Michaela Matthys Assistant Coach

I started swimming when I was 4 years old (with the Lesniaks as my coaches) and recently graduated from the University of Wisconsin - Whitewater, where I swam all 4 years.  I have reached championships level meets including NCAAs, but really cherish the memories and friendships that I have made throughout my years of swimming.  My main strokes were butterfly and breaststroke. I look forward to everything coming full circle with me coaching with the coaches that taught me, being on the the other side of the sport and impacting swimmers the way my coaches impacted me.
