Heather Audesirk will return to the science department after first coming to the Upper School last spring.
Since last teaching, Audesirk has completed her single-subject teaching credential in chemistry at Asuza Pacific University.
Audesirk will teach Chemistry and Chemistry Honors in the upcoming year.
Before becoming a teacher, she was a tutor for the Harvey Mudd Academic Excellence program, which gave her experience working with young students.
“It’ll be nice to have [the students] have one set of classroom policies and procedures rather than those from like three different teachers, which I know was really rough on everyone last year,” Audesirk said. “I’m really excited to start fresh, have everyone from the beginning and be able to make sure that everything runs smoothly.”
