  • to provide spirit wear celebrating our school and its symbols
  • to help lead the community by setting an example of volunteerism and involvement in school activities
  • to supplement our school's budget by providing supplies and equipment that support our school's athletic teams and our student athletes, as well as all of the GBN students using our athletic facilities
  • to help promote the positive athletic experiences that play a vital role in our children's development, and
  • to enhance the enjoyment of the GBN athletic experience for our community, our visitors and our guests.
