I am the the owner of ORTHDX Natural Fitness in Madison Wisconsin USA. I've been a practitioner of Southern Praying Mantis for over 20 years. I've published 3 introductory training videos and one book on the Chuka family of Southern Praying Mantis. (The first family I trained with.) I have also published numerous materials on Rattan Ring training and how to adapt it other styles of martial arts. For the past several years I've studied Chow Gar Southern Praying Mantis under Sifu Steve Tansley and am currently Master Paul Whitrod's Chow Gar representative in the United States.
