From the reviews

I have 4 kids, from 7 to 16 that absolutely LOVE these classes. Sifu Jason is amazing with all of them, and his assistants/trainees/ more advanced students that help out are great also and held to the same high standard that Jason sets.

★★★★★ — Shiloh, Nov 2019

My girls ages 12, 15, and 17 take classes with Sifu Jason. They have only been going for about a month but they have learned a ton. Jason is patient and a great teacher. He builds their confidence and makes sure they are comfortable with all the techniques. I’m looking forward to also taking lessons soon.

★★★★★ — Sarah, Mar 2019

I’m working Siu Lim Tao with them right now. I like the class and Sifu Jason. We work the form and practical application. This has been good. Update: I’ve been training here twice a week for a few years now. The school has grown and remains a great place to train. My martial arts have improved immensely.

★★★★★ — Frank, Aug 2023

Update: I've been learning Brazilian Jujitsu here and it's been awesome. One of the best things is their ability to maintain a warm and friendly environment while providing top notch instruction. I've worked at many BJJ clubs before, but nowhere feels more like home than here.

New to BJJ? Start at Theta Combat Martial Arts

Theta Combat Martial Arts comes up as a beginner-friendly gym, going by their listing and members’ reviews. 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 Theta Combat Martial Arts

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.
