James Conkell, who is the head instructor of Alpha Combatives, is great, patient, and extremely knowledgeable. He is very conscientious and caters his classes to suit the interests, experience/skill level, and needs of the individual. For me, this has included exposure to JKD, Muay Thai, boxing, karate, and Escrima. I am also really interested in learning how to react in situations where I might have to defend myself, so I also appreciate getting the chance to learn techniques that are also on the more practical side. This is a mobile business, so while it says he is based in Arlington, he has come out to teach me in DC. I look forward to every class and always feel like I am getting a great work out as well as improving my technique. His prices are also very reasonable and I highly recommend contacting him for more info.
