What is Hockessin Athletic Club? HAC is a place where 400 employees, 8000 adults, and 4000 children come together to form a community that is health conscious, family-friendly, and fitness focused. We strive to not only empower our internal community, but to also be a supporter of the community in which we reside. We enjoy watching your children grow and aiding in their education, giving you a much-needed place to de-stress from our ever-busier and more-connected lives, and celebrating your goal-achievements and fitness successes. HAC is what the people who come here make it, and we think that’s pretty darn special.
