Strength. Honor. Discipline.
At Berserkir Jiu Jitsu, we don’t just train techniques—we forge character.
Strength
We build strength of body and mind. Every roll, every rep, every round makes us harder to break.
Honor
We train with respect—for our coaches, our teammates, and ourselves. We win with humility and lose with integrity.
Discipline
We show up, stay consistent, and do the work. Progress is earned, never given.
Our Culture.
At Berserkir, you’re not just joining a gym—you’re joining a tribe.
We train hard, but we take care of each other. Ego has no place here. Whether it’s your first class or your hundredth competition, you’ll find a team that supports your growth every step of the way.
Meet Your Head Coach
Trey Rushing
head instructor
With over 20 years of grappling experience, Trey Rushing brings a deep, well-rounded approach to Jiu Jitsu rooted in both no-gi and gi training. He began his journey in 2004 and started teaching as early as 2009, building a strong foundation in both competition and instruction.
Throughout his career, Trey has trained extensively across the southern U.S., earning his blue belt under Sean Applegate with 10th Planet Jiu Jitsu, purple belt under Bobby Rivers and Scott Phillips with 10th Planet Jiu Jitsu. Then put on the Gi to earn his brown belt under Professor Jeremy Bond with Good Fight Dojo in 2025. His diverse background and commitment to continuous learning have shaped a versatile and adaptable style.
As a coach, Trey emphasizes understanding the “why” behind each technique—focusing on timing, mechanics, and real-world application. His goal is to help students not just perform techniques, but think critically, adapt, and grow on the mats.
Today, he leads with a passion for teaching and a belief that Jiu Jitsu is for everyone, from beginners to advanced practitioners.
First class is free! We currently offer fundamentals, gi, and no gi classes. Possible kids classes in the future pending interest.
