Celebrate the legacy of Mary, Mary and Martha as we remember the Founding of Phi Mu Fraternity. Phi Mu was founded March 4, 1852 at Wesleyan College in Macon, Ga. and is the second oldest sorority in the nation. Phi Mu provides social opportunities, a support network, and personal enrichment resources to members for over 150 years.  In that time over 175,000 Phi Mu women have been vibrant members of college campuses and we have chartered over 228 chapters.
