• He really is about his students and you will leave satisfied with your workout. The adult kickboxing classes are tough but the workouts are definitely efficient. This is a great place to have children learn martial arts with no gimmicks;  it is authentic and it all takes place in a beautiful, clean studio.

  • I’ve known Sensei John aka Johnny Karate most of my life. I have nothing but the best to say about him and the instructors/professors he employs. His classes from the Hyperfitness Club to Brazilian Jujitsu are always informative and humbling. They are always safe but safe doesn’t mean you won’t work hard. So get to class!  Hope to see you there!

  • The Johnny Karate program has changed the course of my kid’s behavior, discipline and outlook on life. One child needed to boost their confidence. The other child needed to learn to control their anger and body. I can’t say enough great things about this program! 

    I was so inspired by how much my kids learned I signed up for the adult kickboxing class myself. Perfect for all ages and fitness levels.

  • Can't praise this school enough. Our son has attended for over 4 years, learning  martial arts as much as life skills.  This is not a cookie cutter after school activity.  Sensei John works hard to makes sure every child feels welcome and included and he has a knack for individualizing the training experience to match a child's ability, age and temperament.

  • Sensai John has completely changed our lives. My son has been attending classes for several years now, it's amazing to watch the respect he has with Johnny but also his enjoyment and ability to be himself. He often gets into trouble in school but at Karate he's like a different kid. I highly recommend karate with Johnny Karate Martial Arts.

  • John is a true expert in his area. I have watched him work with adults and children alike with nothing but the utmost professionalism, passion, and charisma. His classes are energetic, varying levels, and overall a great time. John can tailor your experience to what you are looking to achieve whether it’s strength, weight loss, or personal development. Johnny Karate is a Brooklyn based business from the heart!

  • A great workout in an hour and half. Plenty of good tips and techniques for a beginner. I appreciated the time and attention from both instructors and can tell that they enjoy what they do.

  • It’s hard for me to commit to working out but I have started taking Jiu Jitsu. I love it, the instructor is amazing and really takes her time to ensure that you understand and are able to perform the moves to eventually perfect them. I have been coming here consistently on Mondays for a few weeks now and I want to continue. Such a friendly and great environment to get my workout in. I’m also thinking about joining the kickboxing classes that are offered here to not just come in on Mondays.

  • Top notch! Great instructors, fun, friendly, exciting, and effective classes for both adults and children. My lady and I take BJJ there, my son, the Karate. Couldn't give a higher recommendation. Incredible value. 5* all the way!

  • I come here for kickboxing and jujitsu and every class is a such a fun experience! I've learned so much taking these classes and feel as if they're great for people of all ages. I also love the environment of the studio and everyone is motivated to do their best!

  • I highly recommend Johnny Karate!! I have been bringing my daughter to Johnny for 3 years, from age 4. She started at another Martial Arts school before and the teaching at Johnny’s is far superior - more attention to proper form, technique, self discipline, self defense, all while keeping it fun for the kids! Classes are age and development appropriate and he moves the kids up slowly with their belt ranks so they are really learning and earning their belts. I have seen the older kids that he has been training for 7-8 years already, and they are really impressive. I look forward to my daughter reaching that level in a few years!

    Johnny is amazing! He doesn’t just teach the children, he really cares about them. They love to go and are not afraid to work hard because Johnny is such a great sensei! His unique style is not just a physical but a mental workout that promotes discipline and increased self esteem! We highly recommend!

    We have two kids who have been training with Johnny Karate for awhile now and they thoroughly enjoy the classes and the experience of learning martial arts with Johnny. The kids have an overwhelming feeling of accomplishment and satisfaction from the program and passing one level and moving to another level. And best of all, for us parents, the kids are pretty much tuckered and ready for bed after class.
