Connie Polnow
Coach & Administrator
Coach Connie swam for the Nereids for 8 years, starting at 9 years old. She had the opportunity to compete in several national competitions and received 9th place in the Team event at the 2013 Age Group National Championship. In college, Connie swam for her school's club swim team, where she also had the opportunity to compete nationally, and coached for the Nereids during her breaks. Upon graduating in 2019, she began coaching for the Nereids full time. Her favorite part about coaching is seeing the swimmers grow over the years and spreading the love of a sport that's been such an important part of her life.
