The third sorority on campus, Sigma Zeta Chi was, like Chi Delta Chi and Delta Epsilon Nu, founded with the goal of producing well-educated, well-mannered young ladies fully prepared for future lives as wives and mothers. Unlike the other sororities, however, Sigma Zeta Chi was also dedicated from the start to genuine service toward the benefit of mankind. In the 1930s, the sisters sewed blankets, collected food and raised fund for impoverished people at home and war orphans and refugees abroad. When World War II started, they organized rubber, nylon and metal drives, helped families throughout the town with their Victory Gardens, helped sell war bonds, and more.

But World War II also began to change the rules for the sisterhood as a whole. In the course of the war, with men abroad and factories understaffed, many of the sisters went to work in fields they had never even considered before. In the postwar period, the sorority began to expand its scope, taking a more proactive role in the community and encouraging its members to blaze new trails. As the decades passed, they became increasingly socially and politically liberal, and their focus shifted increasingly away from etiquette and domestics and toward charitable causes. Today, the Sigma Zetas are one of the most service-oriented and well-liked Greek organizations on campus. Their private dining room was closed over a decade ago, and now serves as a call center from which the Sigma Zetas run a free campus crisis hotline. Their dens and lounges are used more often for rallies, meetings and sign-painting parties than huge bashes, and when they do throw more 'traditional' parties, they're frequently used to fundraise for various causes. These days, Sigma Zeta Chi has little patience for Greek politics, but the sisters do frequently work with Phi Beta Tau, another relatively liberal fraternity that frequently engages in charitable work.
