The Greendale Panther Athletic Booster Club was established to promote and encourage a continuing spirit of enthusiasm in and for the Greendale High School athletic program. Specifically, the non-profit civic organization engages in activities which:

• Financially and physically assist the Athletic Department and the Athletic Director.
• Develop between educators, parents, and the general public, united efforts in order to secure the highest advantages for the Greendale High School student athlete.
• Raise funds in a non-political and non-sectarian manner, which are used to benefit all Greendale High School athletic teams and programs.
• The GPABC has contributed over $500,000 since 1999 to help fund Greendale High School’s 22 boys and girls athletic programs, and facilities.
