Xi Chapter's house is located at 1411 Elm Avenue in Norman, Oklahoma. Both in-house and out-of-house members spend time at this beautiful home for sisterhood events, study parties, formal dinners, and more. Our chapter facilities include two newly renovated study rooms, three large living rooms, two large dining areas, and space for our chapter meetings.

Due to a recent million dollar expansion granted to our chapter, we have also gained a large rehearsal and presentation space, which our members use to practice for university events such as University Sing, Sooner Scandals, and Homecoming, as well as to host events throughout the school year. We are lucky to call the AOII House our home, and our members know that this is a place they can always come to see a familiar face and spend time with their sisters. 



On the evening of November 15, 1920, six women met and organized Omicron Pi, a local sorority at the University of Oklahoma. Although this was the first formal meeting, the women had this project in mind for several weeks and had corresponded with friends who were members of national chapters of Alpha Omicron Pi. The women of Omicron Pi begain to petition AOII's national headquarters in 1921, and continued every year thereafter until gaining a charter in 1924. The petition was accepted in January 1924, and Xi Chapter was installed on March 22, 1924.

Due to the Great Depression, Xi Chapter was forced to close its doors in 1933 along with many other sororities during this time. Alpha Omicron Pi International Headquarters held the charter in trust in hopes that the chapter would return some day, and continue their legacy on OU's Campus. In 2002, Xi Chapter re-colonized at the University of Oklahoma, and is now one of eleven NPC sororities on OU's campus. We are part of the South Greek community, surrounded by our Panhellenic sisters and IFC brothers, and we are proud to actively participate in many of OU's university-wide philanthropies, competitions, and events.

Since re-colonization, Xi has gained thousands of new sisters who have gone on to change the world. You'll find our alumnae in leadership positions all around the United States, in a wide range of careers, including artists, speakers, authors, entrepreneurs, healthcare and law professionals, and so much more. Our sisterhood is built on values, tradition, and loyalty, and our members pride themselves on being genuine women concerned with improving the communities around them.



AOII's commitment to diversity, equity, and inclusion comes from the understanding that a diverse sisterhood, grounded in unique perspectives and experiences, is one of the most important cornerstones of our organization.
