What Is Seishin?

Since opening it’s doors in 2000, Seishin Martial Arts / Sport Karate Academy has been the leading martial arts school in the Greater Boston area. We offer martial arts and fitness classes for both children and adults of all ability levels . Our goal is to not only create outstanding martial arts athletes, but to also use our sport to guide our students to improve their lives and become outstanding people. Over the years, Seishin has produced  28 state champions, 30 national champions, and 11 world champions. Our regional competition team, “Team Seishin,” is consistently ranked as one of the best in New England and Seishin maintains a close relationship with Team Straight Up, one of the best sport karate teams in the world. Seishin instructors have been featured on/in ESPN, movies, documentaries, music videos, as well as the WKC USA World Team. But the greatest success for Seishin occurs off the mat, as Seishin not only creates champions in the martial arts, but also champions in life. Students are taught the importance of effort, etiquette, character, sincerity, and self-control all while developing relationships and life skills that will last them a life time. We thank you for your interest in our academy, and welcome you to experience what sets Seishin apart from the rest.
