Who We Are

Since our inception on February 26, 1897, at Vincennes University in Indiana, Sigma Pi has grown into an international Fraternity which prides itself on brotherhood, scholarship, chivalry, and leadership. Our men strive for excellence by living our core values to promote fellowship, develop character, advance heightened moral awareness, enable academic achievement, and inspire service.


The #whyibelieve campaign revolves around the idea of “if Sigma Pi didn’t exist, where would I be?” This campaign captures the positive influence being in a fraternity has had on your life and is centered around the idea that there is more to the fraternity experience than meets the eye. Being in Sigma Pi creates opportunities that may not have been presented otherwise and we want to showcase this throughout the campaign. We encourage you to share why you believe in Sigma Pi on social media using the hashtag #whyibelieve
