When I came to Rosendo Diaz’s Brazilian Jiu jitsu academy, I was a former wrestler looking for an activity to keep me fit.  I wanted an activity that was safe, fun, and challenging. Not only did Rosendo Diaz Brazilian jiu jitsu meet these expectations, but also exceeded them. While training with Rosendo, I have lost close to 30 pounds, tremendously improved my flexibility, and, most importantly, learned to defend myself.  Many times people get into BJJ thinking about MMA or for sport, in either case; Rosendo begins with a solid foundation of self-defense and builds up. Whether your interest is in MMA or submission grappling, Rosendo will provide you a solid foundation that translates into all aspects of BJJ: self-defense, sports grappling, or MMA. I have trained in Brazil, with BJJ world champions, and with UFC veterans, in every case, having trained under the precise instruction of Rosendo gave me an advantage. 


Still, I do not want to give the impression that Rosendo Diaz’s Brazilian Jiu jitsu academy is only for serious training and fighters. The school’s environment is friendly and welcoming. The friendship and camaraderie resembles a large extended family more than a traditional martial arts school.


I recommend to everyone, come and train with Rosendo and you will not regret it!

“I started training Brazilian Jiu Jitsu in June of 2003, under the instruction of Rosendo Diaz (1st degree Royler Gracie/David Adiv RGDA certified black belt) in Telford, Pennsylvania.
At the time I started training I was overweight and my physical condition was very poor.  I had tried all kinds of diets, training programs and supplements to help resolve my weight problem but nothing worked.  After doing some extensive research, I decided to try Brazilian Jiu Jitsu since it involved group activity and would teach me self defense in the process.
Under the tutelage of Rosendo Diaz I was able to improve my physique, lose weight and make a lot of friends along the way!  I have lost a total of 87lbs and now I feel great!
If you live in the lehigh valley area, and you are trying to improve your physique, learn self defense, become a world class Jiu Jitsu player or just make some friends and have fun.  I highly recommend training at Gracie PA, under Rosendo Diaz.”
