In her previous schools, she worked in teams to vertically and horizontally align these school-wide outcomes across subject areas and mentored new teachers on these approaches. She has also attended PD at The National Coalition for English Teachers, BluePrint for the Moving Image, and PBL World, and presented at conferences such as The NYC Writing Project, the International Coalition of Girls’ Schools, & Competency Collaborative’s Summer Institutes.

Ms. Thomopoulos is incredibly passionate about blending the traditional with the innovative and in creating nurturing spaces for self-advocacy. It is here where educators can act as facilitators to guide students to become independent, yet conscious thinkers, ethically minded global citizens, and compassionate risk-takers. She is, thus, thrilled and honored to join the ACS team where this environment already exists and excited to see what is to come.
