Good place, good teachers.

Sensei Jack is one of a kind. He does a great job engaging the kids to listen and truly learn. The things that Sensei teaches are life lessons and values, not just self defense/judo. He pushed the kids to be their best in a way the kids don’t even know. He truly is an amazing teacher! We love him. My daughter has been there for 2 years and loves it. We are looking forward to sending our son in the crawl program. Thank you for loving these kids as much as you do!

Sensei Jack is a rare gem. He combines his reverence for martial arts with philosophical ideology to help children make strong choices. He rewards effort not participation and helps the kids develop a sense of accountability with his gentle but firm direction. 10/10 I am so glad I found this place and drive from Long Island that’s how good it is!

Joining Krystek's has been a life-changing experience. From my first day, I felt welcome and supported by the instructors and students. The sense of community here is truly special. There is a strong camaraderie among students. We support and motivate each other, celebrating each other's successes and encouraging each other through setbacks. The instructors are experts who love the sport and are incredible mentors. They’ve guided my growth as a martial artist and as person. Training at Krystek improved my physical fitness, mental resilience, and confidence. I've learned to approach challenges with a positive and disciplined mindset and to persevere through the tough times. My son is enrolled in the kids' judo program. The class environment is safe, and the classes foster physical, emotional, and cognitive development. My son went from being shy and reserved to an expressive and active participant. Before starting Krystek’s, my son was placed in the adaptive physical education class. I firmly believe that Sensei Jack’s coaching brought about confidence and strength to rejoin the general ed class. If you're looking for a dojo that offers top-notch training, a supportive community, and a transformative experience, I wholeheartedly recommend Krystek School of Judo, BJJ, Self Defense & Fitness. It's a place where you can grow, learn, and become the best version of yourself.

This dojo is truly like a home and creates an amazing sense of community among both the adult and junior classes. Sensei Jack Sr. and Sensei Jack Jr. are both attentive to their students developments not only on the mat but also in real world scenarios to give every student a sense of self-confidence. Coming here has been a blast and it’s something I always look forward to!

Very good school ! My son loves Sensai Jack !

This place is the best. I've been training there for over 10 years and now my kids train there. The senseis are terrific, patient and knowledgeable and you can really tell they absolutely love the sport and sharing that knowledge. It's more like a family than a school and nothing is more important than the students.

Krystek is amazing! Sensei is dedicated, caring, knowledgeable, and driven. He wants all of his students to reach their goals and beyond. He sees the best in everyone, and brings out the best in them. I’ve witnessed him working with 3 year olds to people in their 60s. His teaching style is flexible and dynamic. I can’t tell enough people to join the school and take all of his classes! He has changed my life and the lives of so many that I know!

This place is so special. The Krystek family created such a great learning environment for adults and children.

I've been a member of the school since 1992, and I can tell you both Jack Sr. & Jack Jr. have respectably serviced the community since the 1960's. As a student for over 25 years the respect, honesty and dedication the family has towards all the students is very rarely found at this level. They teach adults and children as young as 4 years old not only about martial arts but about creating a better person. I can truly state I would not be where I am today if not for the many years of education at this establishment. One of the great aspects of the school is the work both Sr. and Jr. put in with the children, they are very hands on with the classes. They are more than willing to work individually with everyone, unlike most martial arts schools you are made to feel comfortable and at home. They treat ALL members like family with a dedicated approach to hard work and constructive learning. No matter your skill level they are able to bring out the best in your ability. Actually the most important thing in all of this is it's FUN to be apart of, you want to go to class and continue improving. Take notice of the variety in class types from self defense to cardio based. Highly recommend to anyone.

Nowhere else better to train. Sensei Jack , Jack Jr, and Frank are the most friendly approachable, knowledgeable, and uplifting people. Any time you have a bad day and come here after is an automatic mood changer. No matter your athletic talent, physical shape, and goals, this is the place for you. Learning from one the of best and experienced judokas in the world always helps. No matter what your goal is, coming here will make you a better person in the physical and mental form. Highly recommended, and you will not be disapointed.

Really welcoming environment. Great place for all ages to train and learn, no matter the skill level. So blessed to have been referred here. My 9 yr old son and I love training in Judo and BJJ under Sensei Jack.
