I was Training at Yamasaki at the time and went to the free sessions and open mat at standard. I was struggling with mental health issues at the time and Greg and Noah and the rest of the crew were as patient as anyone could be. This gym is an Extremely skillful gym. I've spoken to Greg multiple times about jitsu in general and I have not spoken to anyone nor listened to any YouTube video with that level of intellect about the sport. Thanks for being patient with me, and the time invested in me as I never paid Greg a dollar between the 7 free sessions they offer and open mat, but I learned priceless knowledge. Hearing Greg tell the story about how a prince of Saudi along with the Gracies started the ADCC was awesome. Thank you all, and sorry for any misunderstandings while I struggled with mental health issues at the time! God bless. OSS.

The shifus who run this school are extraordinarily knowledgeable about martial arts and their instruction is of the highest caliber. They are examples of excellence and do much credit to the memory and legacy of Master Dunphy, the school itself, and the study of the internal and external systems of tien shan pai. (For clarification, my initial review of the school contained a reference to USCKF, the United States Chinese Kuoshu Federation, which is now known as USKSF, the United States Kuo Shu Federation.)

The head instructor took special attention to individuals and trained them in a way that fostered positive growth. There was always a focus on effective self-defense and very little of the "dance" moves that make other martial arts training less effective. The style taught here is Thai-Shan-Pai and from my experience, it is highly effective for anyone to use against an aggressor. I couldn't recommend this school enough and we still be going here if I lived in MD. If your looking for solid training, regardless of age, sex, or size this is the place.
