Friends,
Thank you for being part of this extraordinary moment for Agnes Irwin.
Our school is thriving. We are seeing record enrollment, a vibrant and engaged community, and rising interest in the singular experience of an Agnes Irwin education.
At Agnes Irwin, we never rest on our laurels. We are always thinking about what our girls need to thrive today and to lead tomorrow—with confidence, curiosity, commitment, and joy.
This forward-thinking mindset is at the heart of ALL IN, a visionary campaign that calls on all of us to come together to invest in our girls and their futures.
Our most urgent priority is revitalizing our campus to reflect how girls learn best, featuring a reimagining of our Middle and Upper School Building. I invite you to learn more about how a building designed specifically for girls will expand opportunities for all of our students.
Beyond our building plans, we are also growing Agnes Irwin’s endowment through lifetime and planned gifts. Strong endowments make for secure legacies.
Meeting this moment means all of us must come together in support of the future of this extraordinary institution. By investing in our campus and endowment, we are ensuring the legacy of Agnes Irwin and the futures of generations of Owls.
I am so grateful you choose to stand with us—and always for our girls.
Warmly,
Sally B. Keidel, Head of School
Campaign Progress
as of October 21, 2026
“We are heartened to see such impressive momentum behind this campaign. And we're just getting started. ALL IN is the opportunity for everyone to help lay the groundwork for what our school will look like in the next 10, 20, and even 50 years.”
ANNE & DAVID FORD P’30, CAMPAIGN CO-CHAIRS
PRIORITY 1Revitalize Our Campus
$30 million to renew our MS/US building
Agnes Irwin’s mission calls on us to prepare girls for a future we can’t yet imagine. Doing so means rethinking the spaces and facilities where girls learn, collaborate, thrive, and compete.
Our Middle and Upper School Building has been the heart of the student experience since 1961. With its infrastructure stretched to the limits, we face an urgent task: reinvent our founding academic building to meet girls’ needs smartly and sustainably.
We are boldly reimagining the Middle and Upper School building with vibrant, flexible environments designed to foster inquiry, innovation, and connection. Renewed, reorganized spaces—infused with light, equipped for project-based learning, and engineered to emphasize sustainability—will mirror the education unfolding inside.
This generational moment offers you the opportunity to fulfill the promises we make to each girl who walks our halls. Ensuring our campus continues to be as distinctive and extraordinary as the educators and girls who call it home.
OUR VISION FOR WHAT'S NEXTInside and out, we are reimagining our core academic building as an optimal environment for teaching, learning, and collaborating—geared expressly to how girls learn best and how we must all continue to innovate and grow.
TRANSFORMING OUR MS/US BUILDING
CREATING INSPIRING SPACES INSIDE
“A great education calls for great spaces. As parents, we believe in creating teaching and learning environments that anticipate and elevate our daughters’ aspirations.”

PRIORITY 2Supercharge Futures
$20 million to grow our endowment
When you give to Agnes Irwin’s endowment, you’re signaling your trust in our school and our leadership, while expanding the possibilities ahead.
This campaign will significantly grow Agnes Irwin’s endowment, taking it to a level that reflects the caliber of our education, our national leadership of girls’ education, our positioning in the marketplace, and our momentum.
A more robust endowment represents our margin of excellence. It generates a predictable stream of income, directed at new and emerging priorities. It allows us to say yes to more deserving students, regardless of financial means. It recruits and retains the best faculty.
Your support creates a lasting legacy—through lifetime gifts, planned giving, and outright gifts. By signaling you are ALL IN for Agnes Irwin, you increase our impact with time, fuel future aspirations, and ensure we remain a powerful force for good.
“All of us are focused on supporting future generations of Irwin’s girls who will benefit from this extraordinary 21st-century education.”
JIM BUCK P’13 ’15 ’17, CAMPAIGN HONORARY CO-CHAIR
PRIORITY 3Invest in All Our Girls
$15 million to advance an education designed for girls
At Agnes Irwin, each girl’s experiences are unique. We are ALL IN on meeting her where she is, with an education that reflects best practices and leading-edge research, gathered by our Center for the Advancement of Girls.
Even as we address emerging needs, endowment growth, and the renewal of our core building, we must keep advancing day-to-day excellence: curricula and co-curricular experiences, arts and athletics, distinctive and innovative programs, like leadership development for all divisions. These elements, designed expressly for girls, anchor the depth and quality of an Agnes Irwin education.
Campaign philanthropy, especially gifts made through EITC and to the Annual Fund, will grow and expand these ingredients for success, all led by outstanding educators who understand how girls learn and are intent on preparing them for demanding careers and fulfilling lives.
When you invest in the best girls’ education, you enable our girls to shape the world.
“The greatest gift my parents ever gave me is my Agnes Irwin education. It’s our responsibility to pay this gift forward.”
