Debbie and her staff are just phenomenal. My kids always get an A after each tutoring session. Debbie is so accommodating, knowledgeable and very professional.
Mathnasium in Denville is a wonderful place that has helped my kids accelerate in Math. Ms. Debbie Lum and her team are very knowledgeable about the curriculum in the schools and are very flexible with how the sessions are run. We use Mathnasium as a supplemental tool to keep their math skills above average. Although we find Mathnasium's curriculum to be excellent, on occasion, we have asked the teacher to assist with homework or review for a test, which has been very helpful. I HIGHLY recommend for all ages and for all levels of math!!! - H Last name removed

My son really enjoyed the workshop he took over the summer for Algebra…
My child loves attending ,
My son had a tough time with virtual learning. Mathnasium was filled with kids his own age who had similar difficulties with remote learning. Mathnasium helped him fill those gaps and gave him confidence. I would recommend it without reservation!
My son really enjoys learning Math with Mathnasium. I love that he can catch up on all that he has forgotten to prepare for the school year ahead.
Mathnasium has been great in helping my child fill in gaps in their mathematical knowledge. Thank you!
This is my second child using this program - and it is truly wonderful. Debbie, the owner, is a gifted teacher and her staff is very nice and clearly well trained. Not only do the kids learn but the Denville Mathnasium team makes it fun!! Best tutoring math program that money can buy - I can’t recommend it enough!

Mathnasium of Denville us filled with great instructors who care about the kids. The management team is fantastic and go above and beyond for individual support and attention to both the students and parents. I am honored to give them my highest recommendation!
It is an excellent program with wonderful instructors.
Excellent
Mathnasium has been a blessing to assist my boys with Math Tudor help. They have been in the Denville Mathnasium program for three years now. They previously went to a one on one Math Tudor. While this was helpful it did not accomplish what Mathnasium has mastered in creating an individual assessment and learning program to focus on their needs. I highly recommend this program as it has changed my boys attitude and ability to take initiative on their own to complete homework and increased confidence in test taking!
Incredible staff and learning experience!

Our three sons are always excited when they attend mathasium. The director Debbie and staff have a nice rapport with our boys. We can see their confidence in math improve.
