From the reviews

Sensei Charlie is an amazing instructor. He impresses me with his expertise in fighting, as well as his stories of his journey to a black belt. This is a great place to train. You will love it. It is like a family here and you are made to feel welcome.

★★★★★ — Mark, Jun 2019

Kenpō Combat academy is very clean and inviting. There is more then ample seating for us parents/Grandparents. Sensei Charlie has a friendly, funny and patient personality and is very good with kids. My Granddaughter Aubree loves it and looks forward to her classes.

★★★★★ — Nanakim66, Feb 2022

Love the training and the instruction is taught very well for all classes. My family and I will be here for a very long time!

★★★★★ — Jakob, Apr 2019

I attended Kenpō Combat academy for about a year and half, and believe Charlie is a great martial arts instructor. He explains the techniques very clearly and cover the reasoning behind each move, as well as what to do in a alternate situation.

Your first muay thai class at KCA Jiu Jitsu & Muay Thai

Nervous about walking into a muay thai 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 on pads and bags — not fighting. Rest whenever you need to; no one will bat an eye. What to wear: shorts or athletic wear and a t-shirt; you'll train barefoot on the mats. What to bring: water and hand wraps if you have them — many gyms lend gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves, wraps, a mouthguard, and shin guards. Sparring is optional and comes later, once your fundamentals 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.

Muay thai is a contact sport. Ease in, 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.
