WHAT STUDENTS ARE SAYING
⭐⭐⭐⭐⭐ At Big Mike's, you are joining a tribe of like-minded practitioners that are grounded in respect for BJJ as a martial art, and respect for the safe and effective development of one another. Professor Gorski is a high quality instructor, coach, and mentor that is genuinely invested in his students.
⭐⭐⭐⭐⭐ Awesome guy! Great safe learning and tons of knowledge!
⭐⭐⭐⭐⭐ Mike is a great guy and coach. His method towards fundamentals has been really great and the environment is very much family oriented. If your looking to begin BJJ or have been training for awhile and looking for a new gym, this is the spot for you!
⭐⭐⭐⭐⭐ I started training with Mike for self defense purposes which then turned into me still attending a year later. As a woman joining a male dominate sport it can feel intimidating to say the least, but Mike and everyone there is extremely welcoming, professional and safe. It’s a great environment for someone just getting into the sport, drop ins, as well as the lifers. If you’ve thought about trying BJJ it’s worth stopping by and checking out the class. It doesn’t take long to get hooked and Mike makes you feel at home and comfortable right away. Come on girls!
⭐⭐⭐⭐⭐ Big Mike's BJJ is very welcoming and a great place to get a good workout and learn self-defence. I've always been athletic, but I'm not much of a gym goer or weight lifter and was looking for a way to improve my strength and cardio...BJJ was definitely it! Been here for a year and loving it.
⭐⭐⭐⭐⭐ Great facility and great people! The instructor provides a standardized way to learn for all levels and ages.
⭐⭐⭐⭐⭐ I cannot recommend Big Mike's BJJ enough. I've enjoyed every minute that I've got to spend learning about this sport from Mike. Not only has the instruction been excellent but the people that you also get to work with learning this sport that attend his gym are also great to work with. I work in the evening and attend this class before going to work and I feel like I am more energetic and more focused after going to class then I normally would without it. This is the most fun workout that I have ever done. At my age I was looking for something that was going to be a good workout but also not put me at risk of hurting myself and so far I would say that this is easily the best workout choice I have ever made. After 2 months I am healthier and stronger than I have been in years.
⭐⭐⭐⭐⭐ Big Mikes has a familial vibe, which is what jiu jitsu is all about. There’s a welcoming atmosphere that immediately made us want to train there. Mike also has great patience with the kid’s classes. I also enjoy there is a curriculum to learn and videos to go over material when you’re not in class. That is very helpful in retaining the information. We’re so glad we found Big Mikes!
⭐⭐⭐⭐⭐ We have been going to Big Mikes BJJ for over a year and a half now and the growth has been phenomenal in my child. Big Mike is friendly and makes training fun all while teaching discipline. I highly recommend Big Mike BJJ to anyone and everyone who is interested in jiu-jitsu.
⭐⭐⭐⭐⭐ My son has been going to Big Mike's for a little over a year now.
The commarodary, discipline, and confidence he's gaining and developing is showing in him.
Big Mike is amazing with the kids.
I also have attended his adult class on occasion, and it's a really welcoming environment.
The guys and gals I've met there on the mats are some of the coolest people I've met.
Go give Big Mike's a try.
You won't regret it!

⭐⭐⭐⭐⭐ Mike's gym is AMAZING! The environment he has is a dedicated learning environment for beginners and experienced students.
When I first started, I came from a background of zero knowledge and was nervous my first time in class. Now I'm dedicated to BJJ because of his education based curriculum.
If your even thinking about starting BJJ, try out his class and you will be glad you did. And the first class was FREE so I had nothing to lose.
I found myself to be a life long student of his and won't be going anywhere else!
⭐⭐⭐⭐⭐ Was in Oak Harbor for a month due to some job training, so I decided to try my hand at BJJ because I missed my wrestling days back in high school.
The staff here are incredibly polite, professional and helpful. If you want some good exercise along with a new and fun skill to learn, check them out! You will not be disappointed.
⭐⭐⭐⭐⭐ If you want a jiu-jitsu class where you can learn, grow, and make friends, I highly recommend Big Mike's BJJ. I've been training there for two years, and it's been fantastic. The atmosphere is friendly, and I've met some great people who share my passion for jiu-jitsu. Mike’s teaching is clear, effective, and he always puts safety first. I’ll miss him and everyone at gym!
⭐⭐⭐⭐⭐ Mike is like the awesome dad you never had. However, instead of getting that hug you have always wanted, you’re left smiling the whole time while you get triangle choked. Truly though, Mike is an all-around patient, thoughtful, and honest person. He has created a school with an atmosphere that is like being a part of a family. He brings his passion and extensive knowledge with him to teach each day whether it is with child classes, adult classes, complete beginners or season practitioners. Big Mike’s Bjj is for everyone

⭐⭐⭐⭐⭐ Great prices, instruction and atmosphere!
⭐⭐⭐⭐⭐ Great place! Mike's teaching is very clear and enthusiastic, and it was easy to feel a part of the group after even one week. I wholeheartedly recommend!
⭐⭐⭐⭐⭐ Top notch instruction for all ages and experience levels. Also, Big Mike doesn't employ money-grabbing gimmicks like forcing you to pay for testing/advancement or "volunteer" at school-sponsored events. Very good value for the money and time investment. Highly recommend the free trial.
⭐⭐⭐⭐⭐ Joining Big Mikes BJJ has changed my life for the better, Mikes way of teaching is so understandable. This Gym is very welcoming to all walks of life. Glad to be apart of this Family.
⭐⭐⭐⭐⭐ Big Mike’s BJJ is a great place to start learning, and continue to grow your skills in BJJ. Big Mike is a very patient and thorough instructor that deeply cares about the culture he fosters in the gym. He hones in to each individual’s learning skills and ensures moves are done correctly. Its been a great experience and keeps everyone wanting to come back for more!
⭐⭐⭐⭐⭐ My son and I joined somewhat recently. He is loving it. I want to say awesome our experience has been so far. I never thought I'd feel so good about getting twisted up like a pretzel but it is a blast. It really does seem like a special sport with an awesome, welcoming community. I realize I haven't even scratched the surface yet but thought I'd give my two cents. If you're on the fence about it, go for it. You will be welcomed and treated well.
⭐⭐⭐⭐⭐ Mike is awesome! He is very patient with my child and teaches him valuable skills to use in life and gives him an additional male role model while I am deployed. He has grown so much as a little man and I am planning to join for myself soon! Thanks Mike!
⭐⭐⭐⭐⭐ Big Mike’s BJJ is an amazing place for kids where they learn discipline, safety and best of all, practice self defense knowledge in a great environment.
⭐⭐⭐⭐⭐ My 8 year old son loves coming to this facility. Very hands on and educational. Classes are Monday through Thursday. We’ve been going here for roughly 7 months. It was such a great decision!
⭐⭐⭐⭐⭐ We love this studio. This is more than just a place to learn jiujitsu—it's a community that fosters growth, confidence, and respect in a welcoming environment.
The culture here is amazing for both girls and boys, women and men, creating a safe and supportive space where everyone feels valued. There truly is a sense of community we feel through the connections made at this studio.
The coaches are exceptional, balancing discipline and encouragement perfectly. They not only teach the techniques and skills of jiujitsu but also life lessons that will carry through into adulthood.
One of the standout aspects is how they address important topics like bullying, giving kids the tools and confidence to handle conflicts with others—and even within themselves. The training helps calm the ego, release stress, and develop a strong sense of self-discipline.
It's clear that Coach Mike values more than just physical training; he is dedicated to shaping well-rounded individuals who learn respect for themselves and others. If you're looking for a studio that will make a positive impact on your life, this is the place!
⭐⭐⭐⭐⭐ My kids have been going to Big Mike’s for two years now. We love it. Mike is so patient with the kids and takes time to make sure they know the basics and core moves.
⭐⭐⭐⭐⭐ Every time my son gets done with class, he turns to me and says, "that was fun mom". He likes to talk about his thoughts on how class went, what he did or could do differently next time! He loves it!!! Mike is an awesome instructor. Very grateful for this new adventure for my son and grateful he landed here!
⭐⭐⭐⭐⭐ Im just now beginning my BJJ training at 39 and I absolutely love Mike's programming and claa structure. He has a foundations class that teaches need to know skills in a way that builds confidence and really helps.you practice technique over intensity. Whether you need practice to improve your game or starting out, it's perfect for a beginner like me or even more advanced athletes. The community is very welcoming and helpful. Big Mike's is the best!!!
⭐⭐⭐⭐⭐ Great kids program and very military friendly. In just a mere six months, I noticed a huge difference in my daughters’ behavior and they would even look forward to attending class. Additionally, Coach Mike is very knowledgeable and demonstrates the perfect amount of patience when dealing with kids. His highest priority was always predicated on safety, definitely putting my wife and I at ease when we first enrolled my daughters. I had previously enrolled my daughters in tae kwon do, and no knock on them at all, but the level of growth my daughters experienced under Coach Mike, was leaps and bounds higher than the full year in half they did in Tae Kwon Do. If I ever get stationed here in Oak Harbor again, I will undoubtedly be enrolling my kids again with Coach Mike. BEST BJJ GYM IN OAK HARBOR HANDS DOWN!
⭐⭐⭐⭐⭐ Big Mike has been an incredible influence on my son—not just in jiu jitsu, but in discipline, confidence, and mainly focus. His ability to teach technique while still making every class fun and encouraging is rare. We're lucky to have such a dedicated and positive role model in our community.
⭐⭐⭐⭐⭐ I've been training at Big Mike's Jiu-Jitsu Gym for the past year, and it's hands down the best gym I've ever been to. The sense of community here is unmatched, making it not only a fantastic place to train but also an excellent environment to get back in shape. Since I started, I've lost over 30 pounds! I highly recommend Big Mike's to anyone looking to improve their fitness and be part of a supportive community.
⭐⭐⭐⭐⭐ What a cool place. Big Mike is fantastic, just got out of a really fun first session.
⭐⭐⭐⭐⭐ We love Big Mikes BJJ! Love the small classes for more focused instruction. Mike is excellent with the kids!
⭐⭐⭐⭐⭐ Outstanding BJJ Academy — Feels Like Home
I recently had the pleasure of dropping into Big Mike’s BJJ Academy while traveling for military duty, and I couldn’t have asked for a better experience. From the moment I walked in, Big Mike and all the students welcomed me with open arms and some solid rolls. The atmosphere was friendly, respectful, and focused — a perfect balance of serious training and genuine camaraderie.
Whether you're looking for a home gym or just passing through, Big Mike’s is the kind of academy that makes you feel like part of the team on day one. Highly recommend to anyone in the area or visiting — you won’t regret it!

FREQUENTLY ASKED QUESTIONS
Check out the most frequently asked questions about Big Mike's BJJ.
Still haven't found the answer?
Contact UsAre parents allowed to watch?
We encourage parents to stay and watch their children during class. We’ve found that when parents watch, kids feel supported and encouraged, which can enhance their focus and enjoyment during class.
We love when parents get involved! Even better, you can join our adult program and have yet another thing in common with your kids.
Will my child become a bully?
Our experience has shown that confident kids make kinder kids. We teach children not only how to stand up to bullies for themselves but also how to stand up for others.
We emphasize avoiding fights by first using words and then telling an adult. If physical self-defense becomes necessary, we teach grappling holds to neutralize and control, never punches or kicks.
Do I need to be fit or athletic to be able to do this?
There are zero fitness requirements to start our beginner Brazilian Jiu-Jitsu classes!
BJJ emphasizes using leverage, timing, and precision, making it effective for people of all fitness levels without relying on brute strength.
While many other martial arts claim to teach you how to use leverage to beat strength, timing to beat speed, and precision to beat power, BJJ truly delivers. Our students start at all different fitness levels, and you’ll find that you naturally improve your fitness by practicing Jiu-Jitsu.
What if I’m not very sporty or coordinated?
No worries. In fact, many students starting in our adult martial arts classes feel the exact same way.
Give yourself some time, and you’ll be astounded at what your body is capable of and how much you can improve! Our Foundations classes are perfect for beginners like you, so even the most uncoordinated person will develop ‘ninja-like’ skills in due time.
Join us for a class, and you’ll see how much you’re capable of—it’s all about building skills step by step in a supportive environment.
Karate classes vs. BJJ classes—Which is better?
While we believe all martial arts have value, Brazilian Jiu-Jitsu offers unique benefits that make it stand out.
For nearly a century, BJJ has been proven as the most effective martial art for a smaller person to defend themselves in a real fight. Unlike karate or taekwondo, which focus on striking, BJJ prioritizes neutralizing a threat by clinching the opponent, taking the fight to the ground, and controlling the situation. It’s effective, gentle, and scalable, allowing you to de-escalate without causing harm.
What do I need to bring to my first martial arts lesson?
It’s easy to get started. No special equipment is needed! Wear comfortable clothes like loose-fitting sweatpants and a t-shirt. Bring a water bottle to stay hydrated and flip-flops to wear when you’re off the mats. Come ready to have fun and work up a sweat!
How do I get started?
We’d love to have you join our BJJ family! We only have a certain amount of space in our training area, so we’ve developed a waitlist from time to time in the past.
To get in while we still have space, the fastest way is to click here to book a free class and secure your spot today.
