unnamed (17)Philo Affiliates


Since its inception, Sigma Gamma Rho has promoted unity among women and for years many alumnae chapters worked with individuals who were not members of Greek-lettered organizations. These women were organized into auxiliaries that had various names until 1954 when the sorority officially approved the organized affiliate group and accepted the name of “Philo”(meaning Friend) as their official name.

The Philos is an affiliate organization to Sigma Gamma Rho Sorority, Inc. The Philos consists of women of high caliber, dedication, and commitment and who share the sorority’s principles of sisterhood and service. Membership is open to progressive women who are business owners, associate or technical degree holders, who share the sorority’s principles and are interested in helping Sigma Gamma Rho render service to humankind and improve the community. 

Rhoer Affiliates


A love for youth and the development of their full potential was the primary motivating factor that inspired Founder Mary Lou Allison Gardner Little to organize Sigma Gamma Rho Sorority, Inc. Young people today face challenges that could never have been imagined years ago, but such challenges provide the sorority with opportunities to carry on the vision of Little.

Rhoers are young girls organized on a local, regional and national level. The Rhoer affiliates are working to help other young people while they learn about their heritage and develop leadership skills. Sigma Gamma Rho is dedicated to helping Rhoers to grow to be women of substance dedicated to service.
