Sensei DeValentino is an amazing teacher in Okinawa Kenpo. I enjoyed learning from him when we were both in Hawaii back in 2011-2012 and still continue to train even though I am in California. Learning from Sensei also helped me to be a better leader when I was in the Marines. I look forward to earning my Second degree black belt soon. Senpai Kevyn

DSSI is the best karate organization. It has a lifelong mission to train and inspire kenpo karate style katas, weapons and self defense techniques.

It is the consummate karate family training environment!

I've known Marcus for many years his skills are only matched by his experience. I have no doubt any job or task at hand he could accomplish.

Marcus and I worked side by side together in many multimedia productions. He is always very professional, prepared, and organized when it came to his responsibility pertaining to the project.

I have trained with Sensei Marcus for 4 years now and I can say that I would not get the level care and attention from anyone else. He is the very best around San Antonio.
