letter from our president


Welcome to Alpha Chapter!

On January 2, 1897, our four founders—Stella, Bess, Jessie, and Helen—met in Columbia’s very own Low Library to establish a fraternity to emulate the strong friendships they found here at Columbia. They sought to establish an organization that was unique in its acceptance of diversity, desire for lifelong friendship, and commitment to service. At its core, AOII devotes itself to loyalty, sincerity, kindness, and love. That our founders pledged themselves to each other here at Columbia over 120 years ago makes it all the more special. As I look at each member of AOII, I see loving sisters carrying out our founders’ legacies with warmth and grace.

Joining AOII has been a life-changing experience. I have met incredible sisters who are supportive, lively, and dynamic. My sisters are there for me at all times and challenge and empower me every day. Trust me, a sister will always have your back. AOII has shown me that there are so many outstanding and passionate women who come together to “Inspire Ambition”. I am proud to be a part of this warm and welcoming community that encourages our growth as leaders and sisters.

Please explore this page to learn more about our sisterhood and philanthropy. My hope is that you all find the same love, strength, and inspiration from AOII that I have myself. I promise—there’s something truly spectacular to be found here.

Alpha love and all of mine,



The first chapter of Alpha Omicron Pi’s rich history began here, at Barnard College of Columbia University in New York City. Barnard was the first college in New York where women could receive the same rigorous and challenging education that was available to men. From the very beginning, Barnard was a place that took women seriously and challenged them intellectually. The idea for such a place as Barnard was bold for its time and it was in this setting that another bold endeavor developed. Barnard’s “Great and Glorious Class of ‘98” included four particularly outstanding women: Stella George Stern (Perry), Jessie Wallace Hughan, Helen St. Clair (Mullan) and Elizabeth Heywood Wyman. These women were destined to leave a great mark both on their college and on a new fraternity they would create and embrace for their lifetimes. So, from within the great history of Barnard College emerged the grand testament to friendship, scholarship, and service that was to become Alpha Omicron Pi. Stella, Jess, Helen, and Bess became four firm friends determined that their friendship should last a lifetime. In their junior year, on December 23, 1896, the four climbed the stairs in a small gallery of the old Columbia College Library (now Low Library), which led to an old and seldom used room, where the four pledged to each other.

On January 2, 1897, Alpha Omicron Pi was formally organized at the home of Helen St. Clair. Soon afterward, the four pledged AOII’s first initiate to AOII’s Alpha Chapter, Ann Richardson Hall. Over the next 100 years, we are proud to say AOII has expanded across the United States and Canada, adding to its ranks 204 collegiate chapters and over 155,000 initiated members. After Greek Life at Columbia was abolished in 1914, Alpha Chapter was finally reestablished in Spring 2013. 118 years since our founding, Alpha Omicron Pi boasts the most collegiate chapters of any other Panhellenic sorority in North America, and we are honored that this amazing organization all started on our campus. Wherever you go, you are bound to find a sister somewhere! Alpha Chapter is beyond privileged to be able to keep our Fraternity’s rich traditions and rituals alive today.
