Customer Testimonials
Dravin looks forward to his session with Ms. Joann every week.
My soon to be 8th grade daughter has used Mathnasium in Denville in a variety of ways over the past few years. This summer she completed the Algebra Boot Camp. She found this camp incredibly helpful and feels well prepared for her upcoming Honors Algebra course. She has already stated that she will be enrolling in the Geometry Boot Camp next summer. The Denville staff is awesome and Debbie, the owner, is fantastic. My family highly recommends Denville’s Mathnasium programs for those who need extra help or those who are looking to get/stay ahead!
My son was really struggling with math and has made such a great improvement since starting up with Mathnasium Denville. He never complains about about going to tutoring and is interested in math now. His grades have improved tremendously and he enjoys learning with the tutors there. Thank you!
My son improved tremendously tutoring with you. The reward system is a big encouragement for him. He love math now and want to be a professor of mathematics when he grows up and teach mathematics in Mathnasium when he turns sixteen.
Denville Mathnasium makes math easier and fun! The instructors are great. There is feedback of what your child learned at every session. There are monthly assessments and annual reviews.

We are happy to see our daughter enjoying Maths
Very much stress free environment, which helps kids to focus & have fun in learning.
We continue to be so pleased with our Mathnasium experience. Debbie and her team provide a fun and supportive environment that motivates our daughter to do her best. We often have to wait 10-15 minutes after her session for her to finish a game!
Great program and love the flexibility with the app!
The kids learn a lot
I am so pleased with how much my son is learning at Mathnasium. The tailored curriculum is super important. The kids really enjoy coming. When I raised an area that my son needed help in, Debbie the owner ensured that he was provided extra help in learning to slow down and read the word problems very carefully. Debbie truly cares about all of her students and parents.
Absolutely love the program and especially Debbie. My kids have excelled!
Very flexible with scheduling.
I love the confidence that Mathnasium goes to my daughter.
Staff is welcoming and helpful. My son has learned a great deal.
Very personalized learning experience. My daughter enjoys her lessons.
Excellent all around!!! Debbie, the owner, is top notch in all regards. I can’t believe my 6 yo daughter enjoys going to math classes!
We see notable differences in the way our son approaches his math problems. Love the program!
My son has had a wonderful experience with the tutors. He will definitely be returning.
We are so pleased with our child’s experience at Mathnasium-Denville since starting 3 months ago. We signed up hoping the program would increase our child’s confidence and reduce some of the anxiety they were feeling about math at school. We had heard good things from other parents and liked that the system was not just rote memorization and endless drilling. In our opinion it really has been an unmitigated success, grades are excellent and now our child finds math fun! I would recommend Debbie Lum and her team without hesitation.
Teaching is personalized.
My high school junior was struggling with precalculus so we signed him up with mathnasium. He is getting the skills he will need to be successful, not only in precalculus but also on the SATs or ACTs. It is also a big help when he has homework because it is immediately explained for him and he doesn't have to wait until his next precalculus class with 20 other kids and their questions. He may not love the extra hours of math, but he will admit that it is definitely helping him!
Is very important for my daughter
Debbie has been great to work with and very accommodating. All the instructors are very knowledgeable and helpful at explaining the problems that they do at the center. The curriculum is individualized and based on areas that the student can use improvement, so it doesn’t perfectly line up with what they’re working on in school. But it definitely translates to improved understanding of what is being taught.
I home school my 7th grader and I bring him to Mathnasium five times a week. He loves coming and they always tell me how hard he works there. I appreciate all the help they give me.
We love Debbie and Mathnasium! We looked at other places and nothing compares. It’s expensive, but worth it on so many levels! Couldn’t be happier!
We would like the center send us some documents(questions, subjects) done at Mathnasium. Everything stays inside the folder and parents can’t see anything. Also less play time would be better. Other things are great.

My granddaughter absolutely loves going to Mathnasium. She says they make math fun snd easy to understand. We highly recommend Denville Mathnasium to anyone struggling with math as well as those who want to sharpen their math skills.
