Delta Nu Psi has been Keene State College's only co-ed fraternity since being founded over 20 years ago by three great friends. An influential brotherhood of men and women dedicated to friendship, equality, and improving the community, we have greatly affected Greek Life on KSC's campus. After two decades of memories and achievements, Delta Nu Psi has proudly opened a new chapter to our history by becoming apart of the national fraternity Psi Upsilon.

Psi Upsilon is the fifth oldest fraternity in the United States and is filled with a rich history and strong value based way of life. Psi Upsilon was founded in 1833 at Union College and over the years spread through out the nation. There are over 40 chapters, the Delta Nu chapter of Keene State College being the newest.
Psi Upsilon has many historical alumni including 2 presidents, the first FBI director, the Prime Minster of Canada, director Michael Bay, author of the "DaVinci Code" Dan Brown, and the founders of Coors Brewery Jeffery and Peter Coors. The former brothers and sisters of Delta Nu Psi are extremely proud to become apart of such a respectable and well known family that have the same morals, beliefs, and values that we have had for over 20 years.

Psi Upsilon's motto: "unto us hath befallen a mighty friendship" couldn't explain the mergence of the former Delta Nu Psi and Psi Upsilon any better.
