★★★★★ — Kelvin, May 2021

The best Taekwondo in the Diamond Bar. The master Hong is very professional and knowledgeable for his field. This is the only one studio which has been in this area longer than 10years. Master Ryan is funny and friendly. My daughter loves to go here.

★★★★★ — Cindy, Jan 2020

★★★★★ — Chulkyeun, Feb 2023

Love this place! My son always looks forward to coming to his class. Feels very safe. Students are regularly checked for temperatures and asked to sanitize their hands. The teacher is amazing! He knows every student by name and with the right amount of being strict and playful.

Your first taekwondo class at All Star Taekwondo

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.
