From that day on, Kru Ronão has trained in many different styles including: Karate, Judo, Capoeira, Boxing, Kung-fu and Kickboxing. But it was the martial arts forms of MUAY-THAI, JIU-JITSU and KALI where Kru found his true passion. In 1995, Kru began training police and army personnel, along with the general population ranging from kids to professional athletes. With a bachelors degree in physical education he combines the scientific with the rough aspect of fighting in an ultimate way. Kru Ronão trained with the biggest names of the three styles in Brazil, Holland, Thailand and Philippines. He moved to the United States a couple of years ago establishing himself as a top trainer and fighter, helping many great names in MMA (UFC, WEC and Cage Rage) like Gabriel Gonzaga, Thiago Silva, Hermes Franca, Jorge Rivera, Paulo Filho, Gabriel Gladiator to name a few. As a teacher, he is dedicated and passionate about helping his students and fighters accomplish their competition, fitness, self-defense and well-being goals. They say walk softly and carry a big stick and that applies to him– though he walks softly and carries a big smile. The Lion’s Den is really fortunate to have him here.
