Coach Ann Peterson

Coach Ann is the team administrator, summer lessons coordinator, and assistant coach.  She usually coaches the swimmers who are new to competitive swimming in the 8Under and Intro groups.   

Ann grew up swimming at Wakonda Country Club and lettered her freshman year at Dowling.  After that season she realized her passion was not in competition but in teaching others to love the water.   Since then, she has taught all ages from baby and me classes to adult learn to swim with a few group exercise classes too.  She coached for the Manhattan Marlins in Kansas during college and coached Riptide from 2016-2018 returning in 2021.

Ann is always ready to hop in and work with kids, especially her own.  In addition to swimming she has coached her kids in volleyball and basketball.  She enjoys working to develop skills in young kids and watching the lightbulb turn on.  Her coaching style is loud and cheerleader-like, inspired by a Johann Wolfgang von Goethe quote, "Instruction does much, but encouragement does everything."         

Ann wants everyone she coaches to be a swimmer for life. She still swims as often as she can, teaches lifeguard classes, and also teaches lifeguard instructor classes.  Some of the high school aged swimmers may have been lifeguard certified by Ann or might have her husband Lance as their DCHS Spanish teacher.
