Amanda Dowell

Kickboxing and Fitness Coach

Amanda is a Nursing Home Administrator who joined Champion Striking in May 2019. I started training at Champion Striking and Fitness in May of 2019 with zero experience in any type of Martial arts. What started as a workout quickly became a passion. Not only were the classes fun they were designed for people of all experience levels. I was welcomed into a wonderful community of people that I call my teammates. They helped hold me accountable and encourage me. After starting in 2019, I have lost 45 pounds and feel better than I did 10 years ago. Champion Striking and Fitness changed my life. Amanda has completed the Champion Striking Kickboxing Certification Course.

Joey Dishman

Joey started training kickboxing and Jiu jitsu in 2013 to help his children learn martial arts for self-defense. He didn’t realize how much he would enjoy it and stay dedicated for so long. He currently coaches the 6 am morning classes and is a brown belt in Jiu jitsu. Joey completed his kickboxing certification in Feb. 2022. Through the process Joey has learned many aspects of the kickboxing practice and enjoys helping others learn the technique.


“I never thought that I would enjoy kickboxing as much as I do and teaching others has become my passion. One of the biggest accomplishments as a coach is to see your students grow in the sport that they never thought they would.”

Tina started her kickboxing journey in 2018.

She likes coaching students of all ages and fitness levels. She enjoys observing the progress of seeing the students evolve into their full potential. One of her greatest accomplishments has been stepping into the ring at 42 to compete in her first fight.
