This school offers great instruction at a very reasonable price. I trained in Muay Thai and Gracie Jiu-Jitsu here for the last year, and have been very happy with the quality of instruction and the atmosphere, which has always been friendly without sacrificing dedication and focus in training. The other students are also dedicated and enthusiastic martial artists and they help make the school what it is. I've trained at two other Philadelphia Muay Thai gyms, and the area is fortunate to have several top-notch training facilities and some really skilled instructors. I count Joe Diamond among them. After one year of training with him I was able to hold my own against much larger opponents. I am about 150lbs, and was able to take the back of a security guard easily 100lbs heavier than I and submit via rear naked choke. Thanks to the training I've received, I think about whether a match is fair based on experience rather than size, and I think that's the essence of solid martial arts training.
