OUR HISTORY
Ms. Shelly Deterville
Courage Martial Arts Owner
Courage Martial Arts was established in 2007. Prior to that Ms. Deterville helped develop a nationally recognized Martial Arts program for children and families with bleeding disorders, cancer and other serious medical conditions. As a nurse, Ms. Deterville was able to share her love of martial arts in a safe setting that allowed these families the opportunity to experience martial arts first hand; no one had to sit out. The courage of these families is what inspired the name of our studio, Courage Martial Arts.
In 2014, she wanted to share the philosophy of CMA with as many people as possible and that is when she chose to teach Martial Arts full time and moved to our current location on Main Street in Green Bay. We are a family run school that values a positive environment.
On a personal note, she has 3 grown boys who are all Black Belts and 5 grandchildren. She loves spending any opportunity with her family. She also feels fortunate that she gets to work with her mom (Mrs. Radtke) everyday!
Courage Martial Arts is dedicated to teaching martial arts to anyone who has the heart and willingness to learn. Every student is considered a member of our family. On the way to earning their black belt students will discover their focus, confidence, discipline and self-esteem know no bounds.
