Welcome to Ko's Martial Arts Academy

Ko's Martial Arts Academy, established in 1976 in Columbus, Indiana, by Grand Master Yun Sam Ko, is the leading martial arts school in Columbus, Greenwood, and Seymour, Indiana.  Under the ongoing instruction and guidance of Grand Master Ko, Ko's teaches taekwondo and the physical, mental and spiritual aspects of the art to students of all ages.  Come in and check us out!

At my first few lessons, my complete lack of grace or natural ability was apparent, but no one at Ko’s said anything negative. On the contrary, this is the most positive environment I have ever been in! Everyone welcomed me and has helped me learn, encouraging me along the way. I never dreamed that I would like it, let alone LOVE it!
