Spring 2011 Pledge Class

Join a Brotherhood

Annual Tahoe and winnebago trips to football games at USC/UCLA are just some of the events to look forward to as a member. Brothers are always down to hang out, play sports, and crack down on academics when midterm season rolls around. We hold regular exchanges with sororities, and participate in numerous philanthropy events throughout the year.

Intramural Sports

Join Our Sports League

Sports we regularly participate in are soccer, basketball, and volleyball, among others. Many afternoons our half-court is bustling with basketball activity, or brothers head over to Underhill for pickup soccer or ultimate frisbee.


Succeed on Campus

For all Cal students, academics are a top priority, and members of DU are no different. We're proud to have a higher GPA than the all male average at Cal. DU brothers have a wide variety of majors, including Economics, EECS, Civil Engineering, Integrative Biology, Business Administration, and more!
