My Story

I own a company named Apexx in Warner Robins, GA.


Apexx has served the Middle Georgia area since 2004 by changing the lives of thousands of people through Martial Arts, Fitness, After School and Summer Camp.  

I am currently a 6th Degree Black Belt in TaeKwonDo and a Blue Belt in Brazilian Jiu-jitsu.

In addition to being a Martial Arts student, Minister, teacher and writer, I coach and consult with other entrepreneurs on how to leave their Legacy through becoming a Best Selling author.

Apexx began when my 2 youngest kids decided they wanted to take TaeKwonDo.  Soon, I found myself running a Martial Arts club and working as a manager for JCPenney. In 2005, I left Penney's to operate the Martial Arts school full time.


Apexx is currently home to over 300 members. 


We are a part of Ultimate Leadership Martial Arts based in Springboro, OH.

My Books

"Our experience with WRMA has been great. My son is learning such great skills and character traits from his instructors. I love how they teach respect and discipline. I can tell that it's making him pay closer attention to adults. And he's setting goal after goal because he wants to be like his instructors. For me, I'm very happy because I'm seeing a lot of growth in him."
