CenterDirectorLarry Martinek, Creator of the Mathnasium Method 

Larry Martinek, Chief Instructional Officer, Developer of Mathnasium Program. 

Larry has spent his entire career finding a better way to teach math. From inner city public schools to acclaimed magnet schools, to leading private and parochial schools, Larry has served as both a classroom teacher and as an educational consultant. He has designed the curriculum, teaching strategies, and teaching materials to help students and teachers learn math more effectively. He has trained teachers in the art and science of boosting students' ability to “do” math, thereby increasing students' math scores and feeling of self-worth. Larry is the developer of Mathnasium’s educational program – one of the most comprehensive and innovative curriculum ever produced for teaching math.

While Larry is not an Instructor at our Center, he is a valuable asset we can call on to ask about specific students' scenarios for guidance and advice.



Surani Peiris, Center Director 



Surani comes from a strong background in Finance. Prior to opening her Mathnasium center, Surani worked as an Investigation officer in HSBC and Senior Banker in Bank of America. She left her Banking career when her daughter started school and started an adventure in the Education world. She has experience in Early Childhood Education and Elementary Education. While working in the Public Schools as a substitute, Surani experienced that most of the students do not like math and think math is a hard subject. Then she figured the reason is the missing pieces in the students' Math foundation drive them to the frustration. When Surani introduced to Mathnasium method, she was delighted as this method makes math make sense to students. With Mathnasium's teaching methodology, Surani is very confident that children from any background or level can overcome obstacles to achieve greater success in school and in life. We are proud to bring the Mathnasium Method to your children and are happy to be your neighborhood Math learning center.
