What does the Booster Club do??? Just as the name suggest, we strive to BOOST the excitement for JCA and all our extra curricular activities. Our fundraisers support any needed improvement to our gym, fields, and concession areas. Because we work hard to support all sports and student athletes from K4 through 12th grade, all parents of all athletes are encouraged to join our Booster Club so that we can work together in this great endeavor.
