Bio


I am a former Wissota Midwest Modified National Champion. I got my start racing at a young age competing on the water, ice, snow and in cross country events while growing up and was very successful at it. I won the prestigious Eagle River World Championship and I-500 snowmobile events during my snowmobile racing career. I decided that dirt track racing was more my style and jumped in head first, in 2002 after turning 16. After several seasons testing and learning the tricks of the trade I set off in 2005 to compete on a regional and national scene. Since 2005 I have won in every type of car I have driven. My race team has a lot of drive and determination night in and night out. We have won over 100 features plus some of the biggest specials that's Wissota has.

I have three awesome kids who love racing and being at the track with friends. They really enjoy end of season specials when they also get to camp at the track.

We can't thank our Sponsors and fans enough for all your support. Without all of you backing Gronwold Motorsports we could not do what we love. Thank you all so much!
