Welcome to the Iowa Theta Chapter of Sigma Phi Epsilon at the University of Northern Iowa. The men of Sigma Phi Epsilon here at UNI are among 15,000 other brothers across the United States with more than 300,000 lifetime members making SigEp one of the largest Fraternities in the nation. SigEp is a non-pledging, non-hazing fraternity. Instead, the Balanced Man Program guides us through our four years at UNI, focusing on two key goals: Developing a Sound Mind and Building a Sound Body. If you have questions about our fraternity please direct those questions to the form at the bottom right of the page.
