Who Is Sarah Ziolkowska? The Real Story of Nathan Fielder’s Ex-Wife

Sarah Ziolkowska is a Canadian librarian and reading specialist who became known to a wider public through her former marriage to comedian Nathan Fielder. Fielder is the creator and star of Nathan for You and The Rehearsal, two of the most talked about comedy programs of the past decade. As his fame grew, curiosity about his private life grew with it, and the name sarah ziolkowska began appearing in search results around the world.

The real story is quieter and, in its own way, more interesting. Ziolkowska is an information professional whose career is about libraries, literacy, and helping students find and use reliable information. She has never given interviews about her marriage and has kept her life private since the divorce. This article follows the documented record, and it is honest about the places where published sources disagree with each other.

Quick Facts

Background and Education

Sarah Ziolkowska grew up in Toronto, Canada. Several published profiles report that she was born on May 12, 1983, although that date comes from secondary biography sites rather than from any statement by Ziolkowska herself, so it is best treated as reported rather than confirmed. What is well documented is her education, because universities keep public records of their graduates.

She studied at the University of Toronto, where profiles say she completed an undergraduate degree with a focus on psychology in 2007. She then moved to Halifax, Nova Scotia, for graduate school at Dalhousie University. Dalhousie’s School of Information Management lists her as a 2009 graduate of its library and information studies program, and the university later noted her appointment as a school librarian in Los Angeles. That graduate record is the strongest anchor in her biography.

The direction of her studies tells its own story. A background in psychology, followed by professional training in how people find, judge, and use information, is a fitting path for someone who would spend her career helping children and students read better and research better.

Her Career in Libraries

Ziolkowska began her professional work while she was still completing her master’s degree. In 2009 she was a library intern at the W.K. Kellogg Health Sciences Library at Dalhousie. The work included creating information literacy webcasts and helping students with research projects and reference questions. She also worked as a teaching assistant at Dalhousie after graduating.

Her best documented role came in California. From October 2012, she worked as a librarian and reading specialist at Park Century School in Culver City, a school that serves students with learning differences. In that role she managed the library collection and reference resources for students and staff, and she supported reading development, including work with digital literacy ideas. Profiles also report that she earned Wilson Reading System certification in 2015, a specialist qualification in structured reading support.

Other profiles connect her with library work back in Canada, including youth librarian work at Halifax North Memorial Public Library and roles linked to specialist and government libraries. The exact order and dates of those later roles are reported differently by different sites, and she has no public profile of her own to settle the question. The clear thread through every account is the same: her working life has stayed inside libraries and reading education, on both sides of the border.

Her work also had a digital side that fits the times. School librarians today do far more than shelve books. They teach students how to search well, how to judge whether a source can be trusted, and how to stay safe and thoughtful online. The webcasts she helped create as an intern were an early form of exactly that teaching, short lessons that students could use whenever they needed them. Colleagues in the field describe this mix of reading support and information skills as the heart of the modern school library, and it is the mix her whole career has been built on, from a health sciences library in Halifax to a school library in California.

Marriage to Nathan Fielder

Not much is reliably known about how Sarah Ziolkowska met Nathan Fielder. The most common published account says the pair met before Fielder became famous, at a time when he was building his comedy career in Canada. Fielder, born in Vancouver in 1983, worked in Canadian television before creating Nathan for You for Comedy Central in 2013.

Even the basic dates of the marriage are reported differently, and honesty requires saying so. Some profiles say the couple married in 2011, in a private ceremony. Others give earlier or later years. The divorce is likewise dated to 2014 by some sources and 2015 by others. What every account agrees on is the shape of the story: they married before or just as his American television career took off, the marriage lasted a few years, and it ended in the middle of the run of Nathan for You.

Fielder himself has said very little. In a 2017 interview with Rolling Stone, he made a rare, short comment about the divorce. Any breakup is hard, he said. It was tough. He also confirmed he was dating someone new at the time, and refused to say more. Ziolkowska has said nothing publicly at all, then or since.

Life After the Divorce

Since the marriage ended, Sarah Ziolkowska has lived entirely outside the entertainment spotlight. She has no known public social media presence, gives no interviews, and has never written or spoken about her former husband for the press. While Fielder went on to create The Curse with Benny Safdie and Emma Stone, and to return with a second season of The Rehearsal, her name appears in the news only when audiences grow curious about his past.

It is also worth noting what she did not do. She did not sell a story, sign a book deal, appear on a reality program, or build a social media following from a famous surname that was never hers to begin with. In interviews over the years, Fielder himself has kept the same respectful silence about the details of the marriage, which suggests the privacy was a shared value and not a public relations move. Two people who once shared a life simply agreed, in practice, to let it stay in the past.

Her professional life, by all published accounts, continued on the same path of school libraries, reading support, and youth library work. There is something worth respecting in that consistency. Many people connected to a rising celebrity change course and chase the attention. She did the opposite, returning fully to the career she had trained for before the marriage.

Because she is a private person, this article avoids the invented details that fill many pages about her, such as unsourced wealth figures or claims about her current home and relationships. No reliable source publishes a net worth for her, and her present personal life is simply not public information. The documented record, a strong education and a steady career in literacy, is a complete enough story on its own.

She trained at two Canadian universities, built a career helping students read and research, and continued that work after a short marriage to a comedian who became very famous.
