Owner/Center Director
My name is Gabbi and I am the owner and center director at Mathnasium of Flemington. I make it my goal to ensure that students have an effective, engaging and encouraging learning experience that cultivates an intuitive understanding of math. I do this by selecting highly trained instructors who are passionate about math, maintain the best environment for learning and always stay positive. As a former math teacher with my Masters of Education, I have experience with many different curriculums and Mathnasium's learning plans are curated in a way to make math make sense to every student at their level. At Mathnasium, we offer the tools to help young learners improve critical math skills and understanding. Please feel free to reach out to me with any questions.
