Randy Rubinfeld

Meet Sensei, Randy Rubinfeld; a 4th degree Black Belt, 3 X Sport Karate World Champion and 2 X Hall of Fame winner.


Sensei Randy began his Martial Arts journey at the young age of 3 years old. His journey started under the leadership and instruction of Sensei Jason Frank (known for his role as the Green and White Power Ranger). It was right after Sensei Randy's very first competition at the tender age of 4 years old, when he knew that Martial Arts would be a big part of his life and from there as the saying goes..the rest was history! 


He went on to be under the leadership of Shi-han Chris Casamasa (known for his role as Scorpion in the film Mortal Combat and George Clooney's stunt double in the film Batman and Robin). It was during this time that Sensei Randy broke all records for winning 14 straight Grand Champions titles in a row. Sensei Randy then blossomed into a 1st degree Black Belt under the instruction of  Shi-han Mohammed Jahanvash. It was under the leadership of Shi-han Mohammed Jahanvash that Sensei Randy discovered his love and passion for teaching Martial Arts. 


In 1996, at the age of 11 years old; Sensei Randy was scouted and picked to become a part of an International Sport Karate team sponsored by the legendary fashion designer, Karl Kani. It was during this time that Sensei Randy traveled the world, competed in hundreds of Nationals Tournaments and earned 3 NBL World Titles. In 1998 Sensei Randy was part of the best Sport Karate Team in the world and the timing was perfect for Sensei Randy's father, Craig Rubinfeld, to open the original World Champions Martial Arts Center in West Covina, California. WCMAC became the headquarters and training center for Team Kani, the best Sport Karate Team in World. During this time, Sensei Randy was under the instruction of World Renound Champions Butch Togisala, Omar Guerrero and Jason Tankson Bourelly. At the age of 14, Sensei Randy took over the school as head instructor and worked hard to take WCMAC to be #7 in the World and #3 in California by the National Black Belt League (NBL). 


When Sensei Randy turned 18, he decided that he wanted to take a break from full-time Martial Arts to pursue his other passions in fashion and music and decided to close the Karate school. During this time Sensei Randy was teaching Martial Arts part-time at local daycares and schools, consulting and conducting seminars to fund his fashion and music career. He then went on to achieve many accomplishments; such as working with the YouTube Network. After a few years, Sensei Randy realized that his calling was in Martial Arts as he began to miss the teaching aspect of it. He decided to devote his life to Martial Arts and re-opened his school World Champions Martial Arts in Mission Viejo, California.

Chi-Do Tae Kwon means The "Energy & Art of Foot and Hand fighting", but it's more than that. It is the scientific use of the body in methods of self-defense. Chi Do Tae Kwon creates a mind and body that has gained the ultimate use of its facilities through intensive physical and mental training. It's a Martial Art that has no equal in either power or technique. It is a very fast and powerful martial arts form that requires each student's desire, effort and getting commitment to excel.
