A nationwide tradition of Leadership, Service, and Brotherhood.


The Mu Chapter of Theta Chi Fraternity, founded in 1913, took its place as a historic landmark by becoming the first chapter West of the Mississippi River. For over 100 years, Theta Chi has been a foundation of support for college students at the University of California - Berkeley. Inspiring its members to become leaders, creators, and most importantly brothers, we thrive on the ideals of the national fraternity to produce well educated and respectable gentlemen.



Behind the success and accomplishments of the Mu Chapter is its outstanding brotherhood. With brothers from across the United States and other countries of the world, we are proud of the diverse group of men and broad spectrum of interests and skills that constitute our chapter.
