Class Info

We operate as an informal club, with our mat time and space rented from Davis Square Martial Arts.  If you arrive early to class, there may be a Tai Chi or Kung Fu class still in progress.  You may wait in the upstairs lobby until Jiu-jitsu members arrive.

Class Schedule:

Classes are held Tuesday and Thursday evenings, 8-9:30 p.m.


Monthly club dues are $80.  There is no per class rate, however, for new students, the first class is free.  You are welcome to attend as many classes per month as desired.


Jiu-jitsu is a close range grappling method of unarmed self-defense that focuses on using superior positioning, leverage and strategy to defeat the opponent. Through the proper use of Jiu-jitsu techniques and strategy a smaller person can defeat a larger person and often without giving the larger person any serious injury. As students get more proficient they will learn and practice unarmed defenses vs. attackers that are armed with guns, knives and bludgeons.

Class starts out with a light personal warm up then the students practice two person drills that mimic various attacks and counter attacks. Then new techniques and strategies will be taught and practiced. In the last 10-15 minutes of the class all but the beginner students will take part in rolling, which is a safe form of sparring in which the students will strategically battle to get the other student into a finishing hold while preventing the same from happening to themselves.


Students wear belts in colors signifying their rank.  Each belt signifies the acquisition and confident use of certain techniques and skills.  Students are informed when the next belt exam is coming up as they master the techniques through practice and dedication. This exam tests the student by requiring her/him to successfully defend her-/himself in various dynamic scenarios.

  • The belt hierarchy, in order of beginner to advanced for Jiu-jitsu:  white, green, blue, purple, brown, black
  • In between each color belt, a stripe is awarded as a mid-point indicator to the next level

While a student’s belt promotions are strongly related to the time spent practicing, if a student excels exceptionally in the mastery of the various techniques, belt promotions may be accelerated in accordance with the student’s progress.

Safety and Culture:

Mike Perry’s Boston Martial Arts Institute operates on the principle of safety first. Students are instructed on how to prevent and minimize injury to themselves and others. Within this premise, the dojo is dedicated to working with students’ individual needs and limits. We welcome students over the age of 16 from all backgrounds and walks of life. While all students will learn all techniques in each discipline in accordance with their belt rank, we strive to personalize the emphasis of specific techniques based on each individual’s strengths and weaknesses.

Students are expected to wear clean gis and belts during training and to treat all dojo members with respect and courtesy. Students are also expected to disclose any minor injuries or physical discomforts that don’t prevent them from participating completely. This policy ensures consideration and cooperation in avoiding further injury during drills, sparring and rolling/grappling. In a similar vein, we do ask students with the flu or other close-contact transmittable diseases to please skip practice until they are no longer contagious.

Mike Perry’s Boston Martial Arts Institute seeks to create a welcoming atmosphere for all and does not discriminate on the basis of race, color, sex, gender identity, sexual orientation, nationality, ancestry, religion, disability, genetic information, veteran status, or national or ethnic origin.
