About Our School

Welcome to the KarateBuilt Grand Rapids website! You have found the right place for you and your family to do martial arts. KarateBuilt™ martial arts schools offer classes for pre-school kids and elementary age children in addition to our famous ATA programs for teens and adults. The programs include beginner martial arts, advanced Black Belt classes, leadership training and instructor certification.

In the renowned Karate For Kids™ programs, the children are taught age relevant curriculum to help them build self-esteem, increase personal self-discipline, get fit and of course be safe from bullying and other dangers that kids face in today’s world. These classes (unlike most kids activities) are taught by full-time professionals who are background checked and trained for hundreds to thousands of hours during the course of their instructor training.

In our Adult and teen classes some of the students have goals to lose weight or get in shape. Others want a high-energy workout to complement other sports or hobbies. And other students want to dedicate themselves to being safe!

We always offer a full-time professional staff, classes 6 days a week, and a curriculum that is based on making the individual succeed all while learning life skills like respect, discipline and communication.

For our adult students: Adults have a wide variety of goals when they start here.

The instructors at KarateBuilt™ Martial Arts work with you individually so that each of these goals can be met.
