Sigma Phi Society - Alpha of Wisconsin

We are the Sigma Phi Society. Founded in 1827, we are the longest continually active social fraternity in the United States. Sigma Phi believes in developing students into leaders through participation in a collaborative, engaging, and inclusive setting where member’s voices can be heard and make a difference. We strive to cultivate lifelong friendships amongst our members that cross through artificial barriers by fostering a tight-knit community of brothers. The goal of Sigma Phi is to translate the skills members develop into being better students, family members, and leaders at the University of Wisconsin-Madison and for the rest of member’s lives.

We have been an active fraternity at the University of Wisconsin since 1908. We live at 106 N Prospect Avenue, just west of Camp Randall, in the Harold C. Bradley house, designed in 1908 by renowned architect Louis H. Sullivan.  It is Madison's first national landmark and we have been proudly taking great care of it since 1915.
