Brian joined the staff of Trinity Weekday School in 2021 and is currently a teacher in our Threes classroom.

After returning to college, Brian earned his teaching degree and certification from California University of Pennsylvania in 2017. He has worked in every grade level from elementary schools to preschools. Brian lives in Peter’s Township with his wife, Amye, their children, dogs, and cat.
