Olivia fell in love with hapkido for its applicability, size-independence, and diversity. She stumbled onto hapkido while looking for a self-defense-oriented art that would strengthen her physically and mentally. Over a dozen years later, she has continued practicing hapkido because it has endless facets to explore at all ranks, has allowed her to empower others by teaching self-defense skills, and introduced her to some of the most inspiring people she knows.

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.
Michael started training Hapkido as an undergrad in 2009 as an engineering student. He finds the simple but effective mechanics of the art to be fascinating, and enjoys the great workouts and good people.
Instructor/Office 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. With a background in orthopaedic biomechanics, he found the joint locks, throws, and grappling very interesting and fun. 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.
