Great instructors, great music, and an environment without judgment. They have patience with both the young and old. If you feel intimidated about going to the gym their classes can always be modified (instructors will guide you.) Both Kickboxing and cross fit classes have both beginners and experienced. All their classes are top notch!!

Best gym around! I joined Fusion in October of 2019 and I have never been happier! For the first time in my life, I am very confident that I will have the body I always dreamed of. The coaches here are absolutely amazing! They push me to my limits every single class. I have never in my life received results so fast. If you are looking for a gym to push you and teach you how to eat healthy and workout as much as possible, Fusion is the place to go. The coaches truly care about your health, ( they don't try to sell you merchandise, health foods, etc. like other gyms that I have been to in the past). They send me weekly health newsletters and if I ever have a question all I do is message one of my coaches and I receive an instant response. My teammates are are all so welcoming and we all kick butt together like a family. I am never leaving!! Fusion is literally the "Best gym around"!!

Trained here for Two years had the time of my life great coaches that put time and effort into you and help you develop as a fighter. The people you train with always push you to be better. Best gym around.

I’ve been going to Fusion for a few weeks now and it’s been the best experience. I was nervous to go but everyone has made me feel totally comfortable. My trainer Tammy is awesome and pushes me to be more confident. It’s been great physically and mentally and so worth it, I wish I went sooner. 10/10 recommend!

This is not just a gym, it’s a family of AMAZING trainers that care about and love their career + their clients. But it goes beyond just a career, if you join this gym you will become part of the fusion family, soooooo much more than just a regular gym membership, this is a family that not only cares but transforms your body 💕

Last year, I made a New Year's resolution to get back into shape, and decided to REALLY stick with it, with the help of Fusion. I not only lost weight and have kept it off, but my endurance has improved, I have more energy than ever before, and am actually excited to work out for the first time in my life. It's all thanks to the classes here and the support of the awesome trainers. I was never into group fitness classes before coming here, and I will probably never go anywhere else. While the workouts are tough (a mix of cardio, strength training, bodyweight moves and core), it's a completely non-intimidating environment with highly knowledgeable trainers who can modify moves for first-timers (in every class, you'll find both regulars and beginners of all ages). Each class is different, so you never get bored with it, and the trainers are approachable and always willing to answer any questions you may have about diet, training, etc. I love the physical improvements I've made, but it's also been rewarding to really FEEL my own progress, challenge myself with each class, and to realize that I'm capable of achieving more than I thought I could. I look forward to my workouts at Fusion and hate missing a day. This place has changed my life and I am grateful!

The classes at Fusion are always super challenging and fun, and the trainers are really there to push you and help you reach your fullest potential. Whether it's kickboxing or X-training, I ALWAYS know I am going to get a great workout. Fusion has really helped me stay motivated.

Simply. The. Best. Each trainer offers something a little different to help create an overall incredible experience. The staff is kind, knowledge, and awesome all around. Fusion is way more than a gym, it's a family. There is constantly positive vibes and good people to surround yourself with. If you want a killer work out and pups to snuggle, come to Fusion.

Fantastic MMA gym. I was looking for a place that was not too "Cobra Kai" but had serious training. They let you go at your own pace or push you if you want. Inclusive is the best word. I am down 50 lbs, look and feel great.

I have been a member of Fusion for about 3 and a half years and absolutely love it! I have joined a handful of gyms before but never stuck to them. This is the first time that I have truly enjoyed exercising and I have finally been able to turn my health around and to get into better shape. All of the coaches are very encouraging to help you reach your fitness goals. Couldn't be happier.

The best gym and MMA program in Port Jefferson Station! The owners, the coaches and the members all create an environment where you will feel confident in yourself. At Fusion, you can attain your fitness goals without feeling pressured or rushed. There is tremendous love and support from everyone at Fusion! The big name brand gyms on Long Island all lack what Fusion has; quality services and documented results. Look no further because this is the gym you want to join.

Fusion is amazing! I am in the best shape of my life and love working out here. The coaches motivate and inspire me to challenge myself at every class. I’ve met some great people here and formed some great friendships. It’s the best! I highly recommend this gym.

Just started, but really enjoying it so far. Great instructors, great teaching methods without being overly aggressive, and fair pricing. Highly recommended.

I’ve only taken one class at Fusion so far but I’m loving it. The owners are super friendly, as well as the coaches I’ve met. Having so many things available in one place really caters to a lot of peoples interests, and is the main reason I’m choosing Fusion.

I’m a couple weeks into my training and so far I’m very happy. I’m a little older so training is pretty humbling to say the least haha but there are no hot heads here and all the trainers I’ve met are super professional and know what they’re doing.

I absolutely love training at Fusion. I try and go there every chance I get. The staff there is so accommodating, friendly and know exactly what they are talking about. They don’t just talk the talk, they walk the walk. I especially appreciate the head coaches Joe and Andre, they are incredible mentors. I can whole heartedly say that I have found the perfect place for my training needs.

Fusion is an mma gym unlike the others. From yoga to various combat sports; the trainers are attentive, and engaged; the kids trainers Jayme, and Joey, are excellent, and work with the kids building their confidence. As an experienced fighter, they capture the spirit of the discipline, with the form and functionality to appeal to kids and adults alike; I now understand why this gym has such a following and fantastic reviews.

Fusion is an amazing gym and a great welcoming atmosphere regardless of skill level. All the instructors are really cool dudes and every class is a ton of fun. Would never wanna train anywhere else.

Awesome group! A great, charismatic environment! The energy is really welcoming and comfortable. As a beginner to jujitsu, the group at Fusion made me feel really welcomed and comfortable training and learning new techniques. Joe and Andre are awesome, and theyve created a really great community and family at Fusion.

The people here are what make it great! You won’t regret signing up and working with these folks!

When I first started, my nervousness immediately washed away when realizing it’s sort of just a solo self-training program, so I had nothing to worry about when people are simply keeping their eyes in their own punching bag. There’s also the fact that everything is provided as a community resource (gloves, jump ropes, mats, etc) it was all really pleasant! I had nothing to worry about and fit right in ^^

This review got long so TL/DL: this place is amazing and both the instructors and students are great training partners and great people. I live/train/teach in Taiwan, but I'm back in town visiting family once a year. From the first time I messaged Joe, I could tell this would be an awesome place to train. Lucky enough to have been here several times last year and this year and here are some of my favorite things about their BJJ program. First of all, the environment here is absolutely the friendliest I've ever seen at a BJJ school, and that's saying something as most are very friendly places to begin with. I was treated like an old friend by everyone, from Joe and T (the Black Belt instructors), to all of the other students. I look forward to meeting new people here every time I head in, and always leave feeling like it's a really special place to train. Second, the instruction. Joe takes time to explain not only the techniques he teaches (which have all been both incredibly useful, but also simple enough even for me to understand haha), but also the broader philosophies behind both the techniques, and the positions from which they're applied. This means that students are not simply learning a single technique, but also getting more comfortable and familiar with many different positions that they'll encounter while rolling. Third, the other students. I've already mentioned that they are all incredibly friendly and welcoming, but in addition to that, they're incredibly tough and fun to roll with. No easy outs at this school; everyone has incredibly solid fundamentals and there are a lot of really advanced players here both in gi and no-gi classes. However, everyone still keeps safety in mind. As a visitor, it's important to keep myself protected while in the land of unaffordable health care, so I always try to tap early etc, but I haven't seen anyone be overly aggressive while going for a submission, and any time people are in leg entanglements, we all keep our partners' safety as our top priority. Lastly, there is a HUGE mat space available. Tons of people show up to evening classes but there's plenty of room for all of us to roll without constantly worrying about someone falling on you or anything like that. Can't recommend this place enough, and I consider myself lucky to have it nearby when I'm visiting NY!

I've been training at Fusion for almost 2 years now and I absolutely love it! I still leave each kickboxing class dripping sweat and have an incredible workout each time. All the coaches are so nice and welcoming, made me feel really comfortable coming to each class! I highly recommend them to anyone wanting to try out a class!

After trying out various other schools for training my daughter, this is the one that stood out from all of the others. This school is awesome and the instructors are talented and caring. I highly reccomend!

Coach Jayme is great. My son enjoys going to each training and cannot wait for next one. Owner Joe is very helpful and responded to my message quickly even during weekends. Lucky to have Fusion MMA in my neighborhood.

This place is amazing! Instructors make you work and sweat which I like. Place is welcoming to those that are new or experienced. I’d definitely recommend if you’re looking to get an amazing workout or just release stress from the week!

Fusion Kickboxing…A1 core, cardio & heavy bag workout that keeps you moving. Instructors are great, know how to motivate with the right amount of intensity while reading when to take the foot off the pedal giving you the right amount of rest just to explode back into the intensity. Highly recommended 1 hour class. I look forward to each workout.

I've trained here for just over 2 and a half years and it's been great. Getting here from coram is always quick and let's me make a lot of the classes. They have a good mix of classes that cater to fighters, casual martial artists who just want to train and even people who never want to fight and just want to get in shape. The environment is great there's not a lot of ego on the mats and the people are very friendly. The coaches especially are great, they'll stay after hours to talk to or help anyone who's serious about their goals. It's a great environment to learn and get in shape.

Fusion is a very supportive, welcoming, and inclusive gym! Now while I haven’t had too much experience with MMA training outside this gym, I do feel like all the coaches that I’ve met are very knowledgeable and efficient in the training methods. After a few weeks of training I can slowly see my confidence and skills grow but there’s much more to learn. The class attendees have also been very kind and patient with newcomers like myself. I’m excited to continue training and build my MMA skills. I highly recommend this gym for anyone looking to start or continue their training.

The atmosphere at fusion is awesome! Great instructors, classes can be for any fitness level. I joined with no prior kickboxing experience and integrated right into the workouts. The workouts are challenging and not boring! The yoga classes are the perfect recoveries you need for the week. They have a free weights section you are able to use before or after class with your membership. Would highly recommend !

Coaches are super cool and friendly. Love the community, lots of hard workers and nice people. You learn a lot and the coaches adjust to your experience levels. The memberships are a very good deal for how many classes you can get access to.

Love training at Fusion and the people there! It's a great place to meet your fitness and training goals. There's a good culture in the gym. It really feels like a second home 🔥

I've had a great experience training here for the past 3.5 years. There are many classes offered and the coaches are very knowledgeable and willing to help you reach your goals whether you want to be a fighter or to get in shape. I would recommend this to anyone in the area interested in fitness and martial arts.
