From the reviews

I have been training at Velez Jiujitsu for two years. In those two years, I have grown fond of the people who train at Velez and have considered Javier Velez a friend. The school is very technical in its teaching but very relaxed in its atmosphere.

★★★★★ — Juan, Mar 2023

I’ve personally trained with Prof. Velez for over 12 years and we are now both black belts. I can honestly say that he is one of the most giving and compassionate practitioners/instructors that you can find anywhere.

★★★★★ — Bruce, Nov 2018

For any military active/veterans, Velez Jiujitsu has been the best school I have ever had the pleasure of training at. The vibes are always positive; all of the professors, coaches, and training partners are kind, understanding, and push you to succeed in the most supportive way.

★★★★★ — C, Nov 2018

This review is for my son's Jiu-Jitsu class. Coach Velez is exceptionally knowledgeable, not only imparting valuable techniques but also emphasizing the importance of respect and character development. My son, along with the other students, thoroughly enjoys the class and greatly benefits from the coaches' guidance.

New to BJJ? Start at Velez Jiujitsu

Velez Jiujitsu 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 Velez Jiujitsu

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.
