Round up your classmates, family members, and memories, and head to St. Louis September 17–19 to see your alma mater in action!

Sit in on Upper School classes, test out the climbing tower, and attend a varsity football game! We've got great entertainment lined up, along with opportunities to get off campus. Choose a guided tour of the Missouri Botanical Garden or Missouri History Museum, an architectural tour of the College campus, or a behind-the-scenes tour of Busch Stadium, home of the St. Louis Cardinals.

Of course, the best activity of all will be reconnecting with friends. Share your journey, learn where life has taken others, and find out how much you still have in common. 

The 2015 Upper School Reunion will be held September 17–19, and 50th reunioners arrive September 16. 

Join us for a weekend of fun!

Rekindle your connections with classmates. Check out what’s new on campus. Experience that hard-to-define difference that still makes Principia special after all these years.
