Our School is the Twin Ports flagship independent school and has served the Duluth area for more than a century. Founded in 1904 as Cathedral Senior High School, Marshall has adapted with Duluth as the educational needs of the community changed. The foundation of providing the highest-quality, college-preparatory educational experience to students in the area has always remained a part of the school's history.

Along with always being known as the Hilltoppers, Marshall's unique history has consistently upheld the values of exhibiting strong academic habits, integrity, respect, and compassion.
