From the reviews

had Sensei Andrew come work with our Daisy troop, and he was absolutely wonderful. The girls earned their Courageous and Strong petal, and this was exactly the type of experience I’m trying to incorporate into our troop instead of traditional sit-down lessons.

★★★★★ — Vicki, Feb 2026

I am a Daisy Girl Scout troop leader. This was a fantastic learning experience for the girls. Working with Sensei Andrew was easy. He described to me exactly what his course would offer to the girls and it was very easy to work with him regarding booking. The day of the class, Sensei Andrew was happy and pleasant.

Your first Karate class at Supreme 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.
