Embrace the Tribe: Your Brazilian Jiu-Jitsu Family is Here

I'm overjoyed to welcome you into our dojo, my friends! We're a spirited and lively assembly of Brazilian Jiu-Jitsu enthusiasts, just like you, dedicated to the pursuit of this extraordinary martial art. Our dojo, radiating energy, passion, and a dash of humor, has been the pulsating heart of our local community for many years. This place is more than just a gym; it's a family, bound by sweat, endurance, and the shared ambition of personal growth.

From Humble Origins to Jiu-Jitsu Mastery

My narrative began over twenty-seven years ago when I, a lifelong devotee of martial arts, envisaged creating a space where Brazilian Jiu-Jitsu could be both accessible and enjoyable for all. What sprouted as a small band of committed practitioners has flourished into a vibrant community of diverse individuals, all united by their love for this inspiring martial art. Over the years, we've laughed, learned, and evolved together, forging countless memorable moments both on and off the mats.

Professor Gilbert Ariza achieved the rank of Black Belt in Brazilian Jiu-Jitsu from Master Carlos Machado in 2008. With over 25 years of exceptional training in Brazilian Jiu-Jitsu under Master Carlos Machado, Professor Gilbert brings a wealth of knowledge and authentic Carlos Machado Brazilian Jiu-Jitsu to CMJJ Headquarters.

As an instructor, Professor Gilbert is renowned for his commitment to the art of BJJ and his skill in guiding students of all levels, from beginners to experienced practitioners to reach their personal best on the mats. 

His Brazilian Jiu-Jitsu approach emphasizes technical accuracy, ensuring that students establish a solid groundwork in the essential techniques of the art.

His expertise and enthusiasm for Brazilian Jiu-Jitsu make him an invaluable part of the teaching team at the academy, where he contributes to creating a supportive and challenging learning environment. He shares the same mission as Master Machado of changing lives through the martial arts.

I’m Gordon Chapin, a dedicated Brazilian Jiu-Jitsu black belt and coach with more than a decade of experience immersed in the sport. My journey began in 2007, and from the very start, I worked tirelessly to develop my skills, quickly making a name for myself by competing in and triumphing at numerous prestigious tournaments across the country.

My athletic background as a former football player and wrestler has undoubtedly contributed to my success, providing me with a unique perspective and a strong foundation that allows me to excel in both Gi and No-Gi competitions.

Today, I take immense pride in my role as a coach at CMJJ Headquarters, where I enthusiastically continue to share my passion, knowledge, and expertise with eager students, helping them to achieve their own goals in this incredible martial art.

I am an exceptionally skilled and passionate martial arts instructor with over 28 years of dedicated practice. I specialize in kickboxing, judo, karate, Brazilian Jiu-Jitsu, Muay Thai, and conditioning. Teaching is my greatest passion, and I take pride in passing my knowledge on to others.

I hold a 2nd-degree black belt in Brazilian Jiu-Jitsu and will be testing for my 3rd Degree Black Belt in Carlos Machado Jiu-Jitsu in April 2025. I am certified by the IBJJF to teach and referee Jiu-Jitsu. Over the past 28 years, I have had the privilege of teaching both kids and adults, shaping skilled practitioners and confident individuals.



As an accomplished competitor and instructor, I am thrilled to be teaching CMJJ Fit classes to help students achieve their self-defense, strength and conditioning goals. I strive to inspire and empower my students, helping them succeed both on and off the mats. Honored to be on Team CMJJ!

Hello! I'm Coach Ray Machado, Master Carlos Machado's eldest son and the Head Kids Instructor at CMJJ.

I focus on instilling discipline, respect, and leadership in my students, both on and off the mat. My wrestling background allows me to enhance their grappling skills through takedown techniques. As a former Basic Machado Jaguar member and now a respected coach, I am committed to continuous improvement in my BJJ skills, teaching methods, and nurturing my students.

Some of my achievements are:

• BJJ training since age 3

I’m Kieran Lermer, an instructor at CMJJ, born and raised in Dallas. My Brazilian Jiu-Jitsu journey began at the age of 4, and since then, it’s been a lifelong passion. I’ve dedicated myself to the art, earning my Purple Belt through years of hard work and commitment. One of the most rewarding aspects of BJJ for me is witnessing and being part of the growth and development of each student.

In addition to teaching, I actively compete and coach at tournaments, which constantly sharpens my skills and deepens my understanding of the sport. I’m truly passionate about the CMJJ family and what we represent, and I’m always eager to roll, chat, or support fellow practitioners.
