I have been training with Mr. Rainey for almost 2.5 years, beginning at the end of March 2013. I believe this will lend some credibility to this review.
Mr. Rainey knows his art, and has direct lineage back to the founder of the American Kenpo system, SGM Ed Parker.
Mr. Rainey is very much attuned to how to teach, encourage, and develop the skills of beginning students, just as he is for the advanced. This is regardless of whether the student comes to American Kenpo from another system (as in my case) or is completely new to the martial arts.
It is worth clarifying that Mr. Rainey teaches is a "martial art" not a "sport". There is a big difference between the two and there are not so many schools that do this anymore. If one's interest is to learn effective self defense, this is the place. With that being said, American Kenpo is also a very complete/comprehensive martial art system that transcends just personal self defense. It is also about self discipline, personal growth, the development of greater self confidence, and physical health.
After devoting over 40 years to the martial arts myself, most notably training and teaching Taekwon-do (before choosing to start all over again with Mr. Rainey and the American Kenpo system), I can certainly attest to Mr. Rainey teaching abilities and the overall effectiveness of the American Kenpo system of martial arts. My only regret has been that I did not come to know the Kenpo system, and Mr. Rainey, 42 years ago when my own martial arts journey began.
