WE ARE D1 & ONLY MARTIAL ARTS
OUR FOCUS ISN’T ON CREATING WORLD CHAMPIONS. WE FOCUS ON DEVELOPING LIFE CHAMPIONS!
The mission of D-1 & Only Martial Arts is to cultivate the minds and bodies of our students and to help and encourage them to be and to do their absolute best. We provide a fun, family-oriented, positive and safe environment for our students. We help shape and nurture the character of our youth, teaching them discipline, focus, respect and self-control. We work towards developing healthy, fit, intelligent and successful students.
We also ensure that our diverse program provides our students with the ability to defend themselves from a variety of dangerous situations based on modern and real-world scenarios. We’ve taken a different and innovative approach to self-defense by combining techniques, principles and theories from Krav Maga, Kickboxing, Basic Brazilian Jiu-Jitsu and Arnis. Our curriculum provides our students with the ability to defend themselves standing, on the ground, against multiple attackers and attackers with various weapons.
In addition to our realistic curriculum, our focus on character development and our emphasis on fitness and healthy living, we provide fun and free monthly events for the kids, amazing life-skills programs and so much more! We aren’t your average martial arts school and we don’t want to be. We’re D1 & Only Martial Arts!
