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; however, such challenges provide the sorority with opportunities to carry on Little’s vision.

Rhoers are young girls who are 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 grow to be women of substance who are dedicated to service.

The Rhosebud Club is an affiliate group of Sigma Gamma Rho Sorority, Inc. consisting of ..a diverse group of girls, ages 8 through 11. Delicate like the petals of a rosebud, this affiliate group is handled with special care and attention.

Sigma Gamma Rho Sorority, Inc. seeks to play a role in helping to cultivate girls as they grow into young ladies who are well-rounded and will embody the qualities needed to be good students and productive citizens. We feel this can be best achieved through action that will contribute to the overall well-being of the Rhosebud.
