He has a Bachelor’s degree from the University of California, San Diego in Psychology with a minor in Biology and Chemistry.

Sulu’s realization of the importance of math as an entrepreneur has given him insight into how kids struggle with math but do not have to.

Now he is devoted to teaching math in a way that makes sense to them, and he is committed to bringing the Mathnasium Method to the children in the community.
