Background: William earned dual bachelor's degrees in mathematics and economics from the University of California, Los Angeles in 2005 and a master's degree in education from Loyola Marymount University in 2007. He has been working in schools as a teacher and administrator at the middle and high school levels since 2005.
One of William's greatest joys from teaching is cultivating in students a growth mindset and a genuine love for mathematical problem solving. His former students have competed at the highest levels at the MathCounts and American Math Competition competitions. Outside of teaching, William enjoys reading at Starbucks, playing tennis and ping-pong, and hiking local trails with his family.
