About Karate Atlanta Marietta in Marietta, GA

John Michael Dietz

Chief Instructor at Karate Atlanta Marietta in Marietta, 3rd Degree Black Belt

Karate Atlanta Marietta is nestled in the East Cobb/Marietta area, right off Roswell Road, and is proud to be one of the newest locations in the Karate Atlanta family.

As a part of the ATA (American Taekwondo Association), we teach Songahm Taekwondo - a fast paced style of self-defense based martial arts which focuses on personal development, powerful and impressive kicks, blocking, and smooth transitions from rank to rank.

Total beginners welcome! We love to work with beginners and elite athletes alike. No matter what your starting level is, you'll get an amazing workout, gain lean muscle, and learn techniques to keep you and your family safe. Children, beginners with no martial arts background, and people with martial arts experience all excel and learn in an environment that is friendly and fun.

A sneak peak into our classes - controlled, fast-paced, and fun! As you build up your cardio endurance in ways previously held secret by top martial artists, you'll also build strength and coordination through super super-fun striking, defending, and flexibility drills.

Some other added benefits both our kids and adult members experience are:

  • Boosted Self-Esteem

  • Body Confidence

  • Better Teamwork & Goal Setting Skills

  • Outrageous Core Strength & Hip Mobility

  • Improvements in Stress Reduction

Knowing how to defend yourself and being physically fit builds confidence and self-control - for both adults & kids alike!

You'll become part of a legendary legacy through Martial Arts.Thanks to our top-notch and knowledgeable staff, our growing and motivated student base (and their supportive parents and families!) are fast becoming one of the top martial arts academies in the Marietta/Cobb County area.

We are committed to excellence, both on the training floor and off: mentally, physically, academically, and in terms of character development. Our drive and energy is evident from the level of leadership and instruction, to seeing our students grow as martial artists and even as black belt leaders later on.

We are constantly seeking to improve: ourselves as teachers and martial artists, our students, our school, and our community.

We would love for you to train with us and join our Taekwondo family: when we say "family" we mean it. The ancient art of taekwondo is more than a sport. It's a lifestyle, a community, and a passion worthy of pursuing for generations to come.
