Center Director/OwnerScott Rubin, Center Director/Owner

Scott received his Bachelors in Finance from the State University of New York College at Buffalo. He then received his MBA in Management from Pace University. He has worked as a financial analyst on wall street with JPMorgan and other finance companies until he moved to Marin County. Scott has always had a passion for math. Starting at a young age he was constantly coming up with creative ways to solve math problems. In order to give back to the community he tutored math voluntarily at a high school in NYC. Scott enjoyed tutoring so much that he looked into changing careers and that is when he found Mathnasium, a perfect fit. Scott, his wife Christine and their maltipoo Mylos moved to Marin County in Jun 2012 to start a new life. The original plan was to open up a Mathnasium in or near NYC, but after visiting relatives in Tiburon they decided that was the place for them. Since then, Scott delayed opening his Mathnasium for a year in order to prepare for the big move. He spent that time tutoring at other Mathnasium's and spending 100's of hours learning the Mathnasium Method. Scott is a Mathnasium master certified center director. Someone who is master certified has received the highest certification level Mathnasium offers.
