From the reviews
I've been training with Professor Nick for about 4-5 years now and I have nothing bad to say about him. Under his tutelage I have became a better Jiu Jitsu practitioner and a better a person. I owe a lot of my MMA and Jiu Jitsu success to this man right here.
I’ve had the privilege of training under Professor Nick since 2019, shortly after he moved up from Fight Sports Miami and brought truly world-class jiu-jitsu to our academy.
Around 3 years ago, I started training with Nick. Right off the bat I knew he was the real deal. Very well rounded and has a deep as well as admirable understanding of jiu jitsu. He brings positive energy and good vibes to every class.
Nick is an absolutely amazing teacher and outstanding individual off the mat as well. Whether you're a 40 year old hobbyist, a 20 yr old hard core competitor or anything in between, he's the guy you want in your corner. He similarly has outstanding kids classes.
New to BJJ? Start at Smash Flow Jiu Jitsu
Smash Flow 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 Smash Flow 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 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.
