HAC Athletics
The HAC athletics program provides a variety of team sport experiences, including 19 varsity, 10 JV, and 12 modified teams that help develop teamwork, sportsmanship, and good citizenship. We focus on establishing healthy habits that prepare students for the future, and fully support the physical, mental, and social development of each student athlete, as well as how to win and lose gracefully - skills that will benefit our students far beyond their time at AC.
