From the reviews

I’ve been training at Gorilla for 5 years now and I’ve loved every moment of it. Instructor Mike Wilson has a passion for BJJ and teaches virtually every class. His attention to detail and easy to understand analogies help make complicated technique easier to learn.

★★★★★ — Rory, Jan 2024

Great gym great people. My cousin switched to this gym a couple months ago and his game has dramatically improved since! Head Professor Mike runs a great program and everyone there rolls very respectfully. If you’re thinking about starting bjj or any type of striking, this is a great place to get started.

★★★★★ — Alex, Mar 2026

I have been going to gorilla BJJ for a year now and it is an amazing place. It is a nice big open mat and a smaller mat in front. The people there are nice and helpful. They explain thing extremely well and they keep the amazingly clean and a healthy working environment.

★★★★★ — Maddy, Dec 2020

Gorilla BJJ is a breath of fresh air if you're looking for a jiu-jitsu gym that breaks away from traditional formalities. Forget the bowing and the formal titles like "Professor" or "Sensei” here, they keep it wonderfully simple: technique, training, and fun!

New to BJJ? Start at Gorilla BJJ Academy

Gorilla BJJ Academy 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 Gorilla BJJ Academy

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.
