We need YOUR Helping Hand.

“Scholarship opportunities like these take a lot of financial pressure off my back and allow me to put more of my time and energy into making our Fraternity the best in the world. I really appreciate your commitment to Theta Chi and your commitment to helping the younger generations succeed and grow as you once did. Thank you for extending the Helping Hand!”
