Great classes and people. Rex trains hard - excellent grapplers and fighters to choose from. Meli is absolutely an angel; Rex is too blessed honestly 😆. One recommendation I’d leave is to have the link to their “Email Meli” button on the contact us page. I tried emailing them but the link is broken. 🙌 thanks for the awesome shorts and the training/seminar.

I go to this gym mainly for their no-gi/folkstyle wrestling classes, and they’ve massively improved my BJJ game. The coaches are knowledgeable and friendly, the facility’s always clean and well-equipped, and the vibe is super professional but welcoming. Highly recommend this place if you want to level up your grappling!

Can’t imagine a life without martial arts anymore. Coach Rex runs an amazing academy. Definitely would recommend, whether you’re new or have been training for many years.

A no- nonsense place where you will learn the art of combat. There’s no kata, no unrealistic coordinated movement - sign up if you want to learn how to fight.
That being said, the instructors are humble and knowledgeable. Great place!

Great place to train, the instructors are very knowledgeable, everybody is friendly, no egos or anything. Plenty of classes throughout the week at different times in the day. Would definitely recommend Octo. If you're thinking about getting into combat sports and you have no background in it, just go in.

Great atmosphere, knowledgeable instructors, and a nice facility. Octō has a lot to offer whether you're advanced or stepping into the sport for the first time. The top priority is to learn and improve, but also maintains a lighthearted and personable atmosphere. If you're looking for advancement in a competitive career or just want to try something fast-paced and new, there's a lot for you at Octō.

Can't recommend enough as someone who was very new to thai boxing when I stepped foot into Octō. Instructors and fellow students aim to foster one another's growth and "take care of each other." An atmosphere very purposefully constructed by Kru Rex. You won't regret joining this academy.

Octō Alliance Combat sports is a phenomenal gym for both newer and more advanced fighters, the coaches are amazing, and take their time with newer participants by helping them with their form and technique, not only that but the sparing is perfect. I have been going to Octō Alliance Combat Sports for around a year and a half now and have absolutely fell in love with it's environment. Being able to attend this gym has pulled me out a really rough patch in my life and I will forever be grateful. If you are searching for a gym or are just looking for another gym to try out you should come down to Octō Alliance Combat Sports.

Please note, a gym that has great instructors and lacks business acumen will eventually disappoint. Octo Alliance has great instructors and the owners (Kru Rex and Meli) know how to run a gym.

Nice facility, private shower, changing rooms, small gym with weights and a rowing machine, plenty of thai pads, kick shields, loaner gloves, shin pads, etc.

There are a wide range of students at Octo. Women, men, older, younger, competitive fighters, and practitioners, so this is a great place if you want to compete, learn to defend yourself, or simply improve your health.

Kru Rex, and Instructors/Coaches James, Justus, Ryan are exceptional Muay Thai teachers...lighthearted, fun to be around, and helpful beyond expectations.

A friendly atmosphere all around, reflected by the students and instructors.

The Muay Thai foundations class on Saturday morning is amazing. Focused on technique and understanding as a whole. Coach James leads the foundations class with Kru Rex supporting...it's been great every session.

They have great merchandise and fight gear (multiple brands), at very reasonable prices.

Wanted to try a striking martial art for quite some time and was always apprehensive due to hearing stories of the way some striking gym’s conduct themselves and I must say Rex and the staff have created a great ego free environment where theres a big emphasis on taking care of your training partners. Overall very welcoming and I have been pleasantly surprised with my experience. I would recommend this gym for anyone to try.

It was very insightful and incredibly worth it. Definitely top teir instructors!

He works with everyone regardless of skill level and really reinforces good technique over power. This gym is the best in GR hands down.

Oh and they have showers so yes!
