There are a few simple things that make a good martial arts school a great one. We work our hardest every day to fulfill those things, and give our students the best experience we possibly can. Here's what it takes, and what you can expect when you walk through our doors for the first time:

Knowledgeable, Passionate Instructors.
When hand-picking our instructors, we look for a few key traits: passion for martial arts, passion for teaching, a great personality, and expertise. Our instructors truly care about you and your experience. They're here for every question you have and every challenge that arises.

They'll push you to try your hardest, and motivate you to surpass your limits. Nothing beats having a great teacher - and we have the best.

A Clean, Up-to-Date Facility.
The best teachers in the world won't make up for a dirty facility with run-down equipment. That's why, every day, we thoroughly clean our studio from top to bottom. And we check our equipment to make sure it's in good working order, and replace it when it needs replacing.

Finally, it takes the right people to make an amazing community. The environment of our school attracts people who are open-minded, enjoy socializing with one another, and enjoy having fun. The parents whose kids train with us are caring and supportive. The adults who train with us are kind and fun. It's like a family here, and we'd love for you to become a part of it.

Browse around our website and learn about our programs. When you find the one that's right for you, you can sign up for a trial online and get started asap. Call and let us know if you have any questions. And I can't wait to meet you in person.

Meet Jim Rosenthal
Owner at Dayton Martial Arts in Dayton, OH

In the late 70s Sensei Jim started his combat career in the sweet science of boxing. His amateur career was 7 Wins and 1 Loss , 6 by K.O.

Sensei Jim trained in various martial arts from 1978 – 1995, but truly found his calling when introduced to the Yudansha Fighting System in June of 1995. Jim quickly moved up the belt grading system and started competing in 1997.

Jim was introduced to Renzo Gracie at a seminar that the Yudansha School promoted. Sensei Jim fell in love with the style of Gracie Brazilian Jiu Jitsu. He traveled to NYC several times over the next few years and received a blue belt in 1999 and a purple belt in 2003 under Renzo Gracie.

In 1996 Sensei Jim started training Muay Thai till 2001 under Oscar Kallet. He was the Light Heavy Weight Champion in kickboxing at that time.

In 1999 Jim opened Tenbears Martial Arts Academy, and started training harder to get his black belt in the Yudansha Fighting System. In 1999 Sensei Jim’s head instructor (Brian Johnson) in the Yudansha Fighting System moved out of state and Jim began working with Sensei Mark Connelly. In 2010 Jim began working with Marcello C. Monteiro and received his BJJ Black Belt in 2014.
