Anttonen Natatorium is housed in the same building as the gymnasium was renovated in 2011 and received additional upgrades in 2019. The renovations included new bleachers with seating for 500 spectators, lighting, blocks and timing devices. It has been the home of the women’s swimming program since its inception in 1976. The facility was renamed and dedicated in 2018 in recognition of the generosity of Ralph and Judy Anttonen.Â
