• Welcome! My name is Rebecca Petersheim, and the 2020-2021 school year will be my eighth year with the district. After graduating from CASHS in 2009, I attended Penn State University and graduated in 2013 with a degree in Secondary Education, English and Communications. In the fall of 2013, I returned to CASHS, and over the span of five years taught English 11, Creative Writing, English 10, and I advised the CASHS Echo Yearbook. For the last two years, I was an Instructional Coach, working with teachers and students to instill best instructional practices to promote student learning.

    This year, I am returning to the classroom to teach English 10 and Creative Writing, and I am excited to make this year a great one! If you have any questions, comments, or concerns, please e-maiil me at rebecca.petersheim@casdonline.org.
