Welcome to the Western Reserve Chapter of the Delta Upsilon International Fraternity! Delta Upsilon (DU) is a non-secret international men's fraternity founded in 1834. We are committed to Building Better Men through our four Founding Principles: Promotion of Friendship, Development of Character, Advancement of Justice, and Diffusion of Liberal Culture. The core principles of the fraternity challenge our brothers to expect nothing less than excellence from themselves and others.
