June 4–6* | HMS and HSDM Classes Ending in 1 and 6
No matter how long it’s been since you were last with your classmates, you can renew old friendships—and forge new ones—while rediscovering the School during your Reunion in 2026. We hope you will join us to celebrate.
* The core Reunion program will be held June 4–6 (20th–55th classes) and June 5–6 (5th–15th and 60th classes).
