Kiefer Stellwagon Assistant Coach
My name is Kiefer Stellwagon. I am the Silver coach for Lawrence AquaHawks. I was hired with the team in December of 2024 where I helped Coach Meredith with Bronze and moved up to Silver last Spring. In high school, I swam competitively my junior and senior year.   
 
Prior to my time with Aquahawks, I've been a Red Cross lifeguard for 13 years. In that time, I worked for a summer camp in Bonner Springs before going to work at the Lawrence Indoor & Outdoor Pools. In 2022, I became the assistant supervisor of the Topeka Hummer Natatorium and now have my own staff of lifeguards. I also teach swim lessons there and lifeguard certification classes. 
 
Outside of work, I'm working on my Master's degree in Sports Management and Recreation and will be graduating in June of 2026. 
 
My favorite sport is soccer, even though I've never played it. I'm a big fan of the KC Current and the KU women's team and have season tickets to both. I love motorsports (my favorite is Formula 1), movies (Moonrise Kingdom is my #1), and space exploration (I dabble in astrophotography). I've traveled the country for sporting events, to watch NASA launch rockets, and for pleasure.
 
I love my jobs and can't envision myself spending my time any other way!
