As a chapter we participate in Western's Homecoming week each year. We team up with other Greek organizations and participate in events such as Variety Show, Yell like Hell, Bubble Soccer, and the Homecoming parade. Sigmas also participate in WIU's Greek Week every year which has events such as a banner contest, Pasta Cookoff, Jeopardy, FSL's Got Talent, Big Pink Volleyball, etc.
Within Greek Life our women are involved in many organizations such as Rho Lambda, Order of Omega, Greek Review Board and the Panhellenic Executive Board. We also encourage our members to be active in other organizations around Western's campus such as Best Buddies, University Union Board, WIU Cheerleading, the Western Courier, Student Government, the First Year Experience Program, Scuba Club, Rockython, Centennial Honors College, WIU Westernettes, Intramural sports, and clubs that are designed for their majors.
