I've met and trained under a number of "3-star" martial arts teachers, and even a couple of 4-stars. But I have no hesitation at all in giving Master Jeffrey a well-deserved 5. I could write a page about why I like training with him, but foremost of all, IMHO, is his dedication to the fundamentals, and his truly amazing ability to point them out during training. I've been "around the dojo," as it were, for over 40 years, and if I've learned anything, it's that true mastery lies in the fundamentals. Master Cook constantly pauses in training to illustrate how the fundamentals emerge in each scenario: "Look - there's movement number 1," "There's the little step from the bow," "That's the cross-body block from the first form," and on and on. Anyone can teach anyone else the basic movements of a form, a bow or what-have-you. But only a true master can show you how the fundamentals are woven together to achieve everything else. I am so grateful to the Tao for introducing me to Master Cook. If you *really* want to "live to train, train to live," you MUST study under this man.
