Jessica Mlachnik

Bachelor’s Degree in Sport Management, St. Ambrose University

Growing up, Jessica, was always involved with sports and other activities it was nearly impossible to get her to sit still.  Her love to be active and participate in sports only grew stronger as she got older it had a lot to do with her passion and drive, also her very large family who were also involved with numerous sports and activities.  In high school she played as many sports as she could, whether it was for the school or for club teams outside of the school. That love she had for competition carried over into college. Jessica attended St. Ambrose University in Davenport Iowa where she competed on both the Women’s Basketball and Soccer team all while completing her Bachelor’s Degree in Sport Management.  Throughout her college years she coached numerous teams and helped out with a few speed and strength programs. During her summers she would come back home to the City of Muskego where she helped coached girls soccer and basketball at the high school level. She would also coach her own AAU basketball teams for both boys and girls at a few different age levels. The speed and strength program she helped out with consisted of high school aged student athletes from all levels and all different sports.  Meanwhile Jess has great experience working with student athletes at all ages, she also has experience working with people of all ages and all abilities with fitness and sports goals. 

In her free time she is still active with sports, she participates in coed soccer, volleyball, and softball leagues in her free time, as well as still coaching on the side.  She also likes to relax and hang out with her family and friends any chance she can.

What Our Clients Say

Josh is amazing ! Thanks to his training I was able to reach my initial fitness goals. He continues to push me with every session and the amazing results keep on coming.

Denis C. Racine, WI

“My husband and I started training with Josh six months ago because we wanted to get healthy and fit but were intimidated to go to a gym because we didn’t know how to work out and were intimidated by other “gym rats”. We enjoy the one on one sessions in his private gym and Josh’s expertise is phenomenal, creating workouts tailored for your goals that are challenging and always changing. My husband and I would recommend Josh as he would be an asset for anyone looking to improve their health regardless of their current fitness level. He is a great trainer who cares about his clients.”

Laura K. Oak Creek, WI

“I started with Josh and Impact Fitness in March of 2010. Previous to Josh I had another personal trainer for 1-1/2 yrs. Josh has done more for me in the last five months than I thought anyone could. He continuously challenges me and pushes me further than I ever thought I could go. He has more confidence in my abilities than I do and he makes sure I prove it to myself in every work out. Since I have been working with Josh, I am much more toned and fit. I see Josh for one hour two times a week, I wish I could do more. I am amazed on how far I have come with Josh. THANK YOU JOSH! You really know your stuff!”

Having an office job and a high alcohol tolerance (thanks UW) led me down a pretty sad path.  But now I’m happy to be on this beautiful fitness journey.  Thanks to Impact Fitness Studio for kicking my butt into gear.
