Class of 1976

Welcome Home Class of 1976

Can you believe it’s been almost 50 years since we graduated? The 2026-2027 school year is right around the corner and we are gearing up for our 50 Year Golden Celebration—and we want YOU to be part of making it unforgettable.

We’re looking for classmates to help plan, a reunion full of laughs, memories, and maybe a few surprises. Whether you’re an organizer at heart or just have great ideas, there’s a place for you on the committee.

Let’s make this 50th reunion something we’ll all be talking about at the 60th!

If you wish to help plan your 50th reunion or update your contact information, please e-mail Danielle Hill '01 Mater Dei's Manager of Annual Fund & Alumni Relations.
