As a competitor, he was Pan American champion, sub champion in Combat and Kata in the United States, multiple times champion and light sub champion in Costa Rica and was inside the best 16 light fighters of Japan in 2010.

Sensei remains in constant technical learning. He visits his teacher annually in Japan and participates in Karate camps and seminars around the world.

With Sensei, karatekas from different countries in Latin America are prepared, trained and certified annually, a region in which he also gives seminars on a regular basis.

In addition to his martial training, Sensei has high-quality functional and CPR training certifications from the American Heart Association.
