    Brazilian jiu-jitsu is an engaging way to stay physically fit while developing discipline, confidence and self-defense skills. If you’re searching for a welcoming Brazilian jiu-jitsu studio or MMA studio, look no further than Lock Down Brazilian Jiu-Jitsu. Over eight years ago, we opened our first studio in Lake Ronkonkoma. Now, we’re excited to have a second studio in Hewlett, NY.

    Our owner is the only 3x World Champion in the surrounding five-town area and is an original Renzo Gracie team member. As a professional MMA competitor who has been teaching the sport for over 15 years, his goal is to bring world-class BBJ to this area.

    What do people say about us?

    • Professor Joe is a dedicated teacher who takes pride in helping his students reach their full potential. Lockdown has become a second home to me and my fellow students like family, all the result of the atmosphere Professor Joe has created.

      Peter J de Groot
    • What I believe that separates Professor Thompson out from other instructors that I have encountered is his dedication to all of his students. He not only gives the same amount of dedication to his high ranks and the people who compete, he gives this same level of attentiveness to any student who gets down on the mat that day.

    • Professor Thompson is a very knowledgeable, patient and detail oriented instructor. The students at Lockdown are very nice and easy going, making classes enjoyable. The academy is very well maintained and kept clean. Lockdown BJJ has a very family oriented atmosphere and I highly recommend it to anyone.

      Dan Castillo
    • Joe Thompson is an amazing person, great role model, and excellent instructor. He has helped me a ton in my Brazilian jiu-jitsu journey. Soo unbelievably motivated and reliable. He has always welcomed everyone with open arms, and will go out of his way to help. No doubt this school is going to be the best in the area to train and learn. Stop in for a class, you won’t regret it.
