Alyssa Turner
"Ronin Jiu-Jitsu has been a life-changing experience for both me and my five-year-old daughter. From the moment we stepped in, we felt like part of a family. The environment is warm, supportive, and built on respect—and that energy flows from the coaches down to every student. My daughter is thriving in the kids’ class. The coaches have a special way of connecting with the kids, making each class fun while still teaching focus, discipline, and valuable self-defense skills. She’s become more confident, active, and proud of herself—and she genuinely can’t wait to go to class every week. I joined the adult class and it’s been just as rewarding. Coaches Ernest, Rendell, and Tara are amazing. Each brings their own strengths to the mat, and together they create a perfect balance of challenge, encouragement, and technical instruction. Whether you're new or experienced, they make you feel seen, supported, and motivated. What makes Ronin special is the sense of community. It doesn’t matter your age, experience, or background—everyone is welcomed and treated like family. Being able to grow alongside my daughter in a space like this has been incredible. I couldn’t be more thankful to be a part of it."
