O'Dea High School

O'Dea High School is a Catholic school in Seattle located in a building behind St. James Cathedral, serving students in grades 9 through 12. The campus includes modern classrooms, athletic facilities, and offers a range of academic programs for its student body.

The Archdiocese of Seattle founded the school in 1923 and named it after Edward John O'Dea, who was serving as bishop at that time. Since its establishment, the institution has remained a Catholic educational presence in the Seattle area.

The institution follows the motto 'Omnia Omnibus' and maintains a student body representing multiple ethnic backgrounds through active cultural clubs and organizations.

The school is located in the First Hill area of Seattle and is accessible by public transportation. Visitors should know that the campus operates during the school week with limited public access to the grounds.

The school operated for decades as the only all-boys high school in the Pacific Northwest region. This distinctive role set it apart from other educational institutions in the surrounding area.
