Aloha from Hawaii. Mr. Yankello, I teach high level martial arts and am now incorporating your philosophy into my training…I feel like it has elevated my teaching and made my students extremely more effective particularly in the forum of hand to hand combat in urban environments: I have been around urban combat all of my life with several very well known trainers and you sir, are one of the very best I have seen and learned from in any discipline. I hope to meet you very soon and your doing amazing work. GrandMaster 9th Degree Kajukenbo Dan Barretto
