Our family has been training at JSK Taekwondo in Flemington for about a year and a half, and we’ve enjoyed it immensely. Master Jang and his staff run an excellent program — professional, encouraging, and full of positive energy. Both of our kids have developed a real enthusiasm for Taekwondo, and it’s been amazing to watch their confidence and skills grow. My wife and I have also seen great improvements in our fitness and coordination. Master Jang’s classes are just as beneficial for adults as they are for kids. We highly recommend JSK Taekwondo for anyone looking for a welcoming and inspiring martial arts school.

My 8yo girls started classes in the spring of 2023. Since then, I’ve personally observed (as well as heard from many others) how absolutely amazing Master Jang is as a TKD trainer. He genuinely cares for his students and has a unique way of balancing discipline with lighthearted humor. He makes each class productively fun, filled with physical and mental stimulation from start to finish. 11 belts later, my junior black belt girls still look forward to seeing Master Jang!

We highly recommend JSK! My son started off very shy and didn’t participate - Master Jang and his staff were all super supportive + kind to him and made him feel welcomed! I feel like these classes help build his day to day confidence tremendously!

Master Jang is awesome! My daughter loves going to tae kwon do every week! She never had interested until we went in and he made us feel so welcomed. My son originally wanted to do kwon do but my daughter after speaking with Master Jang decided to give it a go! She was so shy at first but really had come out of her shell! She has gained so much confidence, self discipline and respect just in a few short weeks! We are looking forward to adding another day and for when my son is ready to participate as well! Master Jang really loves his job and his Dojo! We are thrilled to have found him!

Master Jang is one of a kind. He immediately knows every child’s name and their personality. He makes each kid who walks through that door feel special and seen. His instructors reflect his values. Both my child have come a long way in a short period of time. They respect him like no other.

Would highly recommend JSK Taekwondo! Master Jang is an excellent teacher, and my son really enjoys learning from him. Being a very shy three year old, one day my son was too afraid to join the older children during class, so Master Jang offered to give him a private lesson the next day when the studio was closed. I was so grateful for Master Jang’s kindness, compassion, and flexibility in that moment.

Best Taekwondo school in the area. We switched our kids from a different school to JSK and we have noticed a big improvement in their skill and discipline. Master Jang is amazing with the kids. He is the perfect amount of fun and serious that keep the kids engaged and on track. I can't recommend this school enough.

My 5 year old has been at JSK for a year now. She has grown in so many ways, inside and outside of taekwondo. Master Jang and his team have supported her to become more confident, strong, flexible, and focused. Master Jang does a great job of building relationships with all of his students while teaching discipline and developing skills.

We also hosted my daughter's birthday party here and the party package was reasonable and every child had a great time, regardless of their familiarity with taekwondo. My daughter felt very special to share something she loves with her friends.

We absolutely love JSK! We had heard wonderful things about them and my daughter had been wanting to try Taekwondo so it seemed like a no brainer. Master Jang is the best! He has this innate ability to understand each child, build on their strength and helps them to learn confidence, respect, boundaries and more. I can't say enough wonderful things about them!

Master Jang at JSK is amazing! We enrolled our 3 year old son at JSK a little over a month ago and he has thrived! Master Jang is incredibly patient with children and runs a great class. We are so happy with his instruction and dedication. It's obvious that Master Jang has a true passion for his business and students. Our son loves his class and looks forward to it each and every time. We're so lucky to have this phenomenal place so close to home.

I'm not sure if there are words to explain how amazing JSK and Master Jang are. We began attending JSK just before the pandemic hit in March 2020. Throughout the pandemic, Master Jang FOUND ways to keep his students engaged until in person classes could be offered again. He talked to parents about what works best for our families. If we need help with scheduling, he always tries to accommodate so that the kids can train. When in person classes began, Master Jang was so organized and prepared to welcome us back in QUICKLY and SAFELY. The students were so happy and excited to be back. As a parent, when I enter the studio for belt promotions or classes or events, I can see that EVERY child has a relationship with Master Jang and Mr. Alex and the other instructors. Each child is an individual and special but also a member of the team. The students are supportive of each other and respectful. My son has grown so much since he has begun attending. He is more respectful at home, more independent, and to be honest, when he steps out of line, all I have to say is "I'm going to talk to Master Jang about this,"and he hops right back lol. There are other Taekwondo and martial arts studios closer to my home, but I would never consider going anywhere else. The drive is 100% worth it. Thank you Master Jang, Mr. Alex, and the rest of the JSK Team for ALL you do for our children.

I interviewed all the martial art schools in Hunterdon County NJ. By far best instructor was Master Jang at JSK Taekwondo. I am a former US Develop Team athlete who can recognize national and international level coaching talent. Master Jang is a rare talent at his sport and he is incredible at connecting with the students. Highly recommended.

My Daughter became Black Belt on 2018, I could not be more thankful to Master Jang for being an Example and Exellent teacher, I was able to see how my daughters mind got stronger towards finishing tasks and also physically! She got so strong It makes me laugh sometimes when I play with her of how easily she throws me around! I honestly believe JSK Tae Kwon Do is the best martial arts School in NJ!
