    Michelle "Sass N Ass" Ronsen
    Hello and welcome to 9Round Bozeman. I am the owner and so happy to be a part of 9Round and bringing this amazing fitness concept to our small town. I am very passionate about health and fitness and sharing what I have learned on my journey with others. Being a college volleyball player, sports and training hard have always played huge roles in my life. I will never forget the first day I ever boxed....I was hooked immediately. With over 12 years of training in boxing and kickboxing, I stumbled into a 9Round. I was not sure about a 30 minute workout being enough....I was wrong! I decided almost immediately that I wanted to bring this back to Bozeman. I am lucky to get to do what I love everyday while raising my beautiful children in such a positive environment. Outside of the studio I enjoy spending time with my kids and dogs, hiking, biking, being on the beach and traveling. I hope to get to meet you and show you what we have to offer here.

    Zach Cross
    Zach began his road to being fit at the young age of 14. Having lived a very unhealthy lifestyle and having a strong desire to get in shape his journey began. Expressing a love for martial arts, he had himself enrolled in karate classes reaching the rank of black belt by age 18. Looking to expand his knowledge, he quickly made the switch to mixed martial arts and full contact kickboxing with a combined 15 fights between the two. He is also a renowned martial arts coach, being ranked under many prominent instructors around the country. His passion in life is to help others along their road to fitness, having began his journey in an effort to combat obesity himself. He prides himself on his ability to not only bring out the best in his clients, but ensure they have fun while doing it. Outside of 9Round you can find him lifting weights, training in jiu jitsu and muay thai and hiking in the gorgeous Montana mountains.
