Mr. Arnaldo Rosas was born in South America, in the country of Chile. He started training in the martial arts in 1977. He had always aspired to become an expert in karate as well as to master the art of weapons ever since he was only five years old. However, at that time Chile was having political problems. It was under martial law which forbid any training in the martial arts of any kind. As a young child, Mr. Rosas was frequently bullied by gangs, which increased his desire to learn how to defend himself.
When Mr. Rosas became a young teenager, the political issues in Chile had improved and he was able to start his martial arts training. He began with Kyokushin Kai Karate (full contact martial arts). In the same year he joined a second school where he was trained in Shotokan. Eventually, he became an instructor at the Shotokan school and was put in charge of teaching at a local high school, then at a local college. Mr. Rosas had truly found his passion. He began to train 6 days a week after school and began participating in numerous national and international martial arts tournaments at which he won several of the karate and kickboxing events.
Later, the Chilean government went through more changes again and began drafting men into the military. Mr. Rosas was put into the army where he trained in the art of Ninjitsu and knife combat as well as other forms of combat and self-defense.
When he was released from the army he continued his college education in addition to his training in the martial arts.
In 1990, at the age of 26, Mr. Rosas came to the United States where he was invited to train students at a Shotokan School for the world championships in Ecuador. By this time Mr. Rosas held three black belts in South America. (Kyokushin Kai, Shotokan and Karate Do). Since moving to the U.S. he has been trained in the Martial Arts of Budo Tai Jutsu, Tae Kwon Do, Aikdo, Hopkido, Ju Jitsu, and Kyusho Jitsu. He is also trained and has earned his 2nd degree in Iai Tate Do Doushi Rensei Kai (Japanese Sword).
In 2000, Mr. Rosas discovered National Karate and was impressed by the quality of students produced and the amazing family like atmosphere. Soon he had his whole family join! His daughter Claire is now a 2nd Degree Black Belt and his other daughter Annie is a 1st Degree Black Belt. Mr. Rosas says he “just loves the students and staff that he gets to work with.” He is now a 4th degree Black Belt and is a Krav Maga Certified Instructor.
