On November 11, 1874 four women at Syracuse University came together to form a society they named Gamma Phi Beta. Helen M. Dodge, Frances E. Haven, E. Adeline Curtis, and Mary A. Bingham were courageous risk takers who sought to create a society for women in a man’s world. Though at the time women’s societies were given the same name as their male counterparts (fraternities), Dr. Frank Smalley coined the word “sorority” especially for Gamma Phi Beta.

Over 140 years later, we still cherish the same ideals that our founders worked to achieve: personal worth, service to humanity, intellectual growth, and lifelong commitment. These ideals have become our Sorority's four core values of love, labor, learning, and loyalty. Today, Gamma Phi Beta is an international sorority that has welcomed over 150 collegiate chapters into sisterhood and almost 300 alumnae chapters in the United States and Canada. Our organization has nearly 200,000 collegiate members worldwide, and is still growing. As members, we take pride in our organization's rich history and tradition, and hope to share it with many more young women throughout our years.

Gamma Phi Beta seeks to provide its members with an environment that can nurture all of its members while working towards our organization's mission: To inspire the highest type of Womanhood. We constantly encourage our members to set high standards for themselves personally, intellectually, physically, and spiritually, while providing a sisterhood to help them along the way.


Here at Cal Poly, the Delta Theta Chapter of Gamma Phi Beta was founded on January 18, 1975 and has continued to grow in size and strength. The Delta Theta chapter continues to exceed the expectations of earlier sisters by excelling in academics, sports, philanthropy, and involvement on Cal Poly's campus. However, members always remember the strongest attribute of Gamma Phi Beta: Sisterhood. Although there are over 200 members in the Cal Poly chapter, every sister is dedicated to strengthening the bonds between each member which epitomizes the ideals of the organization
