Theta Chi - Delta Eta

Theta Chi - Delta Eta For more info, visit us at thetachicsu.org. The Official page for Theta Chi Fraternity at the Colorado State University (CSU).

Theta Chi Society, as it was originally known, was founded at Norwich University in Norwich, Vermont, at nine o'clock on Thursday evening, April 10, 1856. On April 27th of 2013, Theta Chi Fraternity arrived at Fort Collins to rejoin Colorado State University as the Delta Eta Chapter after 40 years off the the campus. The Delta Eta chapter of Theta Chi was founded by an Alpha class looking to create a different kind of Greek experience; an experience that would create the best men on campus. So far Delta Eta has done this with academic excellence, extensive campus involvement, and numerous awards. If you are a male student of CSU looking to be a part of something bigger than yourself, with some of the most prestigious men on campus, then Theta Chi is for you.

THROWBACK THURSDAY!!
Since 2013, we have had a multitude of different faces come and go here add to the Delta Eta chapter at Colorado State University.

Many of the brothers in these photos helped to build the chapter that we are able to enjoy to this day.

A big thanks to some of our most recent Alumni, as they have truly strengthened our chapter further. Here's to many more years to come!

Statement from the Delta Eta Chapter of Theta Chi at Colorado State.

As members of Theta Chi, we remain actively committed to respect, safety, and accountability. We firmly condemn the actions and conduct that occurred at Cornell and believe that further action must be taken at an organizational and institutional level.

Our hearts go out to those affected by this event and all those affected by any sexual violence & misconduct.
