Founder's Day Weekend

Celebrate the beginning of our legacy.

Did you know that Miss Agnes Irwin was just 27 years old when she was asked to lead an all-girls’ school in Philadelphia in 1869? Founder's Day Weekend serves as the kickoff to our Sesquicentennial Celebration, with Sunday marking 150 years, to the day, that our founder opened the doors to what would become The Agnes Irwin School. Join us as we mark this momentous occasion with a full weekend of activities from Friday, September 20 to Sunday, September 22.
