Math teacher Bill Thill will depart at the end of this year and work as the math department head at the Episcopal School of Los Angeles.

At his new school, Thill will be leading his colleagues in restructuring their existing program.

“[My new position] is a great opportunity to utilize the things I’ve learned in terms of leadership,” Thill said. “I’ll be working with teachers and thinking on a big picture level about curriculums that help kids grow their mathematical understanding and knowledge through questioning and independent work.”

Thill has worked at the Upper School for 18 years and has taught courses ranging from Multivariable Calculus to Sports Research. He currently teaches Algebra II with Analysis, AP Statistics and Computer Science Principles.

“Harvard-Westlake provides lots of ways to grow professionally,” Thill said. “The amount of opportunity that a place like this affords you is amazing, and I’m very appreciative of it. Here, I love being able to socialize and see students and colleagues outside the classroom. I cherish them.”

Thill has already begun his transition to the Episcopal School of Los Angeles.

This spring, he started working with his colleagues at his new school in order to develop a better understanding of the school’s dynamic.
