Past Speakers

In order to ensure that our students never lose sight of the different reality that so many others in the world experience on a daily basis, we feel it is important to expose them to first hand testimony from people with personal stories that challenge their world view.

Talks have so far covered topics as diverse and wide ranging as environmental issues, race relations, human and civil rights, conflict and reconciliation, science, the problem of homelessness and even Ancient Greek philosophy! 

Desirous to safeguard the important lessons they learned during their exchanges with our guest speakers, students journalists actively engaged with their campus newspapers have interviewed many of the speakers and preserved their important lessons for future generations of students.
