The Knox School

  • Imagine living and learning in an inclusive community in which people thrive in an environment where taking risks is revered and achieving more than one ever imagined is a reality.
  • Imagine athletes performing in musicals and choir, and artists being competitive fencers.
  • Imagine students affectionately calling their school campus their "home beside the shore" where they have experiences that impact their lives in ways they never dreamed possible.
  • Imagine students graduating high school with the self-confidence to try new things, the work ethic to thrive in a college or university and with a true belief in the power of their own efforts.

The school has established a climate that promotes excellence and leadership among students in a caring and supportive environment. My daughter participated in crew which was a great experience that opened her up to challenges as well as provided unique opportunities.
