About
Today is Founders’ Day - a chance for our community to come together and make a difference for GSB!
Parents, past parents, alumni, faculty and staff, and friends are joining forces to celebrate our school and invest in the future of every student. When our community shows up together, the impact is powerful.
At GSB, we are all Founders. Each of us plays a role in sustaining and uplifting the spirit, opportunity, and excellence that define our school. Your participation today helps ensure that current and future students can be seen and know while discovering their strengths, pursuing their passions, and finding their personal greatness.
Gifts made today support the GSB Fund, a vital part of the School’s annual budget that bridges the gap between tuition and the true cost of educating a child. The Fund supports the people and programs that make GSB exceptional, from inspiring faculty and professional development to student activities, athletics, performing arts, campus spaces, and classroom resources.
Every gift matters. Every donor counts. Join your fellow community members and help make Founders’ Day a success.
Make your gift now and be part of the momentum.
