Why Reunion Gifts Matter

Reunion gifts are a way to honor the place that gave you a unique educational experience. By joining your classmates in giving a gift through the Caltech Fund, your support will make a difference in the lives of the students who follow in your footsteps. It's also an opportunity to celebrate a shared Caltech background and think about how you can help pay it forward to the next generation of Techers.

Mark the occasion of your reunion year by joining with other alumni and making a milestone gift through the Caltech Fund. Your contribution is considered a reunion gift if you give between October 1 and September 30 in the year of your reunion. In 2025, we are celebrating class years ending in 5 and 0.

If you're interested in learning more about Reunion Giving, including making a leadership-level annual gift or match to challenge and inspire your peers, or special giving opportunities such as endowed scholarships, planned gifts, or other complex transactions, please contact our annual giving team today.
