About Us

In the Beginning:

Ronin is a Japanese term for an outlaw or masterless Samurai. 'Ro' meaning wave and 'Nin' man, the word literally means "man tossed around like a wave." The Dojo was founded by men in a state of chaos. Discontent to subscribe to just one art or method of training, they learned and tested many. Drawing on Okinawan Karate, Ninjutsu, Akido, Muay Thai, Boxing, SIlat, Kali, Brazilian Jiu Jitsu, Catch Wrestling, Bujutsu, they engaged in no holds barred training before the UFC and the Gracies transformed mixed martial arts into a mainstream phenomenon.

For the first decade the teachers and their students were a rag-tag underground group of fighters and rule-breakers. Their reputation was for intensity, pushing limits, and a voracity to test everything. From the fires of this group the art began to take shape.

The Growing Years:

As the school grew, its distinct nature began to become apparent. This nature was about being  a training grounds for life. Here students came to learn that the limits they believed they were bound to didn't exist, and that the human capacity was far beyond anything they'd ever imagined. A return to nature, a de-evolution to states of harmony and primal strength fueled the art and those who trained in it.

Martial arts was a vehicle that encompassed warrior training on many levels. Mastery of movement became the study of working with opposing force through the fighting arts. Mastery of breath and self through Lung Gom, meditation, and tests by the elements of nature expanded students awareness and control. Wilderness survival, attunement, and tracking brought them directly in touch with nature and the place humankind holds as a part of the larger whole.

Where we're going:

It is time to share the lessons of the past and ride the wave that has been building for 20 years into the future with the Fort Collins community. The Dojo opened its doors in 2013. It is in a beautiful location, with forests, ponds and the Poudre River right outside as our training grounds. From this humble beginning it is our mission to enlighten the Fort Collins Community to the mental and physical benefits of combining martial arts, yoga, and fitness into one harmonious lifestyle.

This is a way of life, a path to getting more out of everything. The way of the warrior is not the sole domain of young men. It is about creating strength and harmony through personal cultivation. Through our synergistic programs of Martial Arts Fusion, Vana Flow Yoga, and Sarasya Tone fitness along with the other programs offered you can find yourself more balanced and centered, healthier, and capable. Come in and see what we are about for yourself.

Team Bio:


personel bio picRandall Brown, Head of the School: In 1993 Mr. Brown was awarded the rank of Soke (headmaster) by the Zen Kokusai Soke Budo Bugei Remmei, a traditional martial arts organization with branches in the US, Okinawa and Japan. This rank was the result of his thirty plus years of training in various martial arts but dealt exclusively with his training in the traditional bugei (warrior) systems of Japan. Not long after this the ZKSBBR made it clear that any of the traditional martial artists who competed in non-traditional competitions (mma) would have their rank and status revoked. Because his students have won both mma and grappling world titles, Mr. Brown has been disassociated from that organization for over 15 years. He no longer acknowledges his traditional titles or belts, and has not identified the arts taught in his school as Akumu Ryu in well over a decade. At this time he continues to train black belts and fighters while focusing on the C.O.B.R.A. self defense system.
