School Notes

  • On the edge of Concord, Massachusetts, just 20 miles outside Boston, beyond an entry column of overhanging maples, you`ll find the sprawling green campus of Middlesex, an independent secondary school for boarding and day students in grades 9-12. Keep heading to your right and you`ll see the main schoolhouse, where a small community from across the world gathers to pursue an education built upon a curriculum of outstanding breadth and depth. Peek inside a classroom to see an intimate group of passionate students as they discuss, analyze, listen, laugh, strive and thrive.The houses you`ll see on campus belong to our faculty, who open their doors day and night to talk with students about Hemingway, Newton, Caesar, the big game, that great concert, or nothing in particular. Academic expertise, commitment, and eternal energy, however, only partly define the faculty at Middlesex. Their passion for the careful development of complete, ethical teenagers is the true reason they`ve dedicated their lives to Middlesex.You`ll notice facilities that foster our cherished sense of community. Stop by our theater and maybe you`ll catch one of our full ensemble Broadway musicals. Head over to our non-denominational Chapel to hear a speech from one of our seniors, or maybe some Beethoven from our chamber music ensemble. Check out the Student Center and shoot some pool before the school packs in for an a cappella jam. If you want to enjoy some athletic competition elite or otherwise head out to our fields, where every student wears the Middlesex colors with pride.When you come to Middlesex, you`ll find a place full of opportunity, challenge, and friendship. A place to take risks and become a leader. A place to discover passions, talents, and yourself. A place, as our founder so aptly put it, to find your promise.
