From the reviews

I went to the women empowered seminar and was not sure what I was getting myself into. I went into it with an open mind but my mind was blown by Stevens Defense Academy. Tricia and Nate were both welcoming, knowledge and willing to make accommodations to make sure the entire class was able to participate.

★★★★★ — Sami, May 2022

My whole family absolutely loves Steven’s Defense Academy! 4/6 of us are in the various classes, Little Champs, Jr. Grapplers, and Combatives. They also offer a women’s only self defense class, which I was previously in and absolutely loved!

Stevens defense academy is great for not only kids but for the family as a whole. They are very much family-oriented and they take great attention to make sure that you were properly learning the correct way to execute your moves without you or anyone else getting hurt in class they also offer private lessons.

I enrolled my daughters in Ju Jitsu with Steven’s Academy of Defense about six months ago, and it has been an incredible experience for them! They absolutely love it. The class focuses on engaging defense techniques, which not only teaches them valuable skills but also boosts their confidence significantly.

New to BJJ? Start at Stevens Defense Academy LLC

Stevens Defense Academy LLC 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 Stevens Defense Academy LLC

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.
