From the reviews

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.

★★★★★ — Alyssa, May 2025

The instructors are extremely knowledgeable and helpful. Very fun learning environment. Mats are kept clean. Very respectful atmosphere. Great for kids and adults, men and women.

Your first BJJ class at Ronin Jiu Jitsu

Nervous about walking into a BJJ gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling basic positions and escapes with a partner — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many gyms lend a loaner gi for a first class, so it's worth asking when you call. As you keep training you'll add your own gi (or a rashguard and shorts for no-gi) and a mouthguard. Live rolling eases in gradually, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.

BJJ is a contact sport. Ease in, tap early and often, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
