Mark Steven Grove began training in martial arts in 1972 and has spent his life pursuing the art of the Ninja.

In the late 1970’s Mark Grove met Shihan Frank J. Goody Jr., a Master of multiple martial arts, including Nagai Ryu Jujutsu, Matsuyama Ryu Yawara, and Kota Ryu Ninjutsu. In 1981 Mark and Shihan Goody were able to reunite and Mark received a huge volume of information about Kota Ryu Ninjutsu including 16 unarmed techniques with four variants each, scrolls related to the art of mysticism called Gorin Kuji Myo Himitsu Shaku, and in-depth information about the art of joint manipulation and striking using a short handheld stick.

Mark Steven Grove had the honor of studying with Small Circle Jujitsu founder Professor Wally Jay.

In 1987 Mark Grove was asked to become a member of the Samurai Society of America, an organization comprised of highly regarded and qualified instructors willing to share their knowledge and experience for the benefit of all martial artists. At this event Mr. Grove taught short staff grappling techniques and elemental meditation.
Always seeking after knowledge and looking for an outlet for his skills, Mark Grove created a new path for his skills and began learning all aspects of fight choreography and cinematic technique under stunt coordinator Lars Lundgren. This allowed Mr. Grove to utilize his skills as an actor and stunt performer in the film industry.
In 1994, Mark Steven Grove has had four years of apprenticeship in the stunt industry working on many projects as an actor and stunt performer and he decides to open a new training facility that focuses on what he calls American Chambara to pay homage to the epic Samurai an Ninja films from Japan.
