Changing lives one signature at a time.

Each year, our chapter holds its annual¬†philanthropy event Get On The Ball, in which a large beach ball is rolled around on campus and in downtown SLO. People stop by and sign the ball throughout the day, and local businesses donate money for each signature the ball receives. All of the proceeds from this event go directly towards Mateo Cota, a local seven-year-old battling Acute Lymphoblastic Leukemia. Philanthropy with ZBT isn’t limited to Get On The Ball, though; we are involved throughout the year in other philanthropies, requiring each of our brothers to support at least one per quarter.
