Query: Awesome techniques and well defined master keys

I was actually a student of Dr. LaTourette's for several years when I lived in Medford OR. Contrary to the diatribe of the previous reviewer, Docs methodology is solid. In my personal experience, Doc has always gone out of his way to present effective, efficient and devastating techniques. Additionally, Doc clearly defines the master keys (i.e. gravitational marriage, closing gaps and nerve cavities to name a few) behind the various techniques. Good luck in your martial arts practice.
