From the reviews

For almost 9 years, I've been part of Master Ken's Xtreme Martial Arts Center. I joined when I was 5, initially just looking for a way to stay active and have some fun. However, as the years passed, Taekwondo became much more than just a weekly class for me. It's been a source of mental and physical growth.

★★★★★ — Evonne, Jan 2024

This review is long overdue. Master Ken is absolutely awesome is everything he does! My son participates in his after school program where Master Ken or his very nice wife Mrs. Lee will come and personally pick up your child from school, help out with homework, and then do a lesson of Taekwondo.

★★★★★ — John, Jan 2016

Enrolling in Master Ken's school was one of the best decisions my wife and I have made for our son's development. Other family members attended this school and we enrolled based on their recommendations. Master Ken and his wife always greet you with a smile and make you feel welcome from the moment you enter.

★★★★★ — George, Mar 2015

Master Ken is knowledgeable and patient. He teaches at a steady pace and keeps all the students engaged and learning. My son loved his former Master Moncelsi and was devastated when he past. I did not pressure my son into going back. A year later my son saw Master Ken 's studio and asked if he could try.

Your first kickboxing class at Master Ken's Xtreme Martial Arts Center

Nervous about walking into a kickboxing 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 the basics — stance, footwork, and punches and kicks on pads or a heavy bag — not hard sparring. Go at your own pace and rest whenever you need to; no one will bat an eye. What to wear: comfortable athletic clothes you can move and sweat in, and supportive trainers. What to bring: water, and hand wraps and gloves if you have them — many gyms lend loaner gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves and wraps (and shin guards once you start sparring). Sparring is optional and eases in gradually, once your basics 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.

Kickboxing is a contact sport. Warm up, pace yourself, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
