Sarah Ziolkowska is a Canadian library and information professional whose public profile has often been shaped by her former marriage to comedian Nathan Fielder. Beyond that connection, the available record shows a career built around librarianship, youth services, community programming, and research support.
Ziolkowska has worked in several library roles, including positions with Halifax Public Libraries and the Nova Scotia Natural Sciences Library. As of 2026, professional records list her as a Reference Librarian with Fisheries and Oceans Canada in Dartmouth, Nova Scotia. Her career reflects a focus on connecting people with information, from children’s programming to specialized research collections.
Education and early library work
Ziolkowska studied at the University of Toronto before earning a Master of Library and Information Science (MLIS) from Dalhousie University in 2009. Her professional path developed around public access to information and library programming rather than public entertainment or media work.
Early in her library career, she contributed to Dalhousie University’s YA Hotline, a publication focused on youth library services. The archive credits her with articles exploring creative programming approaches, including craft activities designed to engage young library users.
Her early work demonstrated an interest in using libraries as active community spaces rather than simply places for book collections. That focus continued throughout her later public-library career.
Building a career in youth librarianship and community programming
Before joining Halifax Public Libraries, Ziolkowska worked as a school librarian in the United States. By the late 2010s, she was serving as Youth Librarian at Halifax North Memorial Public Library.
During that period, she became associated with the FoodSmart Project, a library initiative focused on community engagement through food-related programming. She also presented on how food programs could help libraries create stronger connections with their communities.
Her work in Halifax reflected a broader approach to modern librarianship: using library spaces for education, social connection, and practical community support.
Leadership at the Nova Scotia Natural Sciences Library
By 2024, Ziolkowska had moved into a leadership role as Head Librarian at the Nova Scotia Natural Sciences Library. The institution supports research and information needs in areas including geoscience, forestry, wildlife, mining, and Crown land resources.
In that role, she also contributed to public-facing knowledge work. At the 2024 Nova Scotia Genealogy Virtual Conference, she presented information about research resources such as Crown land grants, maps, and historical index materials.
The move from youth services into a specialized research library position marked a progression from community programming toward managing access to technical and historical information resources.
Her connection to Nathan Fielder
Much of the public curiosity surrounding Sarah Ziolkowska comes from her former marriage to comedian and television creator Nathan Fielder.
Fielder has discussed the relationship in interviews without naming Ziolkowska directly. He said he met the woman he married at a friend’s comedy show in Halifax and that they married in 2011. He later described the marriage ending about three years afterward, during the period when he was working on the second season of Nathan for You.
In a 2015 interview with The A.V. Club, Fielder described the divorce as amicable but emotionally difficult. His comments provide insight into his own experience, but Ziolkowska has not publicly provided her own account of the separation in the sources available.
The specific reason for the divorce has not been publicly established by reliable sources.
What is known about Sarah Ziolkowska today
The most recent professional record available lists Ziolkowska as a Reference Librarian with Fisheries and Oceans Canada in Dartmouth, Nova Scotia. This continues the same information-services career path seen throughout her earlier roles.
Although online profiles often focus on her connection to a well-known comedian, the documented record presents a different picture: a librarian whose career has included youth services, community programming, specialized research collections, and government information support.
Details such as her exact birth date, age, net worth, private relationships after her marriage to Fielder, and other personal information have not been reliably confirmed through authoritative sources and are not necessary to understand her public work.
Final thoughts
Sarah Ziolkowska’s public significance comes less from celebrity association and more from a sustained professional career in librarianship. From youth programming in Halifax to specialized research services in Nova Scotia and federal government work, her documented career shows the evolving role of librarians as educators, researchers, and community information specialists.
