Master Cody Foor



To me, Martial Arts is an epic, mysterious adventure filled with excitement, challenges, secret knowledge, deep meaning, and purpose. I have been drawn to martial arts all of my life and have been involved in The Way for nearly 4 decades. I have had many excellent teachers and experiences during my life in martial arts, but my REAL journey began when I met Grandmaster Choe. Under the guidance of Grandmaster Choe, I have been able to experience martial arts as a student, friend, brother, competitor, champion, teacher, leader and master. Grandmaster’s ChungMu HapKiDo is a complete path, providing the ways and means for full development of body, mind, and spirit.

Personally one of the greatest joys in martial arts is helping others and witnessing the positive changes in students’ lives. The friendship and community that makes this powerful change possible is a living treasure. The respect in HapKiDo forges relationships with a level of consideration and regard that is rarely found elsewhere.

My life at Choe’s HapKiDo has come full circle with my 2 sons beginning their own journey in ChungMu HapKiDo. Martial Arts is a true force of good in the world, and it is an honor and blessing to be part of it.




Hello! My name is Crystal Stein, and my students know me as Instructor Crystal. My journey with Choe’s HapKiDo Martial Arts in Grayson, Georgia began in 2013 as a student, and since 2018, I have enjoyed becoming one of the owners and head instructors.

I began my martial arts career shortly after an alarming incident took place.  I was approached in a parking lot by a man asking for money. At that time, I was alone with my kids, and he was directly behind me and my opened car door before I was any of the wiser. It scared me into action. Once, I was home, I contacted my kids’ martial arts instructor and signed myself up for classes. The rest is history.

Reflecting on this one incident, I believe EVERYONE of any age can benefit from martial arts—HapKiDo specifically!

HapKiDo Martial Arts not only trains your body, but your mind and spirit as well. It has taught me the importance of having an indomitable spirit, and it has also made me a better mom through the practice of mindfulness.

A couple fun facts about me: I became a black belt in August of 2016, while I was 20 weeks pregnant.  While I am still pursuing my second degree, my husband and 4 of my 7 kids are also black belts. It’s safe to say that HapKiDo plays a HUGE role in my daily life.

To every person out there interested in martial arts, I encourage you to go for it! Not only does it teach self-defense, but the confidence and real world applications it teaches makes us stronger and more well-rounded. If you are unsure that HapKiDo is for you, come try our life-changing program with a free trial! Martial Arts may be the thing you’ve been looking for to help balance your life, much in the same way it has for me and every student who has walked through our doors. I hope to see you soon!




Hello! My name is Paul Moore Jr., and my students know me as Instructor PJ. I began at Choe’s HapKiDo Martial Arts in Grayson, Georgia in June 2017, and it has been a blast growing as a martial artist. It was a proud day to have earned my black belt in October 2019.

I was always a lifelong fan of martial arts, and I fell in love with HapKiDo! When I started as a student, I was 41, out-of-shape, overweight, and not very flexible. Within a few months of enjoying taking classes with my 2 kids, I started losing weight and felt better than ever!

What I really like about Choe’s HapKiDo is the philosophical teachings. It gives me an opportunity to grow physically, mentally, and spiritually. The life lessons learned here are applicable to everyday life, and you become more self-aware with how you interact with others, yourself, and surroundings. What we learn here is hard to find elsewhere.

The greatest aspect of being a martial artist instructor—or at least, what I love the most—is watching our students grow, but also a being a part of their journeys as well!

From overcoming my own obstacles, I encourage you to give Choe’s HapKiDo Grayson a try! Everyone here is ready to help you reach your goals, and it’s a positive community to become a part of. I hope to see you soon!
