What members say
“She hates the idea of anyone getting hurt, and Griffin kenpo's emphasis on Chin Na (joint lock techniques) fits very well with that.”
“My daughter has grown in self-confidence, is stronger and more self assured.”
“My son has learned not only the skills and techniques but more importantly the discipline and principles behind martial arts.”
From the reviews
My 11 year old daughter and 5 year old son have both attended Ethereal Arts for just over a year now. My daughter attends the Kids Kenpo Karate class and my son, the Little Griffins, they both enjoy every minute. The tuition given by Master Frost and Sensei Mike and Jeff is excellent in my opinion.
In addition to being well skilled in teaching kids in Kenpo karate, Sensei Frost and his team (including the senior back belt students who coach at times) provide a highly positive, nurturing environment in the dojo.
Both of my kids practice at Ethereal Arts Self Defense in Stow and they love it. The after school program is fantastic - with pick up direct from school and an afternoon of activities before the evening class.
The classes fit my schedule and the instructors are respectful and happy to discuss accommodations for any special needs. The two week free trial gave me a chance to see if the courses, instructors, and school culture worked for me. I’ve made progress in a short time.
New to BJJ? Start at Ethereal Arts Self Defense
Ethereal Arts Self Defense comes up as a beginner-friendly gym — noted on their own site. If you've never rolled or set foot on a mat, 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 coaches scale the intensity to you. Second, you won't be thrown into hard rolling — reputable gyms build fundamentals (positions, escapes, and basic submissions) for weeks, live rolling eases in gradually, and tapping early keeps every roll safe. Third, 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, and leave your ego at the door. Most gyms are happy to let you watch or try a class first, so reach out before you commit.
Your first BJJ class at Ethereal Arts Self Defense
Nervous about walking into a BJJ gym for the first time? Almost everyone is, and good coaches 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 positions and escapes with a partner — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many gyms lend a loaner gi for a first class, so it's worth asking when you call. As you keep training you'll add your own gi (or a rashguard and shorts for no-gi) and a mouthguard. Live rolling eases in gradually, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.
