From the reviews

I've been training in martial arts since 1987. I had taken a break from formal training in 2014 until I attended one of Sensei/Sifu/Guro Raffi Derderian's seminars. I continued as a seminar student until 2023 when I decided to join regular adult JKD and Kali classes. I was determined to stay a seminar student.

★★★★★ — Dee, Jan 2025

I normally don't give reviews, but this martial arts school has earned my 5 star rating. I have been in martial arts all my life and have been currently training in this dojo for more than a few years now.

★★★★★ — Austin, Jan 2025

We are really happy with this karate school! The instructor is very friendly while also teaching the children discipline and respect, which I truly appreciate. I love seeing how he makes sure all the kids participate equally and keeps them engaged throughout class.

New to Karate? Start at Derderian Academy of Martial Arts

Derderian Academy of Martial Arts 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 Derderian Academy of Martial Arts

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.
