One Best Martial Arts Programs in the country. Great Instructors, discipline with the students in a positive way, and great instruction. Very highly recommended.

Mr.B and instructors at the school were friendly and accommodative when we had joined. Things were different once we had to leave the school as we had to move out of state. Have been waiting for the refund for more than a year now and there is no response to calls or mails from Mr.B. Had trusted him to refund when we had left as he mentioned it would all be done quickly. Suggest to be cautious on the money front and have everything in writing.

Exceptional school with incredible instructors. Mr. B and Mr. Jake are the best!

I have been training at D4 for 8 years of my life and can I say I learned so many things here. From self respect to, how to protect myself in a bad situation. D4 is like my second home. I love all the instructors who got me to where I am now, and all the friends I made throughout the years. If I didnt start karate here I dont know what id be doing now. Thank you to everyone at D4 for being patient when I was young and learning, and for being stern and supportive when I grew older. D4 is such a fun place to be and I always looked forward to going to class to train. Overall im so glad I stuck with it and kept going. for anyone of any age who wants to learn respect, discipline and real martial arts you defiantly need to join n D4 it will do you good.

The staff is terrific especially Mr. B the owner who is very down to earth and is very helpful in giving suggestions. My daughter has been going to the after-school program for a year and loves going. She gets excellent help with homework. Theyre always doing creative and challenging fun activities. Every time I pick her up shes never bored. She has requested I pick her late because she loves it there! We plan on enrolling my other two kids to D4K. Thank you very much!

Our son attends classes at D4 and we have been impressed. The instructors are able to have fun with the kids while still pushing them. The classes have a great mix of skill building, fitness and fun. Plus, our son has improved self-control and is learning an even greater sense of respect for adults and peers.And the parents nights out and day camps they do are awesome. The kids get karate classes, play time and the ability to meet new friends.

Excellent place, Coach Danny is awesome. Our son”s performance at school has improved significantly after training here. Have been going there for the past 2 years. Highly recommended.

I started taking my daughter to D4 Karate about a year ago, and through this class I have seen my daughter grow faster than I could ever have expected. In addition to her acceleration in karate I have seen great improvements in her cognitive ability and fine motor skills. I would recommend this school to anyone, they do an amazing professional job. I can really tell that they care about what they do and the children they work with.-Marshall

This school is one of the best karate schools that I have ever been to. The instructors are fantastic and the students are great. The overall environment is amazing. If you want you or your child to develop worthwhile skills then this is the place for you or your child.

Ive never been an actual student here, but, Ive just did a trial to see If I want to do it. I liked it but my dad forgot to enroll me. So Im planning to actually join D4. I did the trial about 1 1/2 years ago. It looks fun and interesting. I hope I be a student in a few months!

D4 Karate is the best Martal Arts School in the area.Mr. B and his instructors keep students focused on learning, working hard, being competitive, and respectful. This is something that will help students not just in the Martial Arts arena. There is also a friendly community environment in the school.I highly recommend D4 Karate.

My kids love going to D4 Karate! The instructors are top notch. They have fun while learning self-discipline and respect. I highly recommend this karate dojo.

This is a great program and the owner and trainers are friendly and very accommodating. My son has been attending for the past 7 months and his mobility and focus improved quiet a bit. We highly recommend this place and kudos to the owner and the team.

Ive seen D4 karate students of all ages at many tournaments and they always seem to stand out from the rest. Their attitudes and performances speaks volumes about their martial arts upbringing. My niece also trained here and I saw a vast improvement in her self-confidence and social relationships with friends. The location is convenient, the people who train there are uplifting, and the staff are incredibly experienced. A+

D4 Karate is a great community learning center that teaches through play. My kid used to be shy now she is gradually learning to be confident and focused.The instructors are all skilled and give their best. I would definitely recommend it to all interested parents/students.

From what I have learnt from parents of kids going to other such schools, D4 is the best. I like the way the instructors and black belt students take their time and help student master every skill required. The dedication in getting every student to succeed is top notch at D4. I would recommend them anytime.

Best karate school in the area! Great instruction. You can tell by the quality of the students. I would highly recommend trying a trial class!

Ive been training at D4 karate for the past 8 years, and I highly recommend enrolling here if you want to learn real martial arts in a positive, competitive, and supportive environment. Students will grow both physically and mentally thanks to the leadership of the highly trained and devoted instructors.

Editing below posted review as I got refund after Mr B read the review.Earlier I had given 1 star but now updating to 3 star.Issue: Mr B told he would refund us around 100$ since we have to move to CA. But reaching CA and trying to reach him 30-40 times, leaving voicemail there is no response.If anyone planning to join I would suggest to be cautious of his words. Have everything in writing and keep a copy of same with you for record. My mistake was he told he will refund and he noted down in his file too. I trusted him that for 100$ he won’t do kind of thing.

The place is extremely tiny and it’s always over crowded with plenty of kids. I wish they could conduct smaller groups in a much better and bigger place. Otherwise everything else in terms of the program is designed very well.

All good instructors are gone. One old guy teaching with no energy and passion. overcrowded and chaotic.!!!!

My son has learned that to accomplish something worthwhile he needs to work really hard and stay focused. He has learned the value of hard work and confidence and that he can accomplish something if he tries really hard. I see him smiling big after Karate Training. D4Karate is a great way to help with self-discipline, emotional and mental development.

What a school. Its amazing this school teaches you how to be successful in life and teaches you a lot more.I recommend for you to go to D4 karate and Ive been here for at least 5 years and Ive enjoyed and you would to.Go to D4 karate now !!!!!!

Master Boccagno and his instructors at D4 teach real martial arts as well as lessons that go beyond the training floor.

Self Discipline and practical self-defense a most go to for top martial art athletes

Best school in the area. You can really tell by the quality of the kids!

My son liked a lot, this is good place to learn karate.

D4 karate is in a class all of its own. Theres no other Karate school out there like D4!

Very poor.. he has so many ways to get money from your pocket. practice area is very unhygienic. Toilet is always dirty. He sometime says to kids to go to near by chuck e cheese for toilets.

Very friendly and professional from kid to youth, adult rate 6 stars if there have 6 stars

Very disappointing..
