Welcome to TNT Martial Arts – Hillsboro! On our front door are the words: “Welcome home. Walk right in and have some fun!” That’s the kind of vibe you’ll find here because we want everyone in our TNT tribe to feel safe and comfortable being themselves – including you!

TNT is proud to be a family-based and supportive environment, free of unwholesome trolls that lurk in our society. We train our members to not be victims, but to defend themselves when they must, with the best tools available for the task. 

We support and encourage parents to be the protectors of their family and provide an abundance of reality-based training opportunities and support to your entire family so that you all can be leaders in your community. There are no victims here, only Warriors and Champions (and an occasional Jedi or Wookie may pass through too).

At TNT, we strive to be much more than just a kick-and-punch school! We are always looking for ways to enhance your learning experience… so you bring the goals list and we’ll handle the details.

Students use our classes as a highly effective training tool for personal defense, a stellar boost to weight loss and fitness gains, or even as a stand-alone martial art. No matter what age or fitness level you are, Martial Arts does wonders for your body, mind and spirit. It gives you…

  • A total body workout and extreme fitness
  • Tremendous focus, clarity and confidence
  • Increased strength, flexibility and coordination

Your Goals Are Our Goals… so if Martial Arts is totally NEW to you and you’re a bit nervous about starting, fear not! You’ll be in good hands here and will get a ton of professional and moral support from the friendly instructors and students. 

We’re one big happy family and we’re all here as your friends to support and encourage you. You’ll see a lot of smiles, laughter and high fives because we all have a lot of fun here! Where else can you learn exciting things while having such GREAT FUN?

Our children’s classes provide challenging lessons — lessons that give your child the foundation to SUCCEED and the strength to EXPLORE. This character education program invites your child and all students to listen, share, discover and reflect on the ways to become upstanding members of our community, as well as confident individuals.

Chief Instructor

Mark Gajdostik is the owner of TNT Martial Arts. His lifelong journey in martial arts began with karate in 1983. Ten years later, he watched his first ultimate fighting event when he was working on making his curriculum more self-defense oriented and that 's when he knew that even though he had already earned Black Belts in separate styles of Taekwondo, he would begin to study the art of Jujitsu and incorporate it into his curriculum.

And that 's what he did. In 1994, he began training in Jujitsu. He also began developing and teaching Police Control Tactics & Combatives, and over the 10 years while he was a police officer, he applied ALL of his skills from verbal to physical in real life, so you can say that he was doing "Mixed Martial Arts,” even before it was a household word!

Since 2006, TNT has been in Hillsboro, training men, women, teenagers and children in family-friendly Mixed Martial Arts...not just for competition, but for real life. Our focus is building Black Belts from the inside-out with our self-defense focused curriculum, character education programs, and a focus on personal core values...you know, the kind of things NOT encouraged in society nowadays.

So with the help of his assistant instructors, we run a truly awesome school, and have some serious fun! We are convinced that you 'll find our Martial Arts Program to be the best in Hillsboro because we provide the mental, physical, and emotional skills that NO OTHER sport or program can offer…and we want to share that with YOU!
