Koa Team Crest

Thank you for considering KOA Martial Arts as your martial arts and fitness training home. KOA Martial Arts is also known as just "KOA Team". “KOA” is Hawaiian for “warrior”; in Hawaiian, KOA can also mean brave, bold, or fearless. Professor Kelly chose the name KOA not only because of its meaning but also because of his close affiliation with Relson Gracie (Jiu Jitsu) in Hawaii. Additionally, when Professor Kelly was a Marine, he served with 2nd Battalion, 3rd Marines (2/3) in Afghanistan; the Battalion’s call sign was then, and still is, KOA. 

In honor of all of the warriors that have brought us the modern Brazilian Jiu Jitsu lifestyle, the Muay Thai 'Way', and in honor of the warriors of 2/3, our Stafford, VA team proudly carries the "KOA" name.

At KOA Team we strive to develop warriors. Warriors are responsible citizens who possess martial characteristics and seek self-improvement and to improve those around them, their community, and their society. Warriors lead by example and understand that one must commit to something greater than oneself.

Again, welcome to KOA Martial Arts in Stafford, VA. We hope you choose KOA Team to start your BJJ, Muay Thai, Mixed Martial Arts, or fitness journey. If you are already part of the team, thank you for making KOA Team your home. Remember, there is no “endstate” when pursuing the martial way. It is akin to walking a path, not reaching a destination. “Enjoy the walk.”

"Being a police officer puts you in situations where physical violence can occur while performing your duties.  Kelly Grissom's vast experience allows him to teach Brazilian Jiu Jitsu to me in a way that I am confident that I will be able to defend myself during a physical encounter at work.  Training Brazilian Jiu Jitsu with Kelly has improved my physical abilities as well as my mindset.  The one on one training that Kelly provides his students can not be found anywhere else.  Whether you are trying to get in better shape, learn self defense, or compete at the highest level, Stafford BJJ will provide you with the training you desire.  I look forward to continuing my Brazilian Jiu Jitsu journey with Kelly Grissom."

"Being a part of Stafford BJJ has been an incredible life-changing experience for me. Coach Kelly is a great guy who puts his all into helping every individual who is put in front of him. Kelly runs a great program with people that easily become like family."

"I've trained Brazilian Jiu Jitsu with instructor Kelly Grissom for about 6 months and I have to say that I haven't been in better shape since I left the Army 10 years ago.  His instruction and attention to detail are incredible as is his experience and competitive record.  If you're thinking about learning a martial art, Brazilian Jiu Jitsu and instructor Kelly Grissom's KOA Team are the best!"

"In the time that I have been training Brazilian Jiu Jitsu, Coach Kelly's martial arts values, discipline, and attitude have been a positive influence for me on and off the mat. His experience and commitment to teaching simply speaks for itself! Joining his team was easily one of the best decisions I have ever made."

KOA Team member



"Coach Grissom makes Brazilian Jiu Jitsu a rewarding experience from the moment you walk on the mat.  During his sessions, he emphasizes fitness, mental concentration, and a teamwork environment.  While maintaining a deep respect for the martial arts, he remains extremely friendly, approachable, and can teach BJJ to any type of student.  I have trained at two gyms over the past two years, and I would fight to get a chance to train with Coach Grissom again.  He brings BJJ to an entirely new arena of martial arts."

"In the few months that I have trained with Coach Kelly I have benefitted a great deal.  The physical fitness gains are amazing.  As a 19 year [career] Marine I was satisfied with my level of fitness, until I hit the mat the first time.  In addition to fitness, the flexibility gains are great.  Coach Kelly has a natural ability to teach at a variety of different skill levels and keeps the entire class learning despite different backgrounds and experience.  The history and traditional aspects of his teaching are very interesting and gives students an in depth understanding of what is being taught.  The overall atmosphere at Koa Team is very family friendly and welcoming to new students."
