The To-Shin Do martial art is focused entirely on realistic and effective self-defense. In the 1970’s Stephen K. Hayes became the first American to ever study the authentic and legendary Ninja martial arts with the 34th generation Ninja Grandmaster. After decades of studying and teaching the historical methods and techniques An-shu Hayes began to adapt this historic approach to be more applicable in the modern day. The result became the unique and unparalleled martial art and personal development programs which he formalized in 1997. He gave this powerful and holistic approach the title To-Shin Do, the way of the heart and the sword. Symbolically the sword represents the tools of power, which are technique, strategy and skill, the heart represents the wisdom to use these tools of power responsibly. 


Master Mark Sentoshi Russo has studied with An-shu Stephen K. Hayes since the early 1980’s. Quite often he followed An-shu Hayes across the country and the world in order to pursue his training. On a number of occasions he has, as well, travelled to train with 34th generation Ninja Grandmaster. His career in martial arts began at the age of 8 and has spanned more than 50 years. In that time he has earned teaching licenses in six different martial disciplines. At 8th degree black belt he is the senior student of An-shu Stephen K. Hayes and is the highest ranked To-Shin Do Master Instructor in the world.

A firm believer in balance and education Master Russo also holds a Masters Degree in Business Administration and Transpersonal Counseling.
