  • They have a wonderful program that starts around age 4, and continues through to whatever degree of black belt they choose to study for. This school teaches self discipline, courage, determination and dedication and helps to mold your child in to a strong willed and hard working adult. We love the school and all the instructors that help teach our children and make sure they get the best quality instruction that can be given. We love our Impact family!!

  • The instructors here are very supportive, and will bring out the best in every child. Program is very affordable and you can come as many times a week as you want. In addition, all belt testings are completely free of charge, unlike almost all other martial arts schools. I have trained at Impact Martial Arts (both warren and clinton schools) since white belt, and now hold a black belt 6 years later. For all of those 6 years, my instructors provided an encouraging atmosphere that motivated me to do my best every day. Great for all ages, from 4 year old peewees to adults (we have a great adult program too). If you are looking to take up martial arts, Impact Martial Arts is worth serious consideration.

  • The instructors here are so helpful and positive. They push you to work hard and challenge yourself but understand that some people need a little more time and practice than others. I started a short time ago as an adult who had never done martial arts before and I have learned so much in a couple weeks! I love that the adult classes have students of all levels so we can learn from everyone, and that every class is different. I definitely would recommend this school for fellow beginners who want to learn the art of taekwondo.
