Theta Phi Alpha is a national women's social fraternity, and is a member of the National Panhellenic Conference. The mission of Theta Phi Alpha encompasses far more than providing a social network for college women. For more than 90 years, the sisters of Theta Phi Alpha have maintained a history rich in educational excellence, professional achievement, and a deep commitment to social service.

Steven's Colony of Theta Phi Alpha is a unique and diverse group of young women who all share the qualities of individuality, leadership, and above all, a dedication to their sisterhood. The sisters not only participate in, but also excel in many teams and organizations on and off campus. Some of these activities include Alpha Phi Omega, Society of Women Engineers, Ethnic Student Council, Engineers without Borders, Varsity Swim Team, The Dramatic Society, The Stute, The Movie Committee, APO, Gear and Triangle, Tau Beta Pi, Theta Alpha Phi, Tour Guiding, Stevens Christian Fellowship, and ASEM. Theta Phi Alpha is also dedicated to public service. Their philanthropic causes are Glenmary Home Missioner's Camp Friendship, The House that Theta Phi Alpha Built, The Theta Phi Alpha Foundation, and the  Crohn's & Colitis Foundation of America

Aside from Theta Phi Alpha’s history of vast involvement on campus, Theta Phi Alpha holds academics to the highest standards. Throughout the years, Theta Phi Alpha has earned a reputation for high academic achievement by often obtaining the highest grade point average of all Greek houses.

Steven's Chapter of Theta Phi Alpha stemmed from a local sorority known as Omicron Pi. Omicron Pi Sorority was founded in 1987 by a group of eight women who were formally little sisters of the Alpha Sigma Phi Fraternity. They broke away and formed their own sorority. They then became a local sorority at Stevens and its love grew each year for 25 years. In the year of 2010, the sisters and alumnae of Omicron Pi decided to expand and become a part of Theta Phi Alpha, an NPC organization.

The sorority recognizes Saint Catherine of Siena as their patroness and it is from her their motto, “Nothing great is ever achieved without much enduring” is originated. This motto best encapsulates the qualities present in the sisterhood. In conjunction with their motto, the sorority symbol is the compass. By tradition, the compass leads sisters on a path of achievement and success. The sorority’s colors are blue, silver and gold, and sapphire and pearls are the sorority's jewels. The White Rose is our sorority flower.

Whether you are a parent, college student, or administrator, we encourage you to take a few moments to read about our mission, history, creed, and traditions. The outward signs of our Fraternity - our symbols and insignia - will complete the picture. Membership in Theta Phi Alpha, like that of any other NPC sorority, is lifelong. We encourage you to choose the sorority that best fits your long-term goals.
