Faculty & Staff Directory
Mary Plant-Thomas is excited to begin her third year as part of Gateway High School's Science Department, teaching Biology 10 and AP Biology. Mary earned her undergraduate degree from an unconventional combination of Wellesley College and UC San Diego. She then went on to get her Masters in Education from UC Santa Barbara's Teacher Education Program where she was a Noyce Scholar. While at UCSB, Mary was able to participate in an international exchange that enabled her to observe another education system by student-teaching in Denmark! In addition to loving teaching and science (especially biology), Mary has a passion for theatre and can frequently be found rushing off to see plays all around the Bay Area.
