About Us
Mary Johannesen opened Keller ATA in August, 2007 after beginning her taekwondo journey in New Jersey with her daughter. A Navy veteran and single mom, it was her desire to create a family friendly school where all would be welcome and included.
Nathan and Mary met in 2018. He had always wanted to take a martial arts class, as Chuck Norris and Bruce Lee were childhood idols. Nathan began taking classes and found a passion for teaching and working with kids. Tying the knot in 2019, Nathan and Mary have been teaching together ever since. |
Families at Keller ATA appreciate the solid team Mary and Nathan make and the love they have for Songahm Taekwondo, teaching and inclusivity.

"We absolutely love Keller ATA. We started here because my daughter was being bullied by a boy at her school and I wanted her to learn how defend herself and get out of bad situations. Mrs. Mary has been a life changer for our family. Both my kids and myself are now students. My daughter just recieved her black belt and I'm next. My son has a ways to go, but hes very excited about the belts he's earning. Keller ATA is family!"
