Mission The sisterhood of Sigma Omicron Pi was established at San Francisco State University in 1930 by ten Asian American women pursuing the interest of teaching. They chose the Greek letters, Σ, O and Π to represent themselves as the "Sisters of Pedagogy." The Constitution was derived from an existing "Honorary Society of Education." The sorority was active in the Asian Community for the next 15 years. At the advent of World War II, the organization was forced to become inactive. In 1946, a group of women from the University of California, Berkeley re-established ΣOΠ on their campus. The purpose of ΣOΠ is to promote unity, lifelong friendships, leadership, and community service. This organization offers women a supportive network of sisters to achieve academic and social growth. The sisterhood of ΣOΠ provides an environment where sisters may utilize and develop their organizational skills.
