"Excellent place to train! The instructors are incredible; both friendly and professional, providing detailed demonstrations of technique with nuanced explanation of concepts in ways easy for anyone to grasp. Combine this with a great environment and awesome students/training partners and you have Dominion BJJ. Whether you are experienced or new, training for competition, self defense, or recreation, I highly recommend Dominion BJJ and consider myself lucky to be a part of this team and gym."

Michael K.

"Very welcoming environment. I came in knowing nothing about grappling and with no athletic background, but Bill and the rest of the team happily worked with me and opened me up to the beautiful art of Brazilian Jiu-Jitsu. Highly recommend!"

Steve A.

"Bill Nagle and Michelle Welti are amazing. Bill is amazing with his techniques and instruction. He is one of the most consistent/thorough instructors I have trained with. Michelle is an awesome competitor and great instructor as well!"

Micah F.

"I have known Bill for a long while and his ability to excel in the martial arts has been staggering. You could search the entire area and never hope to find a more patient and genuine instructor. I wish Dominion all the best!"

Scott M.

"I've been training with these guys for about a year and half now and have nothing but good things to say about the experience so far. Bill and Michelle are both fantastic teachers, and will spend as much time as you need helping you perfect a given technique. Same with the other higher ranked students; I always feel like I can ask for help if I'm struggling to get something right. It's a very welcoming environment, and I would recommend it to anyone looking to do BJJ either competitively or just as a way to stay in shape."

Justin J.

"I trained with Dave, Bill, and Michelle for over 2 years. When my daughter is old enough, Dominion is the only place we will go to train. These are amazing individuals that welcome you, train you, and grow with you along your BJJ journey. I couldn't have asked for a better experience."

Matt L.

"The instructor Bill is very detailed oriented. He breaks technique down to where anyone can understand it. Great school. Michelle is also a wonderful kids instructor. By far the best school in Northern Virginia as far as BJJ. I have a blog called the Activity Bus where I rate schools and promotions. Trust me when I say it's the best."

Jose M.

"One thing most people fear is trying something new, it makes them uncomfortable or nervous and makes it hard to be successful. Everyone at this gym are very welcoming and makes starting BJJ easier or if you have trained previously gives a great relaxed environment to train. Bill Nagle is a great coach and doesn't leave a detail out when teaching a new technique. The amount of knowledge possessed by the coaches is outstanding. Everyone is so friendly and it's like having a second family at the gym. Be sure to stop by and try out a class, it could change your life!"

Hasan K.

"This is a great, welcoming place to train. I came in not knowing a thing about BJJ. I gained a wealth of knowledge and a second family here. Sadly I had to move from the area but I always enjoy visiting and training. If you're near Manassas and looking into BJJ, check this place out! Bill is an amazing instructor."

Josh P.

"Came in lookin for a way to lose weight and get in shape for me and a place for my daughter to learn self defense techniques every girl should know to protect them from assaults by larger stronger opponents and was completely satisfied! What I didn't know was that Brazilian Jiu-Jitsu is a life changing sport with an amazing community of cool people who are also kind. Bill and Michelle are awesome instructors for both adults and kids. I recommend Dominion Brazilian Jiu-Jitsu whole heartedly."


"Up close, hands on, personal instruction from the the most experieced and highest ranking instructor in the area. Very beginner friendly Whether your goal is to compete - like me - to learn brazilian jiu-jitsu for self-defense purposes, or just to get in great shape and make a great group of friends, this is the best jiu-jitsu program in the area to help you reach those goals. So don't wait. I only wish I started training here sooner and, if you wait, you will too."


"Great gym for kids martial arts and adult and kids Brazilian Jiu Jitsu, which has been my experience at their current Manassas location and previous locations. Top notch personal training. Very friendly place."


A great place to learn Brazilian Jiu-Jitsu! Being a girl I was a little intimidated about going into a mixed class but everyone is so warm and welcoming. Instructors are patient and give advice to better your technique and are always willing to answer your questions. Very friendly and positive environment.

When I first started training Jiu Jitsu with Team Dave Trader back in 2009, I was a 265 pound “wannabe” gangster. Training with Dave and his team has changed my life in more ways than I can describe in a short testimonial. Within just a few months I was so much more athletic and flexible than when I started. After only 8 months of training (and 2 months of dieting) I had lost over 40 pounds. I also feel like I matured into a much more focused and responsible person because of the people I was surrounded by in the gym – it is truly a great group of people. Everyone on the team has been willing to me and offer advice both inside and outside of class. Now at a muscular 205 pounds, I am proud to say I am a team member and competitor at Dave Trader Jiu Jitsu.

I can’t say enough good things about the kids Jiu-Jitsu program at Manassas MMA, led by Michelle Welti. My wife and I were looking for a legitimate gym for our 6 year old son to start his walk with mixed martial arts. We have definitely found that at Manassas MMA. Witnessing the growth in our son’s self-confidence, respect for others, and discipline has been amazing! Michelle has a way with kids that many people don’t; this makes her perfect for the job. As a parent, words can’t describe how awesome this is. Some people just have a gift for teaching and working with children, and Michelle is by far one of those people.

I went to try out BJJ with a friend of mine who had been training there for a while, and after my first class I knew I was going to join. Dave Trader was highly recommended to me as an instructor by a well trusted friend who had trained under Dave a few years prior. I had always been interested in BJJ, but never had the time, and was a little scared of starting at a new school with new people. I instantly felt like I was at home with the family at Dave Trader Jiu-Jitsu. The school runs with a very laid back atmosphere, which is a must for me. I’m not into the militant-style training that some other schools offer, as BJJ isnt really that type of art. It’s a very technical martial art, unlike any other. It is inspiring and comforting to know that I am learning from a seasoned competitor who has competed at the world class level, and knows how to teach both the fast paced competition game, and the flowing, smooth, and technical game that i have come to love.

In the short amount of time that I have been training with Dave, my jiu-jitsu game has improved dramatically and I am already competing! I am also training Muay Thai and MMA. Being able to get the full training I need to be a successful combat sports athlete all in one place is something that is truly hard to find. I would recommend Manassas MMA to anyone. Whether you are looking to lose weight, compete, or join a great team atmosphere, Manassas MMA has it all.

I have been training at Manassas MMA for almost 2 months now and I can say with confidence I have never received training in a better environment or from a better staff of instructors. The very first time I walked into the gym, I was very nervous about training with a new group of instructors and teammates. That feeling was immediately erased as I was welcomed by all the coaches present upon entering the gym for the first time. The coaches that arrived later made time to welcome me as a new student which made me feel much more at ease about training with all these new instructors.
Just as class was about to start, all the current students also made time to welcome me as a new student. This really reassured me that I wasn’t just fresh meat coming into the gym.

During my first training session, head instructor Dave Trader taught techniques that are fundamental to being successful in Jiu-Jitsu, in a way that made clear sense to me and the other students present. Assistant instructors Bill Nagle and Michelle Welti also have years of experience and training, and assisted in teaching these techniques in a clear concise manner. Throughout class, my training partners never once treated me as if I was just a new kid. They spent the time to ensure I was practicing the techniques properly during drilling sessions, as well as explaining why I should do the techniques specifically the way it was shown.

I was extremely nervous about sparring for the first time in a Gi, because it was something I had no experience doing. Once again my training partners did not use this as a chance to beat up the new kid. They were proactively showing me how I would do things in a competition match situation while remaining active and teaching me how I should defend. None of my training partners ever put me in a submission hold in a way that it would be seriously painful. Manassas MMA has the best balance of a friendly environment mixed with experienced instructors to make all new students become successful in training. I have noticed a dramatic improvement in my technique after only 2 months of training. I couldn’t ask for a better place or better instructors.
