  • The staff is absolutely amazing. My kids are 3 and 5 and in the same class together. My younger one has really had a hard time adjusting to taking the class. They have been so patient with him and talked to me on the phone on off hours and listened to me cry about my parental struggles.Last week my youngest got his first stripe and I think he's excited for the next class! Many struggles to go, but I am so thankful for the time East Montgomery Martial Arts has taken with my children...they say it takes a village.

    I’m 37, and have been in Mr. Exaros’ Brazilian Jiu Jitsu class for more than one year. Mr. Exaros provides the perfect amount of detailed instruction each class, and then opens the mats to free roll to apply what was learned. The members here roll in a controlled, respectful manner, and gauge the level of intensity that is appropriate for you. I leave feeling great from an excellent workout. I have gained an incredible amount of respect for people who study the Brazilian Jiu Jitsu techniques.

  • I studied here throughout my childhood. This is a place not only to learn self-defense, but to internalize the values that make someone a good martial artist and a better person, values like determination, courtesy, and accountability. Kids and adults can find great opportunities to train and improve themselves, whether it be in Karate, Jiu-Jitsu, or both programs.

Respect, discipline, and fallow commands, which in the long run we and the community develop fine young Men and Woman I have see many men, woman, and children come through those Dojo doors. some stay, and some leave. But the ones that stay turn out to be a GREAT parts of the community.

    Great place to train BJJ. Though the school is traditional, the curriculum is up-to-date and the instructors are very knowledgable. I would recommend this school to anybody who wants to learn self-defense or train for competition.

    I went to the East Montgomery Martial Arts academy all throughout middle school and high school. It taught me discipline, self control, and respect. I also gained an incredible amount of confidence knowing that I had the ability to defend myself. I would recommend that anyone interested at least come in and have a conversation with Mr. Exaros, it would definitely be worth your time.

  • I started training at East Montgomery Martial Arts when I turned 50. I wanted to switch up my workout routine and thought it would be a nice way to spend time with my teenage daughter. It is a great workout and a nice way to remove ourselves from the busyness of life. The discipline and respect that is taught in the dojo is invaluable to our young children and teenagers and will serve them well as adults.
