Martial Arts for the Whole Family

Unleash Your Potential

We use martial arts to help unleash your potential by improving fitness, confidence, and the ability to defend yourself while connecting you to a community of other positive, motivated people.


We are the premiere Mixed Martial Arts gym in Duluth, GA (Gwinnett County) founded and led by Bellator Welterweight Champion, Douglas Lima and brother Dhiego Lima, former UFC Welterweight contender.

As part of the American Top Team family of MMA schools, we offer a broad mix of disciplines including Cardio Kickboxing, Brazilian Jiu Jitsu (bjj), Striking (Muay Thai / Boxing), Advanced MMA, and a world-class Kids Martial Arts program. These programs are designed for people of all levels, experiences, and ages from absolute beginner to world-class competitor.

Our experienced and professional team will help you achieve your goals.  Above all, we believe martial arts will improve every aspect of your life and help you unleash your potential.


Whatever martial arts program you pursue, you will get in the best shape of your life.  You’ll torch fat and calories while building aerobic and anaerobic conditioning.  All of our programs are mentally engaging.  Therefore, you’ll never be bored and always looking forward to the next one.


You’ll have a new belief in yourself that comes from the confidence you’ll gain through martial arts.  This confidence transcends sport and impacts every area of your life because it helps you believe in your ability to succeed in anything you try.  Above all, this will help you unleash your potential.

Self Defense

Through Mixed Martial Arts (MMA), you will learn the most important forms of fighting technique from both striking and grappling disciplines.  In addition, you will learn to remain calm in the most stressful of situations which is essential to effective self defense.


At ATT – Team Lima, we believe in Martial Arts for the Whole Family.  We foster a welcoming and positive environment.  In other words, you’ll be surrounded by a driven, positive, and supportive community to help you reach your goals.

“In my opinion, American Top Team is the BEST MMA camp in the country!”
– UFC Commentator Joe Rogan


American Top Team

As one of the most successful MMA teams in the world, American Top Team sets the standard for excellence that few gyms worldwide can match for both athletes and coaches.  While American Top Team has a large stable of professional and accomplished athletes and fighters, the vast majority of the American Top Team family are hobbyists who train martial arts for fitness, confidence, self defense, camaraderie, and fun.  In other words, American Top Team is for everyone.  Our motto is:

“Martial Arts For the Whole Family”.











If you live in the Duluth area, come try out any program and us --- on us. No cost nor obligation. We'll provide everything you need.


The supportive atmosphere alone is 10/10 🙌🏼 In addition, top tier coaching and teammates that genuinely want to not only improve themselves but also others!

My husband and I also signed our daughter up for the kids program which she looks forward to going everyday! Watching how incredible the coaches are with her and seeing her confidence grow makes this mama extremely happy!

In conclusion, if you’re looking for a gym to feel like home, this is it!!

Firstly, it’s the Mecca of Georgia MMA. Douglas and Dhiego Lima are role models. Norman Simoes is a fantastic black belt instructor and mentor. Devon has a heart of gold. Sid has wisdom and experience. Brantley is a positive force. Gaby is so kind and motivating. Jerry will be forever missed.

We are a brotherhood and sisterhood. Everyone is family. I have never received more support through tough times from any other gym. Bottom line, being here is therapy and has literally saved my life. 🙏🏽
