Gamma Phi Omega International Sorority, Inc. began with Veronica Montemayor, who in the fall of 1989, first thought of the idea for a local Latino-oriented sorority. After considering Indiana University's traditional Greek system, Veronica felt that the Greek community did not offer enough for Latina women. She decided that it was time to create a new option, one that celebrated the diversity of the Latino culture. Veronica, joined by Monica Guzman and Cristina Rodela, began a nationwide search to find a Latino-oriented sorority that wanted to expand to Indiana University. They were looking for a sorority that strived for the goals and objectives they felt were important for a Latino-oriented organization: academic excellence, cultural awareness, community service, and sisterhood. The search was not easy and lasted a full year. The following semester, Margaret Escabalzeta, Laura Garcia, and Barbara Graves joined the three women. After continued research, few sororities fit the desired sorority the women were looking for.

     At that point, the women decided the best option remaining was to start a new sorority. The women were granted permission to work on an Alpha Chapter, on the Indiana University campus. On April 17, 1991, the 6 women, Veronica, Monica, Cristina, Margaret, Laura, and Barbara, founded Gamma Phi Omega International Sorority, Inc. Veronica Montemayor graduated that spring of 1991 and was unable to accompany her new sisters to present their final proposal for Gamma Phi Omega to the University's Expansion Committee. Nevertheless, her dream became a reality when on January 22, 1992, the core group received an acceptance letter recognizing Gamma Phi Omega as an official sorority on the Indiana University campus.
