In 1998 he started studying American Kenpo Karate, eventually earning the rank of 2nd degree black belt under Josh Ryer. In the years since he has trained in Filipino Martial Arts and Japanese Jiu Jitsu before beginning Brazilian Jiu Jitsu in Lancaster, PA. After moving to the Philly area he continued training in BJJ and Judo. Jason has been teaching martial arts and self defense since 1999 and has offered classes and private lessons to the Mainline area since 2015. He continues his Jiu Jitsu training under Professor Daniel Gracie and his Judo training under Sensei Tom Blair. Coach Jason and the DGM team are very active in local competitions. He believes in challenging himself to be the best for his students, determined to always offer the most effective self defense and sport Jiu Jitsu concepts and techniques. 

Make a Change

Real People.

Real Results.


Starting BJJ at Daniel Gracie Mainline has been the most positive transformative action I have taken since I wandered into those middle years of my life. There is no way to express to you how my lifestyle has changed since signing on with Coach Jason Santiago.  The confidence I had as a younger man has returned and I just feel better about who I am. With BJJ not only do you learn a form of self-defense, but you become physically and mentally fit. You find yourself being part of something bigger, being part of a team. A team where you develop relationships that stretch far beyond the edges of the mat, a second family that celebrates each other’s achievements and is also there to comfort each other when need be. I urge you all to try a free class, meet some of the people, and start making that positive change you are looking for.


About two years ago my journey led me to Daniel Gracie Mainline, and I can confidently say that this academy has exceeded all my expectations. From the moment I walked through the doors, I felt a sense of camaraderie and dedication that truly sets this place apart.

Coach Jason has created a positive and welcoming atmosphere that fosters growth and learning. Whether you are a beginner or an experienced practitioner, everyone is treated with respect, creating a supportive community that encourages each student to reach their full potential.


My children have been going here for several months now. They have learned so much. We see them more confident, and stronger. Coach Jason also works on respect, being a team player, and on supporting each other. We love coach KC, Mike and all the other coaches.



Owner Jason has tailored applicable lessons for me and my friend. As young women we feel far more confident and prepared for an otherwise stressful scenario. Jason couples exciting repetitions with corresponding explanations of how different maneuvers help diffuse violence.
