Grandmaster Y.K. Kim?s whirlwind life has taken him from Korea to the United States while wearing many hats including author, public speaker, philosopher, entrepreneur, and founder of Martial Arts World. The latter has grown into a family tree of locations spanning four states. At each location, dedicated instructors guide kids and adults through martial-arts classes that aim to instill a sense of confidence, self-discipline, and respect in each and every student. Classes serve as sweat-inducing workouts and an outlet to learn self-defense techniques, which come in handy when you dream your blanket has attacked.
