Testimonials
“I have been training at the Judo Karate Center for over 30 years. The instructors are very knowledgeable, friendly, and patient. They teach judo in a safe and respectful environment. The classes are challenging but also enjoyable. If you want to learn Judo the right way, check out the Judo Karate Center , it is more than just a dojo, it’s a family. I highly recommend it to anyone who wants to learn martial arts or just have a good time.”
“Sensei Nick is an incredible teacher and the club is made up of knowledgable and talented students that make for amazing training partners! The club itself has a rich history that you feel as soon as you walk through the door. I have been training here for over 2.5 years now, and it has been a place that I have developed as an individual and made friends in addition to learning judo from people at the highest level. This is a really special place that I cannot recommend highly enough!”
“Cranford Judo has become like a second home to me. The level of instruction is excellent, but what really stands out is the culture — everyone trains hard while still looking out for each other. The coaches are knowledgeable, patient, and passionate about teaching real judo. Every class pushes me to improve mentally and physically, and the randori is competitive but respectful. I’ve learned a lot from training with higher belts and experienced judoka who are always willing to help. If you’re looking to cross train or just to learn Judo this is the place to be.”
