Coaching Staff

Ethan Daniel Sellers

Head Coach/Head Senior Coach


Ethan joined the sport of swimming at the age of 9. Swimming in Minnesota at the time, he quickly learned that this was going to be his lifelong sport. After a few years of training, Ethan had become nationally ranked for his age group in the Breaststroke. He started competing with the varsity high school swim team in 7th grade and swam throughout high school, qualifying and competing at Zones and State many of those years. Ethan started coaching for the team he entered the sport with in Minnesota. He later spent time as a part of New Berlin Swim Club’s coaching staff, and now is extremely excited to coach the Senior group of SWMKE.
