The Diamond Bar Mathnasium has been a wonderful experience for our family. Nick and his team have been kind, skillful and warm. They have with sensitivity and skill fostered their confidence and helped them grow in their understanding and execution of math. I highly recommend this facility both for the content and the personal. read more

Terry is the best math tutor/teach I have ever had! He doesn't just do everything he can to help you understand the material, he really makes an effort to show you that he cares. He even let me study at the tutoring center when I wasn't being tutored by him :D Terry is the best tutor you can find and Mathnasium of Diamond Bar really reflects it :) read more

This place is one of the best math tutoring places I've been to, and I have been to a lot. Terry, the director is honestly one of the nicest people I've ever met and he's a great teacher. He is kind, patient, friendly and very hard working (: I've seen him stay until midnight before helping people, that is what you call passion and dedication! The other tutors are great too! But I was only tutored in calculus AB with Terry and he makes it very easy and I never feel shy about asking Terry to repeat anything because I know he is more than willing and glad to help me understand. Everyone should come here I love it! read more

HANDS DOWN the best tutoring center in the universe. nuff said (': I have never enjoyed math so much as I did at Mathnasium. AND TERRY IS THE BEST TUTOR EVER ! read more

Look no further! My kids are in the 7th grade advanced math. This place is awesome!! We initially started at this location when they were struggling with math 4 years ago. We had switched out to another location closer to home, but have found our way back here. You can't beat the attentiveness and care that goes into this location. Nick and his staff are wonderful and appreciate the importance of ensuring the kids excel not only in their existing curriculum taught at school but also with any fundamental foundational math needed to get ahead. They truly care about each child's individual success. Hands down the best math facility in both the Walnut/Diamond Bar and surrounding areas. read more

Mathnasium is a great place to learn math for kids. I see my son's progress no long after he started to take lessons there. And most importantly, he likes to go! The instructors are nice, the director Kathy is vey responsible and always keeps me updated. Highly recommended! read more

I have been taking my daughter to this Mathnasium location for two years. Nick and his team did a fantastic job conquering her fear of Math and now she is the top of her class in this subject and ahead of her grade level. My daughter enjoys the environment and the teachers. The schedule is very flexible and the price is well worth the investment. I would recommend this location 100% to any parent who feels their child needs the extra help and even to those parents who want their kids to be ahead of their class. read more

It's hard to find a place with both good teachers and good people. It's usually one or the other. However, I confidently say with honesty that Mathnasium has both. I am currently Terry's student taking Calc AB. I cannot recommend a more rewarding place. He is professional at understanding the needs of different students, and being able to approach the student through different ways. The teachers have the patience, the eagerness to help, and the flexibility to accommodate the needs of different students. PS. Terry does not make mistakes. read more

So last week was my last week as an instructor at Mathnasium of Diamond Bar (so this review is the truth and I'm not doing it for a raise or anything ha ha) I worked for couple tutoring centers in the past, but what makes this one different is the crew. When Terry hires an instructor, he doesn't look only for the educational qualifications, but he looks also for how much the instructor cares about his/her students. It is safe to say that all current instructors truly care about their students and a lot of them actually stay over their time sometimes to make sure their students understand the materials. Instructors love what they are doing and Terry makes it even more fun with the weekly lunches to catch up on where we stand and talk about how we could improve even more. Terry always cares to make summaries of all the books' chapters, plenty of questions for any topic you can imagine, and review sheets. When a new student arrives at Mathnasium, he/she takes a pre-assessment that basically tell us what areas he/she needs to work on. Based on the results we customize a different plan for each student. Therefore, each student has his/her own unique binder. Usually, each student will be assigned to one instructor, but in case he/she goes with another instructor, the new instructor would know where the student is at from the communication sheet between instructors. At the end of the month, each student's parents get a progress report from the student's instructor showing what he/she has done so far, what he/she is working on, and the student's study habits. The review can really go on and on, but in summary: awesome crew, awesome management, and awesome quality delivered! If you want to improve your Math skills, I would highly recommend that you go to Mathnasium of Diamond Bar :). read more

It's the little things that sets apart this Mathnasium from other learning institutions. Terry truly cares about the students. On your child's birthday, Terry will always have a birthday cake ready when you arrive at the center. Terry takes his 5-6 teachers out to lunch once a week which allows Terry to catch up with all of the teachers, and the teachers to establish bonds with one another. This in turn translates to teachers who are happy with where they work and a more caring and professional attitude towards helping their students. Terry wants the parents to know exactly what their child is doing while he/she is at Mathnasium, and what the long term learning plans are for each child. Every student has a curriculum which is personalized to that child's strengths and weaknesses. Mathnasium is designed to help the student work on improving his/her weaknesses in each subject of math while reinforcing the student's strengths. The price is not cheap, but it is more than reasonable, and you would be hard pressed to find more value at any other institution. Other places want your money, Mathnasium wants your child to learn math, plain and simple. If you are considering having your child attend Mathnasium, I would recommend you go there to consult with Terry and you will quickly see why this place is one of the best in the area. read more

We joined Mat­hnasium's summer clas­ses to help my daughter bette­r prepare for middle ­school. Nick and his ­staff has helped her ­tremendously ever sin­ce, not only on her m­ath concepts but also­ her confidence level­ in math. Nick helped­ us to set up a learn­ing plan based on our­ needs and provided r­outine report updates ­about her progress. W­e noticed her calcula­tion is more accurate­, her knowledge for e­lementary math is muc­h more solid. Math ha­s become one of her f­avorite subjects at 6th­ grade! She's done we­ll in her math tests ­so far. We know she's­ in good hand with Ni­ck and his team. Our ­money well spent! read more

I interned here in the summer and you can tell that the owner of this place really cares for his students. He takes the time to get to know each and everyone of them, because that's the important thing in my opinion, if you can't have a personal relationship with the students they will not understand why they are there. The tutors are really patient with their students and take the time to explain why everything is, which is important for math, because now being in College it isn't all about knowing how to compute the equation but rather sometimes the theory behind the math problem. I would highly recommend this place to anyone that doesn't understand math and wants to get help or anyone that wants to get ahead. read more

I love this center. Both of my kids go there and instructors help them a lot , since the school's program going through the subjects so quick that the kids have no time to understand it to it's core. I have tried Kumon before and that was a waste of money. This center is different. They help my kids with subject they do not understand, homework and if everything is going well they would have their own mathnesium stuff they give my kids so they would understand the subject better or go ahead . Owner of the studio is very understanding and helpful. She always try to help you any way she can, either it is class reschedule, tutor for your subject or help with kids tests ( if they did not do it very well). I am very glad I have them. I am not expecting them to make my kids a genius, I just want my kids to understand the subject very well. read more

I've been taking my son there for 2 years and love the place. Terry, the owner, is excellent. He's caring and really cares for the kids. He instills confidence in the kids. read more

Terry is an awesome teacher & makes math fun and easier to understand for students like me who struggled with some of it. Beyond that, he is a person with inspiring words and the sweetest heart! read more

It's really an amazing, amazing tutoring service. My brother and I started going since this location first started up, and it's been incredible the whole way through. It sounds weird, but I was actually very okay with coming here. I honestly did enjoy being at Mathnasium, even though math is not my best subject and has always been a major source of grief for me. It doesn't feel like a chore to come here, essentially, because all of the tutors are so friendly, competent, knowledgeable, and accessible. Am I exaggerating? Not one bit. Terry really truly cares about students, and his passion for teaching math comes through in how he makes sure the other tutors reflect that same level of care. This isn't a punch clock job that people can just do for the sake of getting money; these tutors CARE, and it shows through in how they interact with their students. One of the things that Terry sets out to do is to make math less intimidating, less frustrating. I'm incredibly math averse, and would never say that math is my favorite subject, but Terry really did make it okay. I really enjoyed how everything just clicked when he took the time and extra creative effort to explain concepts that just flew straight over my head in class. I wholeheartedly recommend Mathnasium of Diamond Bar because they don't treat you as just another walking check. The tutors truly do care, and go out of the way to address your specific trouble areas. Parents, you'll never have to be afraid about not being able to get any information out of your child's progress out of them, because they make sure they know your child's strengths, weaknesses, struggles, and improvements. They want your child to do well, but more importantly they want your child to not have a crippling fear of math, to emerge from this experience not necessarily wanting to major in Applied Mathematics but at least with the feeling that it's not a complete, unconquerable enigma. read more

Nick van Vleit and Mathnasium of Diamond Bar deserve 6 stars. Incredibly knowledgeable staff and Nick is incredibly friendly. They will change your child's life! read more

I've been to a lot of tutoring centers in the past and I have to say that the Mathnasium of Diamond Bar is one of the best ones out there! There is an uplifting atmosphere that promotes positive learning. The instructors here are amazing and very helpful. They genuinely care and really do just want to help your child. Terry Liu (Owner) and Linh Phan (Center Director) are two amazing people that work their hardest to help both the parents and the students. They do their best to accomodate any scheduling issues or any other details that might need resolving. The Mathnasium of Diamond Bar is definitely the right place to enroll. This is the best choice you will make! read more

This is an awesome place to go for kids looking for math help. They are helpful for all levels of students. Ms Kathy is the best and you should go see the director. She will kindly help you with any of your questions and needs. I thought this place would be like Kumon but it is way better from my experience and my kids enjoy it a lot more. Highly recommended. read more

Our first official class was a success! Ms. Kathy and Nick were both there to greet me and answer all and any question I had. They are super kind and helpful. Ms. Lin was our teacher today and Mila was so happy when I picked her up. We have had such a great experience so far. This place really knows how to work, talk and motivate young kids. I'm so excited for your Mathnasium journey and most important my daughter is happy there! read more

My daughter initially was reluctant to come here and Nick and the team made her feel comfortable with Math. She has always received a C in Math. Barely making it and never feeling confident. I'm happy to say, she received her first A ever in Math. She is thrilled and so are we. Thanks Nick and team for helping my daughter feel confident in Math! read more

My two daughters have been attending Mathnasium For about 6 months. I decided to enroll them when my 5th grader was scoring below standards in math and my 8th grader was in danger of failing Algebra. By the end of the school year, my 5th grader was at grade level in math and my 8th grader went from an "F" to a high "B"!! The girls really enjoy the environment there: great and friendly tutors, motivating prizes, and a wonderful director who is very engaging with the students and their parents. I cannot express enough how much Mathnasium of DB has helped bring our family peace of mind knowing our children have the support they need to achieve their greatest potential in math. read more

BEST TUTORING CENTER EVER! The tutors actually care about the students and Terry, the owner, is just awesome! He has a passion for his job unlike other tutoring places who are just in it for the money read more

I've been going to Mathnasium for the past 4 years and this is as good of a tutoring place as tutoring places get. The instructors are extremely patient with their students and are always ready to teach whoever needs it. Before Mathnasium I was a student hating the simplest of math equations. However after Mathnasium, I have learned to love problem solving, and Mathnasium has helped me learn that with Math, the benefit of solving a problem outweighs the difficulty of that problem. Mathnasium has helped me learn to enjoy math, and I believe it can do the same for many others. read more

Nick and his team are amazing! Teachers are very nice and patient.My girl has improved a lot on her pre-algebra with their help.

I would not take my kids anywhere else. The director is professional and puts his best effort to each and every student as if he/she is his own child. His staff and teachers are highly trained and passed vigorous tests to work here. I love mathnasium of Diamond Bar and would recommend it to everyone. read more

Terry is one of the most selfless, dedicated, and kindest people I know. My best friend introduced me to him and he offered to help. He took time out of his busy schedule to help me every week. I've had many math tutors in the past but none like him. He is so patient and always happily went over material that I didn't understand (trust me, it was a lot). His passion and love for teaching is so admirable, he will go any length necessary to help students achieve their goal. Also, there are cool prizes you can win for getting good grades on tests :) read more

This is more than just a tutoring center. Terry really cares about all his students and takes teaching to the next level. This isn't just a business for him--teaching math is something that he LOVES and DEEPLY CARES about. Students jump right on with his enthusiasm for math because he makes learning, and shockingly enough, math, FUN! Terry and his entire staff is dedicated to making each student better, not just in the current class he/she is taking, but in the long math career that most students today have to endure. Trust me on this--there are no other tutoring centers around like this one. If you want your student to succeed, get them to Mathnasium of Diamond Bar! read more

We are very pleased with the performance of our boy in his algebra class since he started at Mathnasium. His comprehension of his homework and his performance on quizzes and tests is greatly improved. He has gone from an F to a C in three weeks and is now headed to a B in the class. We previously tried a private tutor and did not get these results. Thank you Mathnasium. read more

Hi! I think Mathnasium is the best place to get tutor if you need help in math (: I went there for Calculus AB help and Terry, the tutor, helped me understand the concepts and even went into deeper explanation about how things work. Because of him, I got a 5!!!!! on the AP test. For that, I'm truly thankful to him :) Terry is not in it for the money, but rather because he loves loves LOVES math! You don't find a lot of people like that nowadays. So if you need help, go to Mathnasium! You won't regret it! read more
