National Taekwondo Center

Are you looking for a great Tae Kwon Do school? The school is National Tae Kwon Do Center at Diamond Bar. Six months ago, my son started Tae Kwon Do here. I like here beacause this place is huger and teachers are kinder than ather schools. They not only teach well, and help student keep good habits. My son is becoming stronger, more polite and more confident than before. These are very important for his growth. So, I think my choice is right.

NTC is simply the best studio in Diamond Bar and surrounding area. My daughter started with NTC when she was 5 years old, right before kindergarten. Learning TKD has develop her emotionally, physically and spiritually into the young lady she is now. Grand Master Sean and the 3 masters are excellent teachers and I trust them with my little precious. Beside the students, there are the parents. What can I said, we have to be happy too. It is a blast being there. The kids and the other parents are fun to be with. The studio holds events that are fun to attend. There are the tournaments that my daughter competes in. NTC has improve my family quality of life in many ways. Go «Team Titans»

My 2 younger kids have been coming here for a few mths now. This is the BEST thing I have enrolled my kids in, especially for my 8 year old son. His attidude and sense of responsibilities have greatly improved since starting here. The instructors instill respect, honor, and obedience in all their students. As a single mom with 3 kids, I was concerned about making a monthly commitment to keep my kids enrolled in classes, but trust me when I say is worth every penny I’m investing! They are very flexible with class times, offering classes everyday. My youngest daughter who is 6 years old loves coming to these classes with her brother. Go in for a free 1 time trial!!!

Very good taekwondo center! My son has very good experiences there. We usually went to there fourth a week. Now He’s really like learning taekwondo now.

The staffs are really nice there! They not only instruct students well, but they also take care of the students.
If you are looking for a Tae Kwon Do center, NTC is a definitely a GREAT place to go! :D
I really loved my experience there

My son started at this location before it became NTC (it’s been about 4 years now, possibly more that he has been attending)… We really liked the previous school and were nervous about continuing, but NTC has proven to be well worth the transition… We have had a very good experience here and our son enjoys being a part of this school… The masters and instructors that he has worked with are all very skilled and knowledgable, energetic, and firm but caring. He learned a lot about respect, responsibility, and having control through taekwondo… The masters really encourage having good habits in school and at home, showing love and respect to family members and friends, and never giving up…
We usually come for the 6:45 class and though it can get crowded, the masters/​instructors are very organized and are able to work with each group as they rotate throughout the class… The students learn how to work together and teach and learn from each other… I am amazed that these kids can use a bow staff or nunchucks and break boards or bricks!
They also host several get togethers throughout the year to build a «family» environment… Some of the get togethers involve all the schools so we get to meet with other students and families… I like that we have met many new people and have made new friends through NTC too…

Agree with reviewer LA G.‘s earlier review posted on 10/​14/​2013. It used to be a good place for kids, but not any more.
We were there for more then three years. Recently, I felt my son’s uniform is too small. So I asked school to buy a new one. The instructor told me a black or blue uniform for a 8yrs boy will cost $ 100. It is really expensive. Then I bought a new form online, cost me $ 30. On the uniform I bought has no any logo. I sewed NTC’s logo patch on new uniform. (The old uniform is from previous owner, since NTC took over the place gave us a patch with NTC logo)
Then the instructor told my son, he can’t wear the uniform that not purchased from them. I am just wondering here is a place to train kid Taekwondo or a place to sell uniform? If the price is reasonable, I am willing to buy from school. However, $ 100 for a uniform, I can’t say it is a fair price to a parent who spent more than $ 4000 to your school. (Sign up black belt package for $ 3500, each time belt test will cost $ 50 – 100, sparing equipment will cost $ 150, extra helmet cost $ 50)
When my son sign up, I paid for black-​blet club to previous owner. Black-​blet club means you can join any class with unlimited practice. But long time ago, my son has been told that he can only join the class for his level, so the time is really limited.
Also, as other parents mentioned, their student/​instructor ratio is really bad.
Now, my son is senior red, three more levels to black. But, unfortunately, looks like we have to give up.

I love NTC. I have been here since I was 9 and now I am 22 yrs old. Master Sean saw potential in me at an early age and gave me a chance to compete and also become an instructor. I know for fact that this school is not all about money. Masters here worked with me and my parents to support me become who I am today. I am currently going to college and assisting Masters here as an instructor. I can say confidently that masters at NTC are true masters where they really care about their students and bring out their true potential. I’ve seen how the masters work with the students personally for 12 years. They are the best at what they do. I have also trained with other masters from other taekwondo centers, but what made me come back to NTC is the true training and care the NTC masters put in to their students. If you want training, and discipline that will last a lifetime for your kids, this is the right place.

tl;dr: If you’re looking for a great tae kwon do school with an excellent community and a great workout space, this is it.
NTC Diamond Bar has a somewhat unassuming front – like many other tae kwon do schools, it’s located in an unassuming strip mall between a salon and a bank. When you walk in the door, though, you’ll notice the difference right away: This space is huge! Many tae kwon do schools are crammed into a space more fitting for, well, a salon or a bank, NTC Diamond Bar has somehow managed to find about twice the space. It has also managed to fill it with great equipment and enough seating that you can easily watch your kids practice.
Any martial artist can tell you that it’s not about the space, though: It’s about the people in it. This is where NTC shines. The masters and instructors, many of the latter taken from the student body itself, are skilled, patient, and extremely helpful. They’ll take you through forms, sparring, nunchaku, and – at black belt level – bo staff and swords. The student community is active and helpful as well; it’s easy to arrange carpools, and there are frequent school parties as well as an annual beach outing.
NTC has three other locations scattered around the greater Los Angeles area, and one of the best perks is being welcome at any of them. The price can’t be beat, either: NTC has a «three year» contract, but it’s actually for as long as it takes to get a black belt. (I have no idea what Sue P. is talking about; I was welcomed back after three years of training and a year off.)
I have fond memories of taking my black belt test at this studio, and give it my highest recommendation for someone who’s looking to build some memories of their own.

Please do not bring your kids here. It used to be a good place for kids a few years ago. We had a contract for 3 years and were told we would guarantee to receive a black belt before contract ended. My son was supposed to take a black belt test in December and we thought we only had to pay the belt test of $ 500. The master all of sudden told us that we have to pay the next couple months because contract was up. We told the master that the previous owner guaranteed that we our contract won’t end till my son gets his black belt. She said she did not see this in the contract and told us that we should sign another contract with her because their contract would guarantee to receive a 2^nd degree black belt. Well, this tells me all other TKD Center should all have the same terms in their contract. I also verified with another parent and she confirmed the previous owner said the same to her. It’s not about paying the additional 2~3 month programs. It’s about how they should stand behind their services. They purchased this business from previous owner and should honor the words the previous owner said. It was hard to tell our son to quit in the middle of preparing for a black belt test. Please do your research before you join any TKD center, read their contracts well and tell them to put down the important terms in the contract. Last, please sit down in a class and see if you could see any kids smile or enjoy being taught. Our lesson has learned and I hope the owner sees this review.

I love NTC. As a tkd parent/​fan of 15+ years I can attest to the fact that not all studios are the same. This studio has a MASTER teaching every class. Not an instructor– a Master. We’ve been here for over a year and there has NEVER been a day (4 days a week my daughter attends) in which either Master Soo, Master Young Sil, Master Sean or Master George have not been there. They are supportive to every student from young beginners, casual student and Team Titan members. Sounds like previous parent review has more of an issue with location and area. News flash– if you dont want to be surrounded by 99% asian people, maybe a taekwondo studio in Diamond Bar is not the place you should be.

It used to be a GOOD place for kids, it was when Master Sean was there often, and on top of everything (hence the 1 star).
Here is a list of problems:
1. The true masters is rarely seen at all (I say it because I come here 3 times a week, every week!). He has too many locations to run, so they have different substitute instructors all time, their English is hard to understand, and not kids friendly.
2. Student/​instructor ratio. As I am sitting here typing this review in the class, there are 12 students, 4 different belt levels, but only 1 instructor. It is a MESS!
3. Other annoying thing is: they are way too «money». They always on the mission to «sell, sell, sell, and up sell»: equipment, uniform, membership, etc.
4. 99% students are Chinese/​Korean, their parents are just plain rude and classless. They talk (or should I say «yell») loud during class, park their cards in handicap zone, pick up/​drop off their kids blocking the traffic.
We have been bring our kid here for over a year now. It was good back then, and we referred a few friends. But now it is a mad house.
