Teacher Profile
Unlocking the
Power of Education
Diana Martelly, Head of High School, Mathematics
Teacher & Student Extraordinaire
Diana Martelly is a dreamer, a trailblazer and a lifelong learner. At the age of 50,
as she hungered for more, she resumed her personal education. Admitted to both
Harvard and Columbia Universities, she enrolled in the latter where she received
a degree in educational leadership. To her students, she is an inclusive teacher
and role model while her faculty appreciates Dr. Martelly’s balanced leadership
style and accessibility. Relishing in the prospect of seeing off Keystone’s first
graduating cohort, Dr. Martelly’s vision for our seniors is to pursue personal
success and take up responsibility to make the world a better place. She steadfastly
believes that we all have the potential to change the world... “You can, if you choose
to” is one of her mantras.
