Who We Work With

We work with amazing small businesses and academics — from the Washington DC-Baltimore area to the Midwest.

"We loved working with Saseo Studio! Katie's warm and professional demeanor put our entire team at-ease as she captured beautiful photos of our shop and personnel.

Her attention to detail and commitment to authenticity really helped capture our shop's essence, and her photos have become a central part of our brand's storytelling. Highly recommend!!"

Who We Are

Katherine (Hyun-Joo) Mooney, PhD, is a historian with over a decade of professional experience in research, writing, and public storytelling. Before founding Saseo.Studio, she created and managed content for a major government website that received over 90 million views in 2025.

Her work spans peer-reviewed scholarship and public-facing writing. See her article on Zambian rock music in the 1970s in The Journal of Popular Music Studies (March 2026) here. Her writing has appeared in Truthdig, Picturing Black History, Army History, Africa Is a Country, and in many other publications. She previously worked at the U.S. Army Center of Military History, contributing to the research and publication of official history volumes.

Katherine brings hands-on production skills to Saseo.Studio, including professional photography, archival digitization, oral interviews, content production, social media content creation and design work. She founded Saseo.Studio to help small businesses document their work, share their stories, and build meaningful connections within their communities.

Our Work

The Saseo.Studio logo is inspired by traditional Korean seal stamps (도장), which were used to sign documents, mark authorship and authenticate records.

The word saseo (사서) refers both to a historical record keeper or archivist and to the Four Books, a foundational collection of classical texts that shaped scholarship and moral thought in East Asia.

Together, the seal stamp and the word 사서 reflect Saseo.Studio’s commitment to careful documentation, intellectual tradition and long-term stewardship of stories and archives.
