Sigma Alpha is a professional agricultural sorority that promotes scholarship, leadership, service and fellowship among its members. The sorority was founded in 1978 here at the Ohio State University by five women who wanted an alternative to the social Greek sorority system. Since that time, Sigma Alpha has become a national organization consisting of more than 80 chapters, comprised of undergraduate and alumnae members. Today, more than 6,000 members have been initiated into Sigma Alpha Sorority. We're growing steadily as others in agriculture learn about us.

Sigma Alpha is a member of the Professional Fraternity Association (PFA), a national organization of professional Greek letter organizations and The Consortium of Collegiate Agricultural Organizations. Both Sigma Alpha Sorority and the Sigma Alpha Alumni Association are affiliates of American Agri-Women. We support Ag in the Classroom as our national service project.

You'll find Sigma Alpha members standing out as leaders on their campuses and in the workforce. We are dedicated to the motto: Women Excelling in Agriculture.
