Phi Sigma Tau is the oldest sorority on the Doane University campus, and has been in continuous existence since the fall of 1907. Members are proud of their continuing traditions of leadership and service within the University and the community, unified sisterhood, close alumni ties, and the uniqueness of each individual member. The daisy is the sorority flower. Their mascot is the monkey, and their traditional colors are brown and white. Through social and money-raising activities and community service projects, the women of Phi Sigma Tau enjoy the bond of lasting and lifelong friendship and loyalty. Phi Sigma Tau is open to eligible Doane women based on individual interest and invitation.
