Founded in 1901, and located in one of this country's most historic towns, Concord, Massachusetts, Middlesex aspires to help its students "find their promise" through immersion in a rigorous academic program, inclusive extracurricular programs in arts and athletics, and a commitment to service. Middlesex students are exposed to a breadth and depth of opportunities typically found at only a much larger school.
Over 145 classes include five languages, a much emulated Writing Program, and over 40 advanced and AP sections that wil stretch students intellectually as they pursue academic passions.
At Middlesex, everyone engages in cocurricular life, participating in a thriving arts program (including a third of the school performing via vocal, instrumental or dramatic groups) that ofters opportunities for the beginner to high-end artist; similarly, each student participates in athletics, and we have a home for both the elite athlete and those new to team sports.
All of this work takes place in a community strengthened by our shared commitment to five core values: honesty, respect, kindness, gratitude, and courage.

School Notes:

  • Middlesex School Mission and History
    Frederick Winsor wanted the school he founded in 1901 to be distinct from the boarding schools of the time, and from its beginnings, Middlesex School has occupied a unique place in the independent school landscape. It is a non-sectarian School with a positive sense of tradition and mission. It is a school with small-school intimacy and big-school opportunity, a school that early on sought students from every part of the country through a National Scholarship Program. As it has grown, Middlesex has broadened its national and international reach while always benefiting from its local surroundings—the human and cultural capital of the Boston/Cambridge area. Middlesex School, both in the present and in the past, has preferred capacity in many areas to specialization in one. We believe a transparent and familiar community is an ethical community. We believe in our students. From the start, Winsor’s mission was to “find the promise that lies hidden” in every student, and that message of individuality, hope, and possibility guides us today. Our campus, designed by the Olmsted Brothers firm, remains centered on its iconic circle. We are fortunate to live in a beautiful setting that naturally brings our paths and our lives together. Radiating from a common sense of place and purpose, Middlesex continues to prepare its students for a changing world. We have evolved in many ways since our founding over a century ago. We have undergone renovation, conservation, expansion, and constant transition in person and place. Yet our buildings, our fields, our programs, and our ethos still cleave to a human scale fostering collegiality and contact. Despite the school’s continuous transformation, our mission, with our students at the center, remains the same.
