★★★★★ — Madelyn, Aug 2025

This was very first time school experience for our three and half years old kid. Extremely happy with the classes here. Mr. Groce, Ms. Nash and their staff, all are very hard working and lovingly towards the kids. They give proper attention to every kid patiently and teaches accordingly.

★★★★★ — Shakti, Apr 2021

My kids started their Tiger Rock journey in another state but were lucky to land in Mr. Groce's school when the military stationed my in his area this past year. He runs an exceptional program and is a dynamic teacher.

★★★★★ — Michael, Apr 2018

Tiger Rock Marietta has been the most amazing experience for our elementary age son. He’s learned discipline and leadership in addition to the skills he’s been taught in his classes. The instructors are patient and kind. They also push their students to be the best they can be.

New to taekwondo? Start at Tiger-Rock Martial Arts of Marietta

Tiger-Rock Martial Arts of Marietta comes up as a beginner-friendly school — noted on their own site. If you've never trained or set foot in a dojang, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit or flexible to start — you get in shape by training, not before it, and instructors scale the intensity to you. Second, you won't be thrown into hard sparring — reputable schools build fundamentals (stances, blocks, kicks, and basic forms) for weeks, sparring eases in gradually and with gear on, and instructors keep it controlled and safe. Third, all ages and all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most schools are happy to let you watch or try a class first, so reach out before you commit.

Your first taekwondo class at Tiger-Rock Martial Arts of Marietta

Nervous about walking into a taekwondo school for the first time? Almost everyone is, and good instructors expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling basic stances, blocks, and kicks with a partner or on pads — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: loose athletic wear you can move in (or a dobok if you have one); you'll train barefoot on the floor. What to bring: water and a positive attitude — many schools lend a loaner dobok for a first class, so it's worth asking when you call. As you keep training you'll get your own dobok and belt, and sparring gear (mouthguard, headgear, and guards) once you begin sparring. Sparring eases in gradually, once your fundamentals and forms are solid. Arrive 10–15 minutes early to sign a waiver and meet the instructor. It gets easier fast — most people feel far more at home by their third class.

Taekwondo is a martial art and a contact sport. Ease in, listen to your instructors, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
