Lionheart Jiu Jitsu
At Lionheart, we teach authentic Brazilian Jiu Jitsu, rooted in the art’s evolution from traditional judo to the highly effective grappling system refined in Brazil. BJJ isn’t about size or brute force—it’s about technique, timing, and heart.
Our training is designed for real-world readiness, not just competition. Whether you’re preparing for a match or facing life’s everyday challenges, Lionheart is a place to build confidence, skill, and resilience.
We keep ego off the mats. Our students train in a culture of respect, teamwork, and growth—because when we lift each other up, we all get better.
Certified Demian Maia Jiu Jitsu Affiliate
At Lionheart Jiu Jitsu, we’re proud to be a certified affiliate of Demian Maia Jiu Jitsu (DMJJB)—led by world champion and UFC veteran Demian Maia, one of the most respected names in Brazilian Jiu Jitsu and mixed martial arts. His career speaks for itself, with world-class accomplishments in both the BJJ and UFC arenas.
As a DMJJB affiliate, our academy has direct access to Demian Maia’s proven fundamentals curriculum, which we integrate into our beginner classes. This means our new students aren’t just learning random techniques—they’re building their skills on a rock-solid foundation, shaped by one of the best grapplers in the world.
Our affiliation also reflects our broader commitment to precision, safety, and structured learning. Whether you’re starting your journey or looking to refine your foundation, you’ll be learning under a certified system trusted by professionals and hobbyists alike.
Train where fundamentals are champion-built—and taught with purpose.

We believe in keeping training accessible, with pricing that allows anyone who has the desire to learn a chance to step onto the mats. Our focus is on people first, not profit.

Lionheart is also an active force in the community, offering self-defense programs, trauma-aware training, and outreach to help others grow stronger both on and off the mats. We encourage cross-training at other academies to strengthen the larger martial arts community, because growth is best when it’s shared.
