Words cannot express how amazing this place is!! If you’re thinking about joining or signing kids up DO IT!!"

"Best place in the Twin Ports to learn mixed martial arts for any application whether it be amateur or professional fighting in any ruleset, including kickboxing, boxing, BJJ, or for self defense. Coach Robert trains with real life scenarios in mind, and has vast experience with MMA. He also puts on great live event promotions through his school, bringing the viewership of the spectacle of a sport to the Northland in a great and family friendly way."

"Inner Strength Martial Arts is both a family friendly place for kids to learn and train as well as a place for adults to come together and learn skills in Jiu Jitsu and Karate under the capable care of Professor Mrotek. My son chose karate and jiu jitsu while his brother chose boxing, which occurs at the same time downstairs. Cleanliness, respect, encouragement, good sportsmanship and excellent martial arts skills are all part of the program at ISMA. I am extremehly happy with the choice to select this place of learning for my children. I have enjoyed watching the kids train so much, I am going to start training there myself!"
