Last, but not least, she is committed to contributing to the development of excellent online literacy learning at ACS Athens.

Ms. Tsinakis is committed to fostering, inspiring, and sustaining high levels of authentic learning in all students as a path through which they become active, compassionate, independent, and global learners.
