MMA Classes at the PSDTC

News: PSDTC Warrior, MMA Scholarship Program.

Our Mixed Martial Arts, AKA - MMA (meaning, Mixed Martial Arts) classes are a blend of Jeet Kune Do blended with Muay Thai and Brazilian Jiu Jitsu, Russian Sombo, Judo, Catch Wrestling (AKA, Catch-As-Catch-Can), Shooto (Japanese Shoot Wrestling), Dumog and Silat. These Grappling styles we blend are referred to at the PSDTC as IGS, or Integrated Grappling Systems.

We train and condition hard at these classes. All fighters over the years who have participated in Muay Thai and Grappling tournaments and MMA matches have always done well. If you are the type that would like to be in these types of tournaments and eventually go pro, well you are coming to the right place.

If you are not interested in the tournament lifestyle, that is ok also. You can still get the great training to get into very good physical condition and gain self defense skills that will work well for you in the ring or the street. There are always opportunities to spar with the ones who do want to be fighters as well as those who do not want to be tournament fighters.

Guaranteed, in one month you will see big results from this class.

We are looking for people who do want to fight, female or male. We have many connections all over the US to get you fights. We can get you a fight a month if you want to. If you become good enough, we can get you pro fights where good money can be made.
