At Mathnasium, we help kids understand math by teaching the way that makes sense to them. Children who consistently attend sessions at our learning centers enjoy a transformative learning experience and make huge strides in the classroom.

Attitude: When math makes sense, kids develop a more positive attitude toward math.

Understanding: Mathnasium teaches for understanding, giving students the ability to succeed in any math environment. As Larry Martinek, Mathnasium’s Chief Instructional Officer notes, “It's pretty easy to forget things you memorize and near impossible to forget things you understand."

My son is coming home from school and saying that he is ahead of all his class. He said it’s all because of mathnasium. Rich is amazing. He cares so much about how the children are doing. Makes sure my son gets out safe and that he is a good match with All the teachers. He gives the children different ways of solving math problems.

Rich and staff are the best, knowledgeable, professional, my son was failing math miserably and through the tutors at Mathnasium, he finished geometry with a final grade of 100%. 😀😀

Mathnasium was a total game changer for our son who was struggling in math. He has improved immensely with the help of Mathnasium’s amazing team, and his confidence level is so far beyond what it was when he first started. We are so grateful to Rich & the team at Sayville Mathnasium!

Rich and the staff have provide not only great professional math tutoring. They have provided something that has been invaluable, social interaction. As the Connetquot Schools and the Teachers Union refuse to provide these video interactions for our children. Rich and his staff have put children first. I can't praise his handling of this situation enough. He truly cares about kids and all aspects of their learning! If your child needs help in math. Reach out to Rich!! They are incredible! I would pay double for this type of caring and service!!

May 15, 2020
Such a positive friendly learning environment that my daughter has benefited from with grade improvement in a short period of time. We love our mathnasium team!

The tutors are great and always engaging with the kids. The distance tutoring has been great for them as well since they can still get their math tutoring and help with schoolwork especially since they don’t have their teachers in front of them due to distance learning.
April 14, 2020

Mathnasium works on every level-it allows the student to learn at their own pace, to work independently but with supervision and guidance when needed, and to experience the fun side of learning math. I applaud everyone at Mathnasium, from Rich to every instructor, for their dedication to insuring each student gets the necessary tools he or she needs to succeed at math.

Online sessions have been going great!! Gives my kids access to a live tutor to work with. This is far superior to any of the instruction provide by the schools.

Our daughter likes math thanks to Mathnasium! I did not think she would ever like math but the team at Mathnasium did it. Math is not the struggle it once was. Thank you!

Susan Insinga
Our son has been going to Mathnasium for about four months now, and the change in him since he started is truly amazing. We are beyond grateful for Rich and all of his staff at Sayville Mathnasium. One of the biggest changes we notice is how John feels about math compared to how he felt before. There are no more tears during homework, no more frustration trying to figure things out. They have given him the tools to work through problems and he has gained so much more confidence in himself since going to Mathnasium. He goes three times a week and it's something he actually looks forward to doing, which I think speaks volumes. His math average has gone from a 52 to an 88 and just keeps getting better and better. We are beyond proud of his accomplishments and it's all because of the hard work he puts in with the Sayville Mathnasium team and the approach they use to work with these kids. One of the best decisions we've made and we are so happy we did!

February 11, 2020
Carmen Alicea
The best decision I have made as a mother was to register my daughter at mathansium she has advanced so much on school it has being like a 360 her grade has gone up I have to said Richy and his amazing team has being so patience and helpful with my daughter on all her progress I have no words to said how grateful I am

Great Instructors and super caring and accommodating staff. Very happy with our experience.

January 7, 2020
My granddaughter went from a struggling, barely-passing student in math to one who just got an "A" on her report card! Mathnasium has given her confidence to tackle math problems without the fear and confusion she previously experienced. The instructors at Mathnasium are very patient and have a true desire to teach the student how to successfully execute the math they are working on at the time. Rich understands what is needed to get a student to perform at or above the level they are currently working on, and he ensures that everything is done consistently to achieve that goal.

January 2, 2020
Mathnasium is a great place for students to build confidence or fill in learning gaps. Rich listens and will help design the best program for your child. His instructors are knowledgeable, approachable and patient.

Our daughter started MATHNASIUM I’ve this past summer, after a tortuous year of math, where she struggled, lost all confidence, and barely passed. This year, after her experience at MATHNASIUM, there’s been a complete, total turn around. She’s flying through her math skills, and has been maintaining a mid-90’s average and is actually ENJOYING her math class and learning!!! We can’t believe her progress. It’s really unbelievable. So grateful to have found MATHNASIUM... just can’t recommend it enough!!!

Since my son has started going to Mathnasium, he has definitely been more active in school and more motivated to succeed in his classes, not just math. Although it has only been a little over 30 days, I notice the difference in how he approaches homework and studies for tests & quizzes.

November 29, 2019
We would like to thank the management and staff of Mathnasium for accommodating our Son's study needs by developing a College level Calculus II study plan for him. We were referred to Mathnasium by some parents of High School students who had success with the service provided. When we initially met with the Rich, he advised us that they were primarily geared towards working middle and high school students, but not College students. Without hesitation he offered to develop a personalized study plan for him, which has made a tremendous improvement in his level of understanding and confidence with his school work. Many thanks to Rich and Shannon of Mathnasium! [FIRST NAME REMOVED] and Jeanne [LAST NAME REMOVED]

Charlie Groh
My daughter attended Mathnasium for 6 months and there has been such a transformation. She started out very behind in math with failing grades, no confidence and didn't understand basic concepts. All I can say is now in middle school her math teacher recently said to her " I thought your mom said you struggled in math." Her confidence has improved so much! She's no longer nervous or demanding I sit and do her math with her. Mathnasium is a wonderful organization and helped us so much! We are forever grateful! The staff was amazing, welcoming and really made math fun to where my daughter would ask to go!

November 7, 2019
Geraldine Valentin
My girls are more confident in the classroom and their grades have improved tremendously since we started using Mathnasium.

My daughter has been struggling in math for years. I signed her up for Mathnasium and She has gone from fIling grades to getting 80’s and 90’s on tests and quizzes! I wish I had signed her up sooner!

October 25, 2019
Phyllis Barone
My granddaughter has been going several times a week for about 4 months and I definitely see an improvement in learning how to understand and solve a problem. She enjoys going and it's nice to know having math homework is no longer an issue because they work with her to understand and do it correctly which has built her confidence. All the staff and Rich are all great!

October 7, 2019
Every student, no matter what their skill/grade level, will benefit from regular attendance at Mathnasium. Rich has assembled a group of very bright, caring and patient instructors who help students master all math concepts, whether simple or complex.

October 6, 2019
If your child is struggling with math or just wants to improve their grade; Mathnasium offers a pleasing, supportive environment. Rich is super to work with and listens to your concerns. The staff is encouraging and provides great feedback. My son significantly improved his Math SAT score and my daughter has consistently raised her grade in math each quarter.

Cathy Murphy
This summer my son JJ attended 10 math sessions at Mathnasium of Sayville. When JJ began his sessions he had a very negative attitude towards his ability to learn math. During the 10 sessions at Mathnasium I started to see this attitude change for the positive. On JJ’s first day of seventh grade as he came home from school his first response to me was that he thought this year he would do better in math because he already knew about the first topic on integers from Mathnasium. Now JJ has the confidence to do what he needs to do. His first test grades were 82 and 85 thanks to Mathnasium!

Staff is amazing!! My daughter started at MATHNASIUM with a fear of math and absolutely zero confidence. After only a few sessions, she is LOVING MATH and her confidence is back!! She couldn’t wait to start school and get to her math class!! Something she dreaded, is now her favorite subject!! I can’t believe it!! Worth every single penny and then some!!!

We came in on the "fly" did not have much time for my son to get up to speed for a College placement test, but the staff was great. Super accommodating and helpful, it was exactly what my son needed. Aced the placement test and got into the program of choice for his upcoming Freshman year. Tutors were super helpful and very responsive to his needs. Totally awesome team at this location.

July 9, 2019
I would highly recommend Mathnasium! Friendly and knowledgeable staff. Rich always takes the time to listen and build the program that will best help your child succeed. You will continue to receive feedback on your child’s performance and progress.

Jeanne Collins

My daughter is enjoying her time spent at Mathnasium, and it is often that two hours go by and she still wants to stay a little longer. She enjoys the format of the binder and the mastery checks, along with the ability to work on her homework if necessary. She is more likely not to make a silly error as she aspires to get a perfect score on her mastery checks. She was comfortable with math when entering Mathnasiun, but is now acquiring a self-confidence beyond what she previously possessed. The tutors are always available for assistance, and they are also very kind and patient. She actually has fun while there and looks forward to going often. The owners are kind and professional, and it is apparent that they really care about my child’s progress. This is my daughter’s first year there, and she plans to continue.

January 6, 2019


My daughter has been attending Mathnasium for over a year. Her confidence has grown and she has become a 90+ math student. When she began, she hated math and thought she would never do well. Rich creates a great atmosphere for learning and the instructors are motivating.

January 5, 2019


A very positive learning experience. My granddaughter struggles in math but looks forward to going to Mathnasium to get the help she needs. Every person there, from Rich to all the great instructors, are super friendly, extremely professional and know how to relate to young children and how to help them understand math. They are very patient, going over and over problems until they are understood. They are not just there to do a job, they all seem to have a geniune desire to make sure their student for that day comes away understanding the concept because they want them to succeed at math. I would recommend Mathnasium to anyone needing help in math.

The owner Rich was extremely helpful and took a great deal of time answering all of my questions during my initial visit. I was impressed by the setting of the center (a little more laid back than a classroom) and felt confident that my daughter would enjoy going... so far, so good and she is already understanding slope of linear equations better!!!!

December 7, 2018


Mathnasium offers excellent math tutoring and support. Rich and his team are very caring and dedicated to each students success. They take the time to learn each students strengths and weaknesses and create an individualized study plan. I have seen great improvement in my daughter’s confidence and grades in both algebra and geometry. She is no longer frustrated or discouraged - many thanks to Rich and his staff. We are truly grateful for your support.

November 25, 2018


I am very grateful to all the tutors at Mathnasium for helping my son better understand math. This is the second time I signed him up, once in elementary and now in middle school. He was struggling to keep a C average and once in mathnasium he was able to bring his grade up to an A both times.

Since starting Mathnasium this summer, her confidence and math skills improved SIGNIFICANTLY! She went from getting 50's and 60's to 90's and 100's! My family is so grateful!! I can't thank them enough and my daughter absolutely LOVES going.

October 4, 2018

It was been a wonderful experience and has been helping my child!

March 7, 2018


My daughter has been struggling in math for quite some time now. I had gotten a tutor for her, but the once a week just was not making an impact. She has been attending Mathnasium for a month now. She is getting a foundation for math skills which she was lacking. My daughter is extremely shy and I just wasn't sure how she would do but she loves it. She enjoys going and her teacher has seen confidence in her approach to math. The staff is wonderful and they know my daughter. She works there and shows great concentration. It is a relief for us to see her make steady gains and begin to close the gap.

February 14, 2018


My husband and I are thrilled with Mathnasium and how Marisa is progressing in her math studies. Rich is wonderful and so accommodating to Marisas needs. Marisa is eager to practice math now and really enjoys it! Thank you to the entire staff at Mathnasium!!

Rich and his team especially Shannon have made such a difference in my daughter’s life. They have helped to improve her math grades as well as help her self confidence.

We appreciate all their support and efforts.

My son went from a C math student last year to an A student this year! I'm very proud of his improvement and grateful for the help the tutors at mathnasium have given my son.

It's great place to improve math skills. Teachers are really good. They teach the math in a way that make sense to kids.
