Imagine it—a program that brings girls together through the bond of sisterhood.

Gamma Sigma Girls® (GSG) is a sorority-type mentorship and leadership development program for high schoolers. Founded in 2010, GSG lets girls explore common interests in a safe space, discover their passions, and make new friends. Its sister chapter, Gamma Sigma Pearls™, supports middle schoolers and is named after a jewel significant to the Girl Scout movement. 

GSG is a unique program offered by Girl Scouts of Southwest Texas that brings the proven outcomes of the Girl Scout Leadership Experience to area school districts. Unlike other extracurricular activities at school, GSG does not require members to have a special talent, skill, or minimum GPA.

You just have to be a girl. That’s it!

Gamma Sigma Girls® serves nearly 800 teens in 17 high schools and nearly 1,000 girls in 19 middle schools in San Antonio ISD, Harlandale ISD, Southwest ISD, Edgewood ISD and Uvalde ISD. 

As Gamma Sigma Girls® and Gamma Sigma Pearls, teens will choose to focus on one of three areas: advocacy, taking action, and being college bound.


Advocacy: Girls will identify a cause they are passionate about and work toward effecting social change.


Take Action: Girls will become positive change agents in their community when they participate in service projects that benefit the world around them.


College Bound: Girls will explore opportunities to help them decide on a career path, and work toward achieving a higher education.

The nearly 1,800 new and returning members of Gamma Sigma Girls® and Gamma Sigma Pearls were inducted at formal Investiture and Rededication ceremonies at the beginning of the school year.
