Tradition | Brotherhood | Leadership

Steeped in history, the Sigma Triton Charge of Theta Delta Chi is one of the oldest continuous fraternities at Penn State.

Welcome to
Theta Delta Chi

The Sigma Triton charge of Theta Delta Chi is one of the oldest continuous fraternities at Penn State. Originally founded as Iota Chi Delta in 1915, our brotherhood has continued to grow as pillar of strength in the Penn State fraternal community.

Located at the corner of Prospect Avenue and Locust Lane, our house has stood for more than 90 years and has been the home for thousands of our brothers. We are one of the few Penn State fraternities that owns our fraternity house. That combined with our strong and active alumni base allows us to enjoy a remarkable level of stability.

Dedicated to building leaders, our alumni have gone on to run Fortune 500 companies, command our armed forces, and hold other significant positions of trust.
