The Rosendo Diaz Brazilian Jiu-Jitsu Academy opened its doors in 1996 and never looked back. Over the years we have trained and taught men, women and children how to defend and feel confident about themselves.  We’ve taught law enforcement officers the most up to date defensive tactics. We’ve helped our students become champions both on and off the mat.  But most importantly, we’ve carried the flag and helped spread the word for the most effective martial arts in the world, Gracie Jiu-Jitsu.


This 20th year we are celebrating by offering you 3 months of unlimited training in Gracie Jiu-Jitsu for only $149.00, we’ll also throw in a pretty cool t-shirt.


Come on in, try out a class, kick the tires so to speak.  Visit us on Facebook , meet our members there and hear their stories plus you can view videos of us doing our thing.  Call us if you have any questions or would like to set up a visit 610.850.1604

Heard about Jiu-Jitsu but you don’t know the first thing about it?  Maybe you don’t think it’s for you?  Guess again!  Take a look at this exciting and informative documentary that helps explain what Jiu-Jitsu is and helps dispel many of the myths associated with Brazilian Jiu-Jitsu.  Remember, you don’t have to be a fighter in the UFC to learn BJJ.  Gracie Jiu-Jitsu was developed for regular people to help them be prepared to defend themselves.


After watching the documentary, give us a call and get started on a new path towards a healthier lifestyle.  267-476-1858.



Success Takes Time

We talk a lot in the Jiu-Jitsu community about the health benefits training in BJJ provides but what happens is we get so focused on the actual training and the lifestyle that we don’t see the effects Jiu-Jitsu has on the body. Then 5 or 6 years later someone reminds you of what you looked like when you first started….


Dan Katz started at our academy back in April of 2010. The photo of Dan doing the Captain Morgan was taken 2 months prior to starting at our academy. He weighed 220lbs. The other photo is much more recent but Danny has been in excellent shape for several years now, he averages around 150lbs.


That’s what is so great about BJJ, it’s about truth on the mat. At 220lbs Danny couldn’t move on the ground, he would get tired and winded fast. Jiu-Jitsu brings out a truth that the latest work out craze or the treadmill that now doubles as a clothing rack doesn’t.  The truth is if you are getting on that treadmill or that workout video a couple times a week or as time allows, you’re really not making a change.  You’re what I call “maintaining a feeling of a healthy lifestyle”.  Yes you are doing well for the health of your heart, but you’re not making a substantial change to yourself.


Whether Dan knew it or not, he embraced the BJJ lifestyle.  He looked at himself and realized he needed to eat a healthier diet, he needed to improve his cardio, he needed to strengthen his muscles, and he needed to improve his flexibility.  Of course these things didn’t happen overnight, they happened slowly as a result of the truth he was experiencing on the mat during training.


Today, Dan is a purple belt in Jiu-Jitsu, has done extremely well in competition and is an instructor of our beginners program.


You don’t need to be in good shape to start Jiu-Jitsu, you just have to want to make a change.  Find your own truth and embrace a healthy lifestyle not because someone told you on TV that in 30 days you would be a new you…The reality is that change takes time, but more importantly it takes motivation. “If you have a passion for a thing, then that thing gives you all the motivation you need” That’s the truth of Jiu-Jitsu.

Call or stop in today, take 2 weeks free to try out our classes and meet our members.

Jiu-Jitsu isn’t just about learning to defend yourself.  It’s about fitness, it’s about a healthy lifestyle, it’s about developing friendship, it’s about being part of a global family, it’s about being part of a team, it’s about changing your life, it’s about who you are and who you want to be.

Sheri Hockman started her journey in 2002.  Jiu-Jitsu requires an incredible commitment to achieve black belt, added to that the fact that currently it is a male dominated sport.  It is with that in mind that we celebrate with Sheri and congratulate her on this amazing accomplishment.  Sheri was promoted by Rosendo Diaz on August 22 at the annual 3rd Generation Jiu-Jitsu Team promotion Ceremony.
