Alpha Sigma Phi, Pi Chapter, represents the best of Greek life at CU Boulder. We are a community of gentlemen who dedicate ourselves to bettering our community by bettering ourselves.

We pride ourselves on our philanthropic efforts. In 2015 we  teamed up with the rap group Zion I to benefit RAINN and held our 3rd annual "Alpha Sigma Phry" benefitting Homes for Our Troops. Overall, we raised over $11,000 for some great causes over the last year.



Alpha Sigs know that academics comes first. We have an in-house tutoring system which pairs brothers together based on their majors and expertise. In 2015 Alpha Sig improved more academically than any other chapter in Boulder, surpassing the all men's average at CU.

Community Service

Our brotherhood would not be the same without our incredible community. Alpha Sig has teamed up with Boulder Open Space, Community Food Share, and iTHRIVE to make an impact on our local area as well as organizing hill cleans to keep the Hill looking great.
