Bill Simon Field House 1 Year Anniversary

Lauren (Worley) Cornthwaite (US'95)

"The experiences I had and lessons I learned at Principia Upper School while playing sports have stayed with me—the love I garnered for field hockey at Principia moved me into the coaching profession and eventually gave me the tools and inspiration to turn my passion into a business that I run today."

Skyler Stock (US’22)

“In football, I’ve learned what it means to demonstrate grit. Whenever you’re tired, that’s the time it all really matters. Football is about who’s really willing to go hard, and even when you’re spent, you can still be a leader. This is the moment your true colors come out and when you either sink or swim.”
