Hong Yu

In-Person/ Online Instructor
Hong has an impressive background in Aerospace Engineering and brings over a decade of tutoring experience to our center. Before joining Mathnasium, most of his tutoring experience was done at the college level. Hong admits that he felt slightly nervous when he first joined our team, not having much experience working with younger students. However, he sees how our teaching techniques really get students to understand math in a way that actually makes sense. Hong still dreams of becoming an Aerospace Engineer, where one day he will be building spaceships and designing technology to explore the vastness of outer space. When he is not teaching (or dreaming), he stays relatively grounded by reading non-fiction materials on science, engineering, and aviation. He also likes to keep up with sports and current events.
