Coaching Staff

Kerry Fliedner

Head Coach


This is my fourth summer coaching for the Holly Park Sharks, but I've been part of the team for six years. I have been swimming for a majority of my life, and I've always loved being around the pool scene. I'm currently going to Metro State and getting my bachelors degree in Exercise Science, with only one year left! I'm looking forward to this summer and another year! Lets go Sharks!

Charlie Downing

Assistant Coach


I just graduated from Littleton High School and plan on attending CSU this fall. I swam for a little over 10 years with both Columbine Country Club and Aces Swim Club. I have a passion swimming and love spending my summers by the pool. I can't wait to become part of this amazing team and have an awesome summer! Go Sharks!

Isabella Bertaud

Assistant Coach


Hello Everyone! My name is Izzy Bertaud, I am currently attending Carthage College in Wisconsin, but I’m returning to Colorado for the summer! I have been with the Holly Park Sharks since 2007. From there I was inspired to begin my club swimming career with Aquawolves. I began Aquawolves in 2012 and continued until 2018. Within that time I also swam 4 years at Cherry Creek High School, 2 years on JV1 and 2 years on Varsity. Most Recently I have completed my first season as a Collegiate swimmer as well as a Collegiate Water Polo player. This past semester I have been teaching lessons every week to swimmers of various ages and levels. I am looking forward to my very first coaching experience with the Holly Park Sharks and I am excited to help my swimmers grow!
