Galleni Junior had his first contact with Martial Arts at the age of 4 practicing Judō for 2 years, at age 11 he practiced Tae Kwon Do and at age 13 practiced Kung-Fu Shaolin for 4 ½ years.
In 1999, at the age of 20, began the practice of Ninjutsu Bujinkan, where he continues his journey to this day.
In 2005 he had his first contact with Dai Shihan Christian Petroccello (15th Dan), a direct disciple of Sōke Masaaki Hatsumi.
On February 21, 2010 received from Dai Shihan Christian Petroccello, the name of his Dōjō:
Shinmuryō Dōjō (Place Where You Study The Truth Without Measure). Currently teaches in the city of São Caetano do Sul - SP - Brazil, also has disciples in other states of Brazil, where he travels periodically to administer intensive training.
Bujinkan cultivates peace and harmony among humans through the study of Martial Arts.
The main weapon of a Budōka is your heart; with him, the bonds of friendship are created among the practitioners and the Budō is developed with even more joy. This feeling, undoubtedly, is one of the main focuses of the Bujinkan Dōjō.
