William Kim’s

Taekwondo in Vallejo, CA

We've been helping our students achieve better lives for over 40 years. Not only have we helped produce numerous national and international champions, but more importantly, we've helped develop thousands of safer, stronger, more focused men, women, and children. In a world of changing values, we believe some things are enduring. Some truths are eternal. People live better lives when they have self-discipline to reach their goals and confidence. Families bond and excel when boundaries, goals, and achievements are expected and respected. And expert, experienced guidance is priceless. Tae Kwon Do is a powerful, time-tested path to these ends. That's exactly what we offer. We'd love for you to join our community today.

Meet Grandmaster

William Kim

Owner at William Kim’s Taekwondo in Vallejo, CA 9th Degree Black Belt

Grandmaster William Kim is both a National and World Tae Kwon Do Champion, and is a two-time inductee into the United States Taekwondo Hall of Fame. He recently traveled to Kukkiwon, Korea to test for his 9th degree black belt. He joins the ranks of less than 100 Kukkiwon Certified 9th degrees in the entire USA. It is the highest achievable Taekwondo rank.

A native of South Korea, Grandmaster Kim began Tae Kwon Do at the age of six, studying under his greatest mentor and life-long influence - his father, Grandmaster Hae Yong Kim (9th Degree).

After spending eight years in Hawaii, Grandmaster Kim moved to California in 1980, and firmly established himself as one of the few who can genuinely be identified as one of the top Martial Arts Masters in the world.

His reputation is truly global.In addition to his Hall of Fame inductions, Grandmaster Kim serves as Chair of the Vallejo-Jincheon Sister City Committee, and was awarded the Presidential Champions' Award by Bill Clinton, among many other honors and activities.

Grandmaster Kim's core philosophy and approach to Tae Kwon Do is strongly focused on developing the "whole person", not only developing physical strength and agility in his students, but also strong values, focus, and integrity.

Tae Kwon Do is far, far more than fighting - it's a way of life that instills many of the best aspects of what it means to be a good citizen and neighbor.
