Bob D'Orazio

Owner / Director of Operations
BOB runs the business side of Mathnasium of Washington Township. He manages the Center on a day-to-day basis and is usually the first person every parent and student sees or speaks with. The opportunity to blend his business background with Kathie's education background seemed like a perfect fit with Mathnasium. Bob feels that Mathnasium is a great vehicle to build confidence in kids. "The Mathnasium Method develops 'number sense' that helps them succeed in math, and a whole new world opens up to them. That, in turn, builds confidence that is born of real accomplishment, confidence that spills over into all aspects of their lives. We have seen students improve grades in other classes because they no longer worry about Math." Bob earned a B.A. in Communications/Public Relations from Glassboro State College and has also taken additional courses in Business Management/Human Resources. Bob worked in Retail Management for many years. He served as a Commissioner for the Housing Authority of the City of Vineland for 22 years, the last twelve as Chairman. He served on the School Improvement Team while his children were in grammar school, and has coached both in-line and ice hockey while his son was a player. Bob served on the Mathnasium Franchisee Advisory Committee for the first two years of the Committee's existence. Elected to serve as a member of a committee of eight franchise owners, serving as an additional channel of communication for constructive, open, and two-way communication between the franchisees and the management of Mathnasium. He represented Centers in the Northeast Quadrant of the US and Canada. Lifelong South Jersey residents, Bob and Kathie have two grown children, a granddaughter (who attends Mathnasium), and a grandson.

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 to 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 curriculum, teaching strategies, and teaching materials designed 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 feelings of self-worth. Larry is the developer of Mathnasium’s educational program – one of the most comprehensive and innovative curriculums 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. This has helped to make visits more productive and enjoyable for many of our students.


Instructor since 2016. NJ Certified Teacher of Mathematics
ALLISON attended Rowan University, earning a degree in Mathematics Subject-Matter Education. She graduated in the top 5 of her class from Glassboro High School in 2015. She started taking math classes at Rowan University her junior year in high school. She has taken Calculus II, and III, Ordinary Differential Equations, Linear Algebra, Discrete Math and Intro to Real Analysis at Rowan, along with all honors and AP math courses in High School like Algebra 1 and 2, Geometry, Pre-Calculus, Calculus AB and BC, and Statistics. Allison is a Math Teacher at Winslow Middle School. Allison loves math and helping others learn to love it, too. She believes that most people do not like math because they never understood the key concepts early on, which makes everything else difficult. If students were taught in a fun, engaging way- like the Mathnasium way- she believes everyone would love math. Allison believes that everyone learns differently, so the customized learning plan and one-on-one instruction at Mathnasium is very beneficial and lets the student have personalized instruction. This helps build student’s confidence, along with the balance between independent and one-on-one work. Once a student’s confidence is built, they will believe in themselves and their ability to learn and do well, which will make them a better student.

Instructor since 2022
Tameem attended Mathnasium as a student for almost 5 years before becoming an Instructor. He recently graduated from Gloucester County Institute of Technology. During his years in high school, Tameem took Honors Geometry, Honors Algebra ll, Honors Pre-Calculus, Honors Physics, and doubled up on Honors and College Level Calculus during his senior year. He will attend Drexel University as a Pre-Med Biology major. Tameem discovered his love for math as a child. It was the one thing in school that he had looked forward to every day. As he grew older, he started to notice how much he was progressing compared to other students. He viewed math not only as a school subject but as a fun hobby. He was fascinated by how his brain could tackle complex math problems. Tameem enrolled in the Allied Health/Biomedical sciences program at GCIT, hoping to pursue a career in the medical field with his strong passion to help others. He was also a part of his school’s forensic sciences club and health professionals organization club. Tameem has been playing the guitar for 7 years and joined his school’s music/songwriting club. In his free time, he likes to draw, ride his skateboard, solve Rubik’s cubes and puzzles, play video games, and work out. During his time in elementary school, his parents enrolled him in Kumon, a tutoring service that helps kids with mathematics. After a few years of enrollment, he wasn’t quite satisfied with his progress at Kumon. Although he was succeeding in school and getting straight A's in math, he wanted more. He later stumbled across Mathnasium through some friends that also shared his love for math. His perspective of math changed after his first couple of months as a student at Mathnasium. Tameem thought that Kumon was lacking the passion and motivation for the students. However, Mathnasium gave him an opportunity to share his love for math with other students and instructors. Tameem believes that Mathnasium efficiently targets all struggles within a student’s mathematic ability through its customized student programs. Kumon may have improved his skill level in math, but Mathnasium has also taught him to have confidence in problem-solving. Mathnasium helps students understand that they are capable of mastering math; all it takes is a helping hand. He may not be a student anymore, but he continues to apply the Mathnasium Method in his own life to tackle problems from all perspectives. Tameem has made countless friendships and bonds with the instructors who today, work alongside him to encourage and enlighten all students to succeed and excel in math.

He is a key member of his school's FIRST Robotics Team, where he helps with programming and data analytics. He is also a member of his school's Model UN delegation. Adam discovered his love for math when he was just three years old. After watching his older sister using a calculator, he decided to use it, not knowing what any of the buttons did. At that moment, the calculator became his new favorite toy. He took it around wherever he went, and started to learn what some of the buttons did. He advanced very quickly, and in second grade, his teacher even let him help other students who were stuck on math problems. This is where his passion for teaching began. Because Adam has always helped his peers in math while being a math student himself, he was able to get a solid understanding of the student's perspective. Adam believes that Mathnasium fully embodies this spirit. He believes that by creating strong foundations, the Mathnasium Method uncovers the drive that every student has to learn, even if that drive might not have been visible at the start.
