A Unique International Faculty

Like its student body, the Institute's faculty is diverse and international, bringing together professors from the United States, Germany, Austria, Lithuania, England, and other countries. The faculty to student ratio is deliberately small, with an average ratio of 1:12. This enables the students to engage in fruitful discussion about the classic texts they study together with their peers and professors.

Outside of class it is typical for the professors and their families to mingle socially with the students – at Mass, at dinners or parties, and on special occasions  – which fosters long-term friendships united around great common goods.
