Saint Mark’s High School
#KCBlueLionPride
Saint Mark’s, a college-preparatory coeducational Catholic high school, inspires young men and women to create a better world, one more pleasing to God and more helpful to others, by modeling faith, excellence, humility, and integrity.

Construction on the School began in 1967, and the first students began attending classes in September 1969 under the leadership of Father Jim Delaney, the School’s first principal. Construction on the complex was completed in 1970, and the School was dedicated on 24 May 1970.
The School’s campus and facilities remained largely unchanged until 1995 when a formerly covered portico area was converted into office and lobby facilities as a part of the School’s Silver Anniversary Campaign. More recently, the School completed (in 2008) two additional athletic fields on lands that were gifted by the Catholic Diocese of Wilmington.
Saint Mark’s offers a rigorous college preparatory curriculum for students among the best and brightest of their peers locally, regionally, and nationally.
At the same time, Saint Mark’s provides a college preparatory experience for students of varying academic abilities as well. On average, 97% of all Saint Mark’s students move on to higher education, an achievement of which the people of Saint Mark’s are very proud.
In order to help students not only prepare for admission but for success in higher education, Saint Mark’s employs a holistic approach to the education of the young person – we strive to empower not only students’ minds, but their bodies, hearts, and souls as well.
