From the reviews

Coach Jon is incredibly knowledgeable, patient, and truly invested in helping his students grow. Whether you’re brand new to Jiu Jitsu or have years of experience, you’ll feel supported from day one. If you’re looking for high-level instruction and a great atmosphere, this is the place to be.

★★★★★ — Isko, Jun 2026

I've been taking random drop-in classes with John for over 6 years. I speak from first hand experience when i say he is the best instructor i've ever had with BJJ. He has a wide range of battle test technique and a deep understanding of the game and metagame.

★★★★★ — James, Jun 2026

I’ve trained in combat sports for over a decade and Jon Calestine is the best coach I’ve ever had. The attention to detail he gives you and community he’s built is something special. It’s rare you get world class training coupled with nice people but that’s the environment Jon has built.

★★★★★ — Greg, May 2026

New to BJJ? Start at Calestine Jiu Jitsu

Calestine Jiu Jitsu comes up as a beginner-friendly gym — noted on their own site. If you've never rolled or set foot on a mat, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit or flexible to start — you get in shape by training, not before it, and coaches scale the intensity to you. Second, you won't be thrown into hard rolling — reputable gyms build fundamentals (positions, escapes, and basic submissions) for weeks, live rolling eases in gradually, and tapping early keeps every roll safe. Third, all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out, and leave your ego at the door. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first BJJ class at Calestine 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. 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.
