Wonjin Hapkido is “simple and effective self-defense” it’s 90% effective 90% of the time against 90% of attackers.

Roy really helped me improve my American English accent, I’ve been wondering “what’s up” for years, nobody could explain it, Roy made it super simple, it basically means: how are you, what’s new, how’s life, what’s wrong… that phrase always confused me so much. He was able to clarify a lot of slang, I really appreciate him and his professionalism. Thanks Roy!
