Welcome

Tina Santilli 

HS Principal

Now in her second year as High School Principal, Tina Santilli brings more than 25 years in international education to ICS, including service as a Head of School, Deputy Head of School, and Principal. She recently completed her Doctor of Education (EdD) in Transformative Leadership at Bay Path University.

Tina is happiest in the middle of school life — in classrooms, at games and performances, and in conversation with students and families. She would always rather hear from you early than late, so please stop her in the corridor and introduce yourself.

Beyond school, Tina dives, kayaks, reads widely, and never turns down a safari or the chance to explore somewhere new and get to know the community around her.

Steve Melville

HS Deputy Principal

With a heart for Africa and its people, Steve has spent 21 years leading and learning in diverse communities from Cape to Cairo. 

As an educator, Steve is passionate about mentoring young adults, offering them encouragement and celebrating their progress. He believes strongly in the power of partnership, responsible inclusion and the need to laugh often and heartily. Steve is an amateur futurist who admires novel ideas and approaches, though not when it comes to trying new foods.

With family and friends, he enjoys any game with a ball in it, brainteasers, science fiction and exploring back roads with equally inquisitive travelers. Steve is married to Desiree who is also a teacher and they have two sons, Josh and Zac.
