Resident Advisor

Luke Williams

I am proud to be the new RA for Mu Chapter. I’m looking forward to living with the men of Sigma Pi and learning more about them and their brotherhood.

I was born and raised in Omaha, Nebraska. I attended the University of Nebraska-Lincoln, where I pledged the Alpha Psi Chapter of Kappa Sigma. My junior year, I held positions in new member development and risk management. I graduated in 2019 with a BA in political science and minors in economics and national security studies. In August, I will begin my second year at Cornell Law School. This semester, I made the dean’s list and was elected to the executive board of Cornell’s American Constitution Society, Environmental Law Society, and Native American Law Students Association. This summer, I’ll be teaching criminal law to New York City high schoolers as part of the Legal Outreach Summer Law Institute. After graduating, I plan on practicing corporate litigation at a New York law firm.

My fraternity experience taught me valuable lessons that I hope to pass on to Sigma Pi. The ongoing changes in Cornell’s Greek life will present unique challenges that we must tackle together. Any members of the Mu Chapter community can feel free to reach me at

I am grateful for the opportunity to promote Sigma Pi values and advance man’s quest for excellence. Roll Pi!

Yours truly,
Luke Williams
