Welcome to Student Activities

With over 80 clubs and organizations, we challenge you NOT to find something that interests you!

Glenbrook South High School prides itself in its expansive offerings through the areas of the four A's: Activities, Arts, Athletics and Academics. This webpage serves as a hub for all things Activities-related; however, we realize there is often overlap with Arts and Academics. We encourge you to explore those department webpages as well.

About the "SAO" - Student Activities Office

Whether you are passionate about an interest or simply want to find something new, we believe that there is an activity for everyone at Glenbrook South. We encourage you to search our website for information on the large variety of clubs and organizations that we have to offer. With over 90% our student body participating in extracurricular activities, we pride ourselves on how involved our students are both in school and in the community. Research has shown that students involved in activities not only perform better academically, but have a better emotional experience in school. So.... what are you waiting for?! Find something that interests you and get involved!

If there is anything that we can do to help you on your high school journey - please stop by the Student Activities Office (located directly across from the East Cafeteria) during your free period.

We look forward to seeing you involved at South!

Glenbrook South, your spirit will inspire us to the end
And we will fight to never lose our hold!
If we win or lose, we’ve given all we had
To proudly see our flag unfold!
And in victory your name will ring throughout the land
And we’ll be proud to shout your praises true
So let’s cheer for the blue and gold of brave Titan heroes,
Glenbrook South, hats off to you!

V-I-C-T-O-R-Y! Victory, Victory, Glenbrook High!


Oh Glenbrook South we honor you
We pledge our loyalty.
To strive to bring glory
Through our ability.
Tomorrow and forever we’ll
All remember you;
Our fighting Titan spirit
Will always see us through!
