School Notes

  • Founded in 1865, St. Mark's School educates young people for lives of leadership and service, challenging students to take charge of their education, inspiring their academic and spiritual curiosity, and kindling their passion for discovery.
  • We have crafted an intentionally small community with the specific goal of encouraging close relationships between faculty and students that gives our students courage to stretch, to dream big, and think beyond themselves.Innovation and tradition are part of our educational DNA.

Graduates leave St. Mark`s ready to live lives of consequence in the 21st century.
