The Titan Booster Club has a proud, decades-long history of supporting the student athletes at Glenbrook South High School.  We are a non-profit organization of volunteer parents who assist in the advancement of interscholastic athletics and as an integral part of the education experience.  Through our fundraising, we help to assure our students of a first-class athletic program while also benefitting every student enrolled in physical educations classes and the summer athletic programs at Glenbrook South.

We support over 1800 students participating on 29 athletic teams.  Since 2010 , the Booster Club has donated over $2,000,000 of your donations back to Glenbrook South HS.
