Welcome to Sigma Pi Fraternity at Oregon State University. We are a fraternity of gentlemen and the ideals of Sigma Pi are shaping each of us into the next generation of leaders. Sigma Pi men come from a wide variety of backgrounds and cultures and are bonded together by the brotherhood that is Sigma Pi Fraternity.

About Us

The gentlemen of Sigma Pi are men of high character who share common values embraced by the chapter. Among our common values are Truth and Justice, Scholarship, Diversity, Chivalry, and Character.

Our values and character are exhibited in everything that we do. We believe in developing well rounded men to be the next generation of leaders. Intramural sports, social events, formal events, campus groups and clubs, scholarship commitments, and brotherhood events are just a few examples of the involvement of Sigma Pi brothers.
