With Over 30 Years Experience, Seishin Creates Champions In Martial Arts And Life.

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 students of all ages and ability levels. Our goal is to not only create outstanding martial arts athletes, but to also use our sport to guide our students to become outstanding people. Over the years, Seishin has produced over twenty state champions, fifteen national champions, and five world champions. Our regional competition team, “Team Seishin,”  is consistently ranked as one of the best in New England.  Seishin members and instructors have been featured in movies, documentaries, music videos, and on ESPN. 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. Our students develop relationships and life skills that will last them a life time and use the martial arts as a guide to becoming better people. We thank you for your interest in our academy, and welcome you to experience what sets Seishin apart from the rest.
