Master Cook is credited with the creation of the Chosun Women's Self-Defense Course. He has also provided training for the US Army National Guard/42nd Division prior to military operations and has instructed agents from the Department of Homeland Security, the New York Police Department and the Bronx County Sheriff's Department. Master Cook was called upon to demonstrate taekwondo as part of a three-man team at the annual Oriental World of Self-Defense held in New York City's famed Madison Square Garden. There, he and the team were cheered on by martial arts legends such as Richard Chun, Henry Cho and Chuck Norris.

Because he is a traditionalist, Master Cook places great emphasis on the underlying philosophical principles and self-defense strategies surrounding taekwondo. He demonstrates this belief by infusing meditation, breathing exercises, a strong attention to basics, and the practice of the classical forms, or poomsae, in his instructional methodology.

Master Doug Cook currently shares his knowledge of taekwondo through a series of articles he has written for Tae Kwon Do Times, Black Belt, Totally TaeKwonDo and the United States Taekwondo Association Journal, as well as various other martial arts publications. For the past twelve years he has written a monthly column for TaeKwonDo Times called Traditions.
