My family & I are extremely grateful to have found LI Ninjutsu. The staff are motivating, extremely welcoming & supportive and provide great guidance to our 2 year old son. We have found significant improvements in his ability to transition, impulse control & emotional regulation. He is becoming stronger and smarter after each session. He loves going to the dojo and is motivated by their reward system. He also loves the playground out back. We look forward to watching him progress and grow with the staff at LI Ninjutsu!

My daughter has been attending Ninjutsu for two months now. From the moment we walked into Ninjutsu, we felt like family. Shihan Allie and Renshi Ryan are so friendly, so kind, and so patient. It all started when I saw Shihan Allie disciplining a young student... he did not yell, he did not scream... he did not appear to be angry... instead he was calm, he was reasonable, and he was stern and somehow his tactics worked. I knew this was exactly what my daughter needed. I couldn't be happier with my decision to sign up. My daughter asks every day "can we go now?" I look forward to watching my daughter grow and develop the self confidence and discipline that she needs!

L.I. Ninjutsu Centers has been a mainstay of the community for decades. I studied there as a teen and was so excited to bring my son there now. They still have the same focus on discipline, respect, and tradition. You aren't just learning the punching and kicking, you are learning the art of the Ninja and beyond. I can't speak highly enough about them. They build confidence through EARNING each promotion. All of the values I want to instill in my son.

Our son John has been apart of this Ninjutsu FAMILY since he is 4 years old...now almost 11 years old and still loves every class! John was timid, shy and unfocused. He is now known as Mayor John, he is outgoing, confident, uses words before hands, respectful, honest and I truly believe this began at this dojo. Shihan Allie and Renshi Ryan are extremely knowledgeable, encouraging and provide a safe, welcoming training atmosphere that is carried into John's everyday activities... school, baseball, wrestling, football, family, friends... his foundation in Ninjutsu has helped him in all of these areas! John's focus is better, he is mentally and physically challenged. This is not just kicking and punching... self defense is wonderful but the power of everything you get is authentic.

LI Ninjutsu Centers has been so beneficial for my kids. At first I enrolled them to increase their agility and balance and we got so much more back. Their confidence, ambition, and discipline have all improved and the support for their well-being and aspirations is all so noticeable. You can get as involved as you like at the dojo, and mine chose to compete in tournaments and were accepted onto the demo team which makes them feel more connected to the martial arts family here and enhance their sense of pride. I always recommend this dojo to my friends.

It was very hard finding something to motivate my daughter, and this place sparked her drive from the beginning. We did a trial at two ninja schools and she really enjoyed her time during the free trial. She can have some social anxiety and low confidence and everyone was so patient and positive with her! The outreach of information to families is top notch, and the texts checking in if they haven’t seen us in a while shows how much they care. She even got a personalized video welcoming her and it really made her feel great. We have been a part of multiple martial arts schools over the years and this one really takes the cake. It’s affordable and everyone really cares about the students and learning.

My son has been at L.I. Ninjutsu Centers of East Islip for 3 years, and it’s been amazing! The instructors are awesome — super supportive and really care about the kids. He’s learned respect, responsibility, and made great friends along the way. In addition, he’s developed confidence that carries over into school and everyday life. The balance between discipline and fun makes this center stand out. It’s more than just martial arts — it’s a community that empowers kids to be their best selves. Couldn’t recommend this place more!

For those shopping around for a martial arts studio for their children, look no further!! We are so very happy with L.I. Ninjutsu Center. The option for a 2 week free trial is SO helpful for initial parent perspective. L.I. Ninjutsu Center is a very trustworthy and Reputable business. The owner and his staff are extremely detail oriented and very Informative. About every process and step along the way. The staff is very welcoming and helpful. They offer a convenient APP for booking classes, managing your account, and helpful resources. They have a great schedule of class options, and they constantly blast out emails, texts, notifications, and keep parents informed of every day happenings in the Dojo. The owner is passionate about his life’s work and training. He is kind, and proud to offer, not only martial arts training, but life skills, to our community/his patrons and clients. I Highly recommend L.I. Ninjutsu Center and I’m grateful to have found such a wonderful, local, spot for my son to learn the art of Ninjutsu.

I hardly ever review anything but during this negative time I had to point out the positive; being quarantined with a newborn and 5 yr old was rough emotionally and mentally, my son refused to do school work and did not want to train any longer... Shihan Allie reached out with a loving positive message that restored my son and I... as if that wasn’t enough he personally came to our home (following all 6ft apart rules) to deliver a care package! I was already so happy to have joined the Ninjutsu family but now we are 100% sure we are staying!!!

My daughter absolutely LOVES going to Ninjutsu. Every morning she asks to go again. Shihan Allie and Renshi Ryan have been amazing so far. They are extremely welcoming, kind, friendly and patient. We felt like family from the moment we walked in. I am looking forward to watching Bella grow and gain that self confidence and discipline that she needs.

I loved the attention to detail and the small corrections were made to my form and technique. I had a lot of fun with the weapons training.

I love this place. They teach beyond martial arts, they go into the philosophy of it. They show you patience, respect and discipline and inspire you to grow, and classes are always fun. The teachers are very real, and make you think outside the box. One thing I love the most is the energy, how nice every one is, you can tell they are a family. I felt welcome since the first day; I’m new and my class mates are quick to always help me and teach me if I’m lost in something.
