Why should you

start training today?


Our programs are designed to give you a high intensity training that lowers your cholesterol levels and increases your cardio.

This lowers your chances of developing dangerous diseases and keeps your body strong!


Knowing that you can defend yourself and your loved ones is reason enough to start training.

Did you know that your training can also dramatically reduce stress and anxieties?


When your head is in a lock, you won’t get out by doing the same things over and over.

It requires new-thinking and that you keep your mind clear.

These skills will help you both on the mat and in your daily life.


While going to the gym is a great way to workout, it can be quite boring.

Our training is a fun all-around body workout, so you barely notice working out, and still get all the benefits.

You’ll see your body transform to how you want it to be very quickly!


The discipline you build in the academy is not only useful in training and competition.

You will start seeing great improvements over all in your life at work, at home and in yourself.


When you join us you become a part of social circle that can best be described as a “second family”.

You will begin noticing and understanding how your opponent thinks and moves, which is also helpful in social situations.

“I take many of the lessons and values he has tought me into life with me.”

Chris Reyman is a knowledgeable, patient and efficient instructor that I have had the pleasure to work with for many years during my jiu jitsu career. His love for the sport has helped inspire me to pursue jiu jitsu as a career myself. Even though Chris and I no longer extensively work together I take many of the lessons and values he has tought me into life with me today. Chris is an overall wonderful instructor and taking his classes will only do you good.

Professor Carl Massaro

“If you’re looking for a qualified, knowledgeable instructor, look no further.”

Professor Chris Reyman is a phenomenal instructor and practitioner. He has been studying the Jiu jitsu/grappling game for well over a decade under Renzo and John Danaher and continues to teach and train daily. Chris is a phenomenal black belt and has been a great training partner for me over the years. As a fellow black belt instructor, I am impressed by Chris’s knowledge, dedication and continued study of the art. He has trained with some the best in the world and due to his continued study of the game, he has a vast understanding of modern, cutting-edge techniques. He has an amazing understanding of wrestling and mma as well as gi and no-gi bjj. If you’re looking for a qualified, knowledgeable instructor, look no further.

Do you also teach children?

Yes, we have kids classes available from 2 years old.

Do I need to buy anything?

You are not required to purchase anything in order to participate.

We have Kimonos for rent $10 daily fee to cover cleaning cost.

We recommend buying some basic gear like a Kimono, belt, mouth piece, rash guard and shorts as well as a groin cup for continued daily training.

Is it dangerous?

We limit the liability of injury in our training methods by implementing a systematic approach to learning & development for all members who are beginners.

We adhere to IBJJF complaint rules and regulations so that the development process is smooth and safe for all participants at each level.

Comprehension of technique and form is drilled and focused upon over Randori (live sparring, aka rolling) and the ratio of the two should be in a proper balance at the discretion of the class Sensei.

How often should I train?

The answer to this question often baffles people because the truth is you should Always be training.

How is this possible?  Well let me tell you that it’s all about mind set and mental skills. Do not just see this as a physical activity because Jiu-jitsu like any other martial art is a system of thought and expression.

 Generally I advise people to start physical preparation at least 2-3 times weekly but that doesn’t mean you cannot watch and observe all the while learning more than actually participating.

Trust me when I say you need to do both and your development will always progress.

Learn to train your mind and body in balance. 

Always be training.

Do you offer private lessons?

Yes the rate for one private lesson is $150 per hour.

Do you have a drop in fee?

Yes, if you are a non-member it is $30 per class.
