From the reviews

Glad I joined. Old school traditional Goju Ryu karate. Not many places teach this style anymore. Challenging and rewarding to progress in the style. Belts are earned, not given. Training here is a mental as well as physical experience and you will reap the benefits of you stick with it.

★★★★★ — Matt, May 2026

I've been training with this dojo since 2001. It's a traditional Goju Ryu karate school that teaches you the classic techniques while also practicing contact sparring safely.

★★★★★ — Tanay, Sep 2023

Kanzen Karate Academy changed the whole direction of my life. I went from a 20 yr old with no direction to a highly successful Attorney running his own law firm for 23 yrs. I know in my heart and soul I would not be here if not for Zoku Rosenstein and the other instructors.

★★★★★ — Keith, Sep 2023

I have been with Kanzen Goju Ryu for 24 years, since I am 4 years old. I credit Kanzen for me being where I am today. It has instilled in me focus, confidence, discipline, among many other traits. I highly recommend for all ages.

New to Karate? Start at Kanzen Karate School

Kanzen Karate School comes up as a beginner-friendly dojo — noted on their own site. If you've never thrown a punch or set foot in a dojo, 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 the sensei scales the intensity to you. Second, you won't be thrown into hard sparring — reputable dojos build fundamentals (stances, blocks, punches, and kicks) for weeks, and kumite (sparring) eases in gradually, with pads and control. Third, all levels and ages 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 dojos are happy to let you watch or try a class first, so reach out before you commit.

Your first Karate class at Kanzen Karate School

Nervous about walking into a Karate dojo for the first time? Almost everyone is, and a good sensei expects 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, punches, and kicks — not hard sparring. Step to the side 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. What to bring: water, and a mouthguard if you have one — many dojos 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 and the belt your dojo awards you. Kumite (sparring) eases in gradually, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the sensei. It gets easier fast — most people feel far more at home by their third class.

Karate is a contact sport. Ease in, train within your limits, 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.
