Junior Coaches:


Chris Jesten

My name is Chris Jesten and I have been swimming with Rolling Valley for 10 years.  When I first started with the Dolphins, it took me one minute and 11 seconds to swim 25 meters.  I now swim with SDS Swim club year round and have made the High School Swim Team every year. Swimming is a life skill and I firmly believe that if you practice and believe you can improve, you will.   I have coached Winter Swim for the Dolphins for the past two seasons and before that I volunteered to get my service hours by coaching our younger swimmers. If you see me in the lifeguard chair at the Rolling Valley Pool, please say Hello.  I have been a lifeguard for two years. I am a lifeguard and a dog sitter and love all music - I even play a few instruments!

Chris can be reached at 703-887-9169 for private swim lessons.


Lars Griffin

My name is Lars Griffin and this is my second year being a Life guard. I go to West Springfield High School where I swim and play lacrosse. Some of my favorite things to do include hanging out with my friends and playing games. One fun fact about me is that I have never met Keanu Reeves.
