Owner, Sensei Robert Koncal

founded Kachi Karate in 1999. He is the Chief Instructor of the Kachi Karate schools and has over 25 years of experience. Sensei Koncal started practicing karate at the age of seven and after a few years of training he was chosen to compete in an Inter-Dojo kumite competition. He won all his matches and became the champion which sparked an interest into his competitive career. Since that moment he continued to train rigorously which resulted in capturing numerous titles and becoming multiple National Kumite and Kata Champion.

At the age of 16, he represented his home country of Slovakia at the World Karate Federation (WKF) - World Karate Cup and earned a silver medal in kata (forms). During the six years of being a Slovakian National Team Member, he placed 4th in the World and European Championships. In 2002, he was invited and had the opportunity to compete in the AAU/USA & USANKF National Championships where he received a gold and silver respectively.

After an injury which ended his sports career at a young age of 22, he directed his love and passion of karate and competitions to coaching. With his newly established Kachi dojo, he was able to guide many of his students to National and International Championship titles. With the exceptional results of his students, his high quality and professionalism of teaching, and years of experience and knowledge, he was asked to become a National Coach for the Slovak Junior and Senior Teams. Coming on board with the coaching staff, his expertise helped the national team to earn a WKF World Championship title, WKF European Championship titles and many other results in prestigious competitions. In 2006~2008, he had the honor in being named the “Most Successful Coach” for his dojo being ranked #1, and also awarded “Coach of the Year.” In 2010 he relocated to Hawaii to expand his Kachi dojo and spread his love of karate to the people of Hawaii.
