nathan Fielder. Fielder, a Vancouver native, was doing comedy in Halifax’s scene when the two crossed paths at a comedy show. They were together for years before marrying — one outlet reports they had been a couple for more than a decade by the time they split — which means their relationship predates essentially all of Fielder’s fame.
A Librarian’s Career — Before, During, and After Fame
What is genuinely impressive about Sarah Ziolkowska’s résumé is how continuous it is. Marrying a rising comedy star did not interrupt her career; divorcing one did not define it. She has simply kept working as a librarian for well over a decade.
After Dalhousie, she worked as a librarian and reading specialist at the Park Century School in California — a period that overlaps with the years she was married to Fielder and living in Los Angeles. Later, back in Canada, she reportedly served as head librarian at the Natural Sciences Library from 2022 to 2024, then took a role as a reference librarian at Fisheries and Oceans Canada, the federal department that manages the country’s fisheries and ocean resources.
Most recently, she has been reported as working as a youth librarian at the Halifax North Memorial Library — back in the city where she trained and where she met her ex-husband. There is something quietly symmetrical about that: a career that began in Halifax’s libraries continuing in Halifax’s libraries, the fame in between leaving no visible trace on the work itself.
How She Met Nathan Fielder
The most consistent account — repeated across multiple outlets — is that Ziolkowska met Fielder at a comedy show in Halifax before he became famous. This was the late 2000s: Fielder was a young Canadian comic working his way up through the scene, years away from Nathan for You.
The details beyond that have never been made public, and both parties have kept it that way. What can be said is that the relationship was long and, by all accounts, serious well before fame entered the picture. They married in 2011 in a private ceremony attended by close friends and family — the same year Fielder appeared on Jon Benjamin Has a Van and two years before Nathan for You premiered on Comedy Central.
That timing matters. Fielder’s on-screen persona — the awkward, romantically hopeless consultant — was being developed and broadcast while he was, in real life, a married man. Fans who later learned about the marriage were stunned precisely because the show gave no hint of it. Fielder told The A.V. Club that he deliberately kept his personal life out of the show, and that the television character was an exaggerated version of himself anyway.
The Marriage and the Split: Getting the Timeline Right
Here is where the internet needs correcting, because several biography sites mangle the dates. The reliable timeline, pieced together from Fielder’s own interviews and contemporary reporting, runs like this: married in 2011, separated in 2014, divorce finalized in 2015.
Some sites claim the couple married in 2014 — confusing the wedding with the separation — and at least one wedding-statistics site invents an entirely fictitious second marriage for Fielder. Neither is true. The marriage lasted roughly three to four years, ending just as Nathan for You was becoming a cultural phenomenon.
The reason for the split has never been disclosed by either party, and it should stay that way. What Fielder has said, repeatedly, is that the divorce devastated him. In a 2015 interview with The A.V. Club — his first real comments on the subject — he called it a “heavy emotional thing,” said it was the experience that had hurt him the most, and compared it to cancer, only worse. It is one of the rawest things the famously guarded comedian has ever said in public.
How the Divorce Shaped Nathan Fielder
Fielder has returned to the subject of the divorce obliquely but revealingly over the years, and his comments form the most human part of this story. In 2017, promoting the final season of Nathan for You, he told Rolling Stone: “Any breakup is hard. It was tough.” — terse, but from Fielder, practically a flood.
In 2022, speaking to Vulture about The Rehearsal, he went further, describing how the divorce had cracked him open years earlier: he recalled breaking down in the middle of an important meeting, thinking to himself, “I am so bad at life.” He spoke about his difficulty letting people in, about seeking therapy, and about how his then-partner — he was in a live-in relationship — had helped. “I have shared everything with her and it’s been fine,” he said, describing himself as genuinely happy.
There is a plausible reading of Fielder’s entire post-divorce career in those comments. The Rehearsal — a show about a man obsessively rehearsing human interactions he is terrified of getting wrong — premiered in 2022, seven years after the divorce was finalized. You do not need a psychology degree to see the through-line from a man who once broke down in a meeting thinking he was terrible at life to a show about rehearsing life itself.
What the Internet Gets Wrong About Sarah Ziolkowska
Because she has never spoken publicly, the gaps in Ziolkowska’s story get filled with errors. The main ones:
The wrong wedding year: several sites say Fielder married her in 2014. He married her in 2011; 2014 was the year they separated. It is a small error that scrambles the whole story.
The invented second marriage: at least one site claims Fielder married someone else in 2017. There is no credible evidence for this; as of the most reliable reporting, Ziolkowska is his only marriage.
The frozen-in-time career: many pages still describe her only as a “children’s librarian at Park Century School,” citing years-old LinkedIn data. Her career has continued in Canada since — through the Natural Sciences Library, Fisheries and Oceans Canada, and Halifax North Memorial Library.
The missing decade: most profiles treat her as a footnote to Fielder’s biography. In reality, she has a 15-plus-year professional career in libraries and education that stands entirely on its own — which is more than can be said for most “celebrity ex” profiles.
Life Today: A Librarian in Halifax
Today, Sarah Ziolkowska appears to be living exactly the life she trained for: working as a youth librarian in Halifax, Nova Scotia, far from Hollywood, out of the press, doing work she has done since 2009. She has no public social media presence, gives no interviews, and has never attempted to capitalize on her connection to one of comedy’s biggest names.
Fielder, for his part, has remained private about his personal life as well — he was reported in 2024 to be dating someone, but he has never remarried and rarely discusses relationships. The two appear to have gone their separate ways completely and quietly, which, given how the marriage ended, seems like the outcome both of them wanted.

Bottom Line
Sarah Ziolkowska never wanted to be part of the story of Nathan Fielder’s fame — and in the end, she isn’t. She was there before it, she left during it, and she has spent the decade since doing the work she trained for in the city where she trained for it. There is no scandal, no tell-all, no reinvention. Just a librarian who was briefly married to a comedian and went back to the library.
That might sound like an anticlimax, but it is actually the point. In a celebrity culture that treats every ex-spouse as content, Sarah Ziolkowska opted out completely — and built a life that needs no famous surname to justify itself. The books were always the point.
