The right BJJ instructor explains why a technique works, adapts it to your body, and tracks what you need to fix — belt level alone doesn't tell you that. Book one private session and pay attention to how they teach, not just what rank they hold, before committing to more.
Why the Instructor Matters More Than the Gym
The gym you pick matters less than who's actually teaching you. Mat quality, location, the schedule board on the wall — none of it moves your jiu-jitsu forward if the person correcting you can't correct you well. That's true everywhere in Brooklyn, and it's true double in a private lesson, where there's no group dynamic to hide a weak explanation.
In a one-on-one session it's just you and the instructor for the hour. There's no curriculum to coast through and no other student to watch instead of you. Either the instructor knows how to break down a position and fix what's actually wrong with your version of it, or they don't. You find out inside one session, not six months in.
Belt Level Isn't the Same Thing as Teaching Ability
A high belt who demonstrates and expects you to absorb it by watching will teach you less than someone lower ranked who can actually explain the mechanics. Competing well and teaching well are different skills, and BJJ has plenty of people who are excellent at one and shaky at the other.
A few things worth checking in an actual session:
- Can they tell you why a detail matters, not just show you the motion again? If you ask why your hand goes there in a pass and the answer is a shrug or a repeat of the demo, that's a gap.
- Do they account for your body? A technique that works cleanly for a bigger, longer-limbed person sometimes needs a real adjustment for someone smaller. An instructor who never mentions this isn't watching you specifically.
- Do they remember what they worked on with you last time? Private lessons are supposed to build across sessions. If every session starts from zero, you're not getting the benefit of it being one-on-one.
Does Lineage Actually Matter?
Yes, lineage matters in BJJ more than in most sports, because it shapes how someone was taught fundamentals in the first place — not just who they can name-drop. I'm a purple belt under Eugene Sakirski, a black belt under Renzo Gracie, and Eugene has spent roughly three decades on the mat. That background is where the instruction I give in a private actually comes from.
When you're checking out an instructor, ask where they trained and under whom. A instructor who answers that clearly and can talk about how it shaped their approach to fundamentals is a good sign. One who gets vague about it is worth a second look. You can read more about how I approach one-on-one instruction on the private lessons page.
Red Flags to Watch For
A few patterns are worth walking away from, and most of them show up in the first session if you're paying attention.
- They can't explain why a technique works — only that it does. Understanding the mechanical principle is what lets you adapt a technique to your own game later. If they can't explain it, they're teaching you a memorized motion, not a concept.
- They skip fundamentals for flashy positions. Leg locks and modern guard work have their place, but if you ask about escaping side control and they'd rather show you something advanced, the priorities are backwards for a beginner or even most intermediates.
- They're not watching you. Sounds obvious. In a private lesson you're paying for someone's full attention for an hour. If they're distracted, that hour isn't doing what it should.
Questions Worth Asking Before You Book
Ask these before committing to a series of sessions with anyone, not just me:
- What does a typical private lesson with you look like?
- How do you decide what to work on for a given session?
- Who did you train under, and what's the lineage?
- Can gi and no-gi both be worked into the sessions, or is it one or the other?
A private lesson lets an instructor tailor the hour to what you actually need, whether that's cleaning up guard retention, working takedowns and wrestling fundamentals for BJJ, or just getting through your first few months without bad habits. I go into more of that structure in this post on private lessons for beginners and intermediates.

I don't run group classes or kids' classes, and there's no MMA or striking on the schedule. It's private lessons only, for beginners through competitors, with wrestling and submission grappling fundamentals worked into the session when it's useful.
Pricing is flat and simple: $100 for a solo hour, or $50 per person if a training partner splits the session with you. No packages, no bundles, just the session you book. Hours run mornings on weekdays and midday to afternoon on weekends — exact openings are on the booking calendar.
Not the same school as Cobble Hill BJJ
Search engines sometimes mix these up. I'm not affiliated with Cobble Hill BJJ — I teach privates at Darfight Martial Arts in Brighton Beach.
How to Actually Evaluate Someone Before You Commit
The fastest way to know if an instructor is right for you is to book one session and pay attention to how they teach, not just what belt they wear. Watch whether they explain the why behind a detail, whether they adjust for your body and experience level, and whether they're actually watching your reps instead of just running through a checklist. One honest hour tells you more than any bio page.
Book a Private and See for Yourself
If you want to try a private lesson and judge the instruction firsthand, the booking calendar is open with current time slots. Reviews from past students are up on Google if you want another data point before you book.

Questions people ask
Does a higher belt automatically mean better instruction?
No. Competing well and teaching well are different skills. Some lower belts who've spent real time coaching beginners explain mechanics more clearly than a higher belt who's used to just demonstrating and expecting you to absorb it.
Why does lineage matter in BJJ?
Lineage shapes how someone was taught fundamentals and what emphasis got passed down to them. It's not just a credential — it affects the instructor's approach to mechanics, not only their resume.
Can I try a single private lesson before committing to more?
Yes, sessions are booked one at a time with flat per-session pricing, so there's no package to commit to upfront. You can book through the booking calendar and decide session by session.
What's the difference between a private lesson and group class for evaluating an instructor?
In a private lesson it's just you and the instructor for the hour, so their ability to explain and correct shows up immediately. In group class it's easier for weak instruction to hide behind the curriculum or the other students. More on that comparison is in this post on privates versus group classes.
