Head Teen Instructor/3rd Dan
Dr. Matthieu Bloch
​Dr. Matthieu Bloch started martial arts during grad school when looking for an engaging way to exercise. He chose Hapkido because of the versatility of the art, the emphasis on self defense, the friendly atmosphere that fostered personal growth, and because mastering nunchucks and joint locks looked just awesome. Years after, he finds learning and teaching Hapkido just as exciting and rewarding.

Instructor/Manager/2nd Dan
Dr. Victor Ellingsen
Victor started training in Hapkido in 2013 as a way to get in shape and manage stress, and quickly came to appreciate the flexible and practical nature of the art as well as the sense of community at Black Knight. After earning his first degree black belt he moved out of state for several years, during which he tried other arts but Hapkido and Black Knight always felt like home. He’s happy to be back in Atlanta teaching and learning alongside some of the instructors who taught him, and especially enjoys working with students who might be hesitant to try martial arts due to size, age, differences in ability, or any other reason.

Dr. David Safranski
Dave Safranski started hapkido at Black Knight in 2017 because he wanted a physical and mental challenge.

Over the years of training, he continues to find joy in learning the small details of the self-defense techniques and when he overcomes mental hurdles.
