On April 28, 1867, at Monmouth College, in Monmouth, Illinois, 12 courageous young women set the stage for a thriving organization that continues to enrich the lives of many during their collegiate years and beyond. That organization — originally called I.C. Sorosis — is now Pi Beta Phi Fraternity for Women, a sisterhood of more than 300,000 women. 

Throughout our history, Pi Beta Phi has helped young women develop meaningful relationships with others while reaching their personal potential. These relationships help sisters adapt to college life by providing a sense of belonging, mutual support and guidance. Our legacy of philanthropic service, innovative member programming, premier events and leadership development programs help our sisters become Friends and Leaders for Life.

Since 1867, Pi Beta Phi has ensured women have the support of sincere friends, opportunities to lead and the inspiration to achieve their goals. We’re proud of our heritage and honor the legacy of Pi Phis who have come before us. Sisters coming together to support each other is as relevant today as when our 12 courageous founders formed the first women’s fraternity.

Friendship has been at the core of Pi Phi sisterhood for more than 150 years. Now, more than 300,000 members strong, we cultivate relationships through shared experiences and values. We prioritize philanthropic work and maintain a century-long commitment to bettering society through literacy service. Our premier programming and member events promote personal, intellectual and leadership growth and provide Pi Phis a place to develop and practice their skills.

Our members know Pi Phi sisterhood lasts a lifetime. Whether serving as volunteers or staying connected through an alumnae club, our members remain dedicated to Pi Phi long after college.
