"Teachers made this school. Teachers with a love of children in their hearts; teachers who are eager searchers of truth; teachers who are willing to share their longer experience with children and at the same time are able to learn from the naturalness and sincerity of their pupils.”
—Margaret Chadwick, 1952
Throughout our 80-year history, one of Chadwick School's most marked attributes has been, and continues to be, the exceptional quality of our faculty and staff. Of our 109 faculty members in grades K-12, 80 percent have advanced degrees, and many have worked professionally in the specialized fields in which they teach. Furthermore, with a student-to-faculty ratio of 8:1, our faculty have the freedom to teach to their fullest capacity - inspiring students every step of their journey.
