JPMAA has been open and operating at its current location since December 2012. Formerly known as Mass Bay Brazilian Jiu Jitsu Academy, our program has expanded which necessitated the name change. The academy was opened by Dr. David Shim who has been training in martial arts since 1972. Martial arts is a wonderful and enjoyable form of physical self defense training which has significant impact on one’s physical and psychological health.

At JPMAA, we provide a family friendly atmosphere where everyone is welcome to come and train and have a great time. We provide structured training programs for adults, children, and families. We offer programs in Karate and Brazilian Jiu Jitsu. Our instructors have decades of experience and the emphasis is on enjoying working with each other and attaining positive results both physically, mentally, and spiritually. Our head instructor, Dr. David Shim, is a clinical psychologist whose dissertation topic was on the psychological benefits of self defense training.

We offer separate programs for Karate and Brazilian Jiu-Jitsu and our Black Belt instructors are very competent and caring in their teaching approach. We offer student-centered instruction which aims to help you reach your physical and self defense goals. Our Karate program has a lineage which can be traced back to pioneers of Karate such as Gogen Yamaguchi, Peter Urban, Richard Kim, and Joseph Hess. The Brazilian Jiu-Jitsu taught at JPMAA has its heritage in the traditions of the Gracie family who developed the art. Our head instructor trained under Professor Roberto Maia of Boston Brazilian Jiu Jitsu who is first cousin to Renzo Gracie. Our programs are technical, proficient, and rigorous yet maintains an emphasis on enjoyment and health.
