About Us
Core Martial Arts and Fitness (“Core”) is a school (dojo) designed to promote positive changes in our student’s lives through the practice of Jiu Jitsu, kickboxing and other forms of martial arts.  We place a heavy emphasis on physical fitness and health, incorporating them into all of our classes.  Our instructors have a passion for training and work hard to improve their own martial arts techniques, physical fitness, and teaching skills.  We love what we do and try to reflect that in our classes and our service.  We want our clients to have a great time training and enjoy the benefits our classes provide.  We will do our very best to insure that your time with us is time well spent and that you leave our classes with a feeling of accomplishment.

What drives us
Our motivation is to share the positive effects of martial arts, health and fitness with our community.  We want to help people change their lifestyle to live a happier, healthier, and more exciting life.  We have a desire to empower people to make better choices, live with less stress, and develop the strength and ability to address their fears.

The Core Team

A brief description is in order to help prospective students get a feel for the instructors of our school.  First and foremost it is important to remember that Core is not about us, it is about you.  Our intention is not to promote our own accomplishments or deeds.  As this may have some relevance in your choice to train with us, it also does little to help with your success.  After all when searching for a school what really is important is what the school can do to help you.

Our school is about progression and our instructors reflect this mode of thinking.  We are very open-minded to adapting our programs to serve the changing needs of our students and to address the evolution of an art that will always keep growing.  After all this is the true nature of Jiu Jitsu.
