Michael J. Rosenbaum began his martial arts training at the age of five. At the age of fifteen, he began studying Isshin Ryu Karate. By the time of his seventeenth birthday he had been introduced to the Burmese fighting art of Bando.

Seeking to advance his knowledge of the Burmese fighting arts, Rosenbaum, in 1990, began studying with Allan Thompson and Edward Francisco, both of whom were students of the late Bando pioneer Bob Hill. Thompson was also the founder of the Tiger Hand/Tiger fist fighting system.

Two years later, Rosenbaum went on to found the Snow Leopard Boxing/Tiger Fist system. Michael has conducted numerous self-defense and rape prevention courses as well as having been a body guard, bouncer and instructor of law enforcement personnel.

A 3rd degree Blackbelt in Isshin Ryu, with over twenty-five years experience in the art, Michael continues to practice and deepen his IsshinRyu Karate, while developing his Snow Leopard system.
