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.
Heartfelt, heritage-informed storytelling and creative services for small businesses.
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.
