Early Life and Education
Sarah Joy Ziolkowska was born in Toronto, Canada, with her birth date most commonly reported as May 12, 1983, though this detail has not been definitively confirmed in public records. She completed her high school education in Toronto before enrolling at the University of Toronto in 2002, where she earned a Bachelor of Applied Science degree in psychology in 2007.
Following her undergraduate studies, Ziolkowska pursued graduate education at Dalhousie University in Halifax, Nova Scotia, where she completed a master’s degree in library and information science in 2009. During her graduate program, she completed an internship at the W.K. Kellogg Health Sciences Library between 2008 and 2009, where her responsibilities included creating information literacy webcasts and assisting students and faculty with research resources.
This combination of an undergraduate degree in psychology and a graduate degree in library science gave Ziolkowska a strong foundation for the kind of specialized educational work she would go on to pursue, particularly her later focus on helping students with reading difficulties. Understanding both the psychological dimensions of learning and the practical skills of information science equipped her for a career centered on individualized academic support, well before her name became publicly associated with her future husband’s rising comedy career.
Meeting Nathan Fielder
Sarah Ziolkowska met Nathan Fielder in 2007, shortly after her graduation from the University of Toronto. According to accounts of their meeting, Fielder had traveled to Halifax to attend a friend’s comedy show when the two crossed paths and quickly connected. At the time, Fielder was still building his career in Canadian comedy, having previously won the Tim Sims Award in 2006 for outstanding Canadian comedy newcomer and joined the CBC comedy series This Hour Has 22 Minutes.
Their relationship developed over the following years as both continued building their respective careers, Ziolkowska in library science and education, and Fielder in comedy writing and performance.
Marriage to Nathan Fielder
Sarah Ziolkowska and Nathan Fielder married in 2011 in a private ceremony. At the time of their wedding, Fielder had not yet achieved the widespread recognition that would come with Nathan for You, the Comedy Central series he created that premiered in 2013 and became known for its unconventional, often cringe inducing business consulting premise. According to a Briefly profile of the couple, Ziolkowska enjoyed a relatively quiet life during the early years of their marriage, since her husband’s career had not yet taken off in the way it eventually would.
As Nathan for You gained a dedicated following and critical acclaim during its run from 2013 to 2017, Fielder’s public profile grew substantially, bringing increased attention to his personal life, including his marriage to Ziolkowska. This shift in visibility reportedly introduced new pressures into their relationship that had not been present during the earlier, more private years of their marriage.
Career as a Librarian and Reading Specialist
Throughout her marriage to Fielder, Sarah Ziolkowska continued working in her chosen field of library science and education. She worked as a librarian and teaching assistant, with her professional responsibilities including circulating collection and resource materials for staff and faculty, as well as helping students develop skills in digital literacy. At one point, she worked at Park Century School in Culver City, California, a school that specializes in serving students with learning differences.
Ziolkowska has also worked as a tutor through the Wilson Reading Program, a structured literacy program designed to help students with reading disabilities, including dyslexia. This specialized work reflects a career built around supporting students who face specific learning challenges, an area of education that requires focused training and a strong commitment to individualized instruction.

Reading specialists trained in structured literacy approaches like the Wilson Reading Program typically work one on one or in small groups with students, providing intensive, systematic instruction that differs significantly from general classroom teaching. Ziolkowska’s continued involvement in this kind of specialized tutoring, even amid the attention that came with her marriage to a rising comedy star, suggests a strong personal commitment to this particular area of education that has remained a constant throughout her adult life.
Divorce From Nathan Fielder
Sarah Ziolkowska and Nathan Fielder separated in 2014, with their divorce finalized the following year in 2015. Fielder has spoken about the divorce in general terms during interviews, describing the experience as emotionally significant even though the separation itself was largely amicable. In one interview, Fielder described the difficulty of discussing the divorce at first, noting that while it was not an extreme situation, it remained a heavy emotional experience for him to process.
Details about the specific reasons behind the couple’s separation have not been extensively publicized, consistent with both parties’ general preference for keeping personal matters private. Following the divorce, Fielder has generally kept his subsequent relationships out of the public eye as well, maintaining a similarly private approach to his personal life even as his career has continued to grow through projects including the HBO series The Rehearsal, which premiered in 2022.
Life Since the Divorce
Since her divorce from Nathan Fielder, Sarah Ziolkowska has continued her career in library science and reading education, maintaining a private life largely disconnected from the entertainment industry that brought her former husband significant fame. She does not maintain a verified public social media presence, and unverified accounts using her name should not be assumed to be authentic, given her consistent preference for privacy throughout and after her marriage.
Little additional information about her life since 2015 has been publicly documented, a reflection of her deliberate choice to step away from any public attention connected to her past marriage. This approach has remained consistent even as Fielder’s profile has continued to rise through his subsequent television work, which Time magazine recognized in 2023 by naming him one of the 100 most influential people in the world.
Why People Are Curious About Sarah Ziolkowska
Interest in Sarah Ziolkowska largely stems from her marriage to Nathan Fielder, whose distinctive comedic style and unconventional television projects have made him one of the more talked about figures in modern comedy. Because Ziolkowska has maintained such a consistently private profile both during and after their marriage, fans curious about Fielder’s personal life have found her story notable primarily for her professional dedication to library science and reading education, a career path entirely separate from the entertainment world her former husband inhabits.
Conclusion
Sarah Ziolkowska’s career as a librarian and reading specialist reflects a life built around education and quiet, individualized support for students, one that has remained steady and private both during and after her marriage to comedian Nathan Fielder. Her consistent preference for privacy, even as her former husband’s fame has grown, shows a deliberate choice to keep her professional life separate from the entertainment industry.
