No One Knows Girls Like Agnes Irwin

Over 150 years ago, we were founded by Miss Agnes Irwin, the great-great granddaughter of Benjamin Franklin, first Dean of Radcliffe College, and advocate for the education of girls and young women — a radical concept in her time.

Today, Miss Irwin's legacy serves as our inspiration. In our Upper, Middle, and Lower independent girls schools, everything our students experience is rooted in what's best for girls: how they learn, how their brains develop, and what their social and emotional needs are. We know that when they feel known, understood, supported, and challenged, girls are empowered to be their very best selves.
