Our Martial Arts Instructors – The Not So Secret to Our Success

The best martial arts classes and programs in the world are of little value without highly trained instructors who can effectively relay the physical and mental skills associated with Karate to students of all ages and abilities.

This is especially true when it comes to teaching children.  It takes an extraordinary person to connect with children and our instructors are extraordinary.  All of the instructors at American Martial Arts Academy are certified, have completed at least two years of Martial Arts College and have been specially trained to work with and teach children.  They are some of the most qualified instructors in the martial arts industry and their commitment to helping other is beyond reproach.

Our instructors are all extremely proficient in the techniques of karate and have demonstrated the skills and ability to safely relay those techniques to students of all ages and abilities.  While physical skills are important, they pale in comparison to the life skills that martial arts and our instructors have to offer.

Our instructors and key staff members have grown up with AMAA and it adds another layer of authenticity to the values and family friendly vibe that students, families and their guests feel when they walk into one of our training facilities.

Our martial arts family is committed to helping each student be the very best person that they can possibly be and our instructors play a key role in maintaining that commitment on a daily basis.
