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.

Rhoers are young girls between the ages of 12 and 18 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 purpose of the Philo Affiliate is to promote the high ideals of Sigma Gamma Rho, support its programs, and provide volunteer services to the sorority and the community. The organization is made up of women who are not members of Sigma Gamma Rho but who share its principles and are committed to supporting its mission. The Philo Affiliate works closely with the sorority and often participates in joint activities and events. Its members engage in a variety of service projects and programs, including educational and cultural initiatives, community outreach, and fundraising. The Philo Affiliate also provides a platform for women to develop leadership skills, build relationships, and contribute to the growth and success of Sigma Gamma Rho Sorority, Inc.
