Sigma Gamma Rho Sorority, Inc. was founded on November 12, 1922 in Indianapolis, Indiana by seven young educators. The group became an incorporated national collegiate sorority on December 30, 1929 when a charter was granted to the Alpha chapter at Butler University. Sigma Gamma Rho is the only sorority of the NPHC not founded at Howard University, but at a predominantly white university. The organization is devoted to sisterhood, scholarship, and service. The Rho Omega Chapter of Sigma Gamma Rho was chartered on the JHU campus on March 15, 2009. Nonetheless, there were SGRhos at JHU in the former Gamma Mu City Wide Chapter chartered in 1968.
