Evan Christiansen
Owner / Head Instructor
Evan began his Brazilian Jiu-Jitsu journey over 10 years ago and has dedicated his life to mastering the art. In 2025, he earned his brown belt under the legendary JT Torres, a multiple-time world champion and one of the most respected figures in BJJ.
With over 8 years of teaching experience, Evan has worked with students of all ages and skill levels—from children just starting their martial arts journey to adults pursuing competitive goals. His patient, detail-oriented teaching style emphasizes proper technique and helps students build confidence on and off the mat.
Before dedicating himself fully to BJJ, Evan trained and competed in Judo for 6 years, bringing a unique perspective to his grappling instruction. This diverse background allows him to teach effective throws, takedowns, and transitions that complement traditional BJJ techniques.

Our Philosophy
Technique. Community. Growth.
Technique Over Strength
Brazilian Jiu-Jitsu is known as "the gentle art" because it emphasizes leverage and technique over brute force. This makes it accessible to people of all sizes and fitness levels.
Community First
We believe that a strong community is the foundation of great training. Our students support each other, celebrate victories together, and grow as a team.
Continuous Growth
BJJ is a lifelong journey. Whether you're aiming for your first stripe or your black belt, we're here to guide you every step of the way with patience and expertise.
