Todd Velianski, Center Director

Todd is friends with three leprechauns. Well... he knows three people who were the mascots for the Fightin' Irish of the University of Notre Dame, where he earned his BA after graduating from Phillipsburg High School. He also earned his master's degree from Boston College. Todd has been an instructor using the Mathnasium Method since February 2017. His students know him for his quirky sense of humor and his insistence on learning the Latin and Greek roots of mathematical terms. Todd is hands-on and still instructs higher level math. While math is Todd's favorite language, he enjoys studying foreign languages in his free time. He also loves physical fitness, boxing, and blaring 90s music that the kids these days call "old."
