Executive Director

Darryl De Marzio, Ph.D.

Born and raised in Paterson, New Jersey, Dr. De Marzio attended Blair Academy as a boarding student where he played varsity baseball, junior varsity basketball, and performed in several theatre productions. It was at Blair that he developed a genuine passion for learning and critical thinking, and a true appreciation for the boarding school experience. He graduated from Drew University, having majored in philosophy with a minor in religion. After graduating from Drew, he completed an M.A. in Elementary Education at Montclair State University and began working at the Institute for the Advancement of Philosophy for Children at Montclair as their Director of Field Services, helping to develop and implement philosophy programming in K-12 schools throughout the United States.

These formative experiences led Dr. De Marzio to pursue graduate research that connected the academic discipline of philosophy with educational practice. He completed his M.Phil. and Ph.D. degrees at Columbia University with a scholarly focus on the role that the study of philosophy plays in the formation and training of teachers. He was awarded the Merryman Prize for excellence in the graduate study of philosophy and education and his dissertation, The Teacher as Ethical Subject, was awarded distinction by the Graduate School of Arts and Sciences at Columbia University. Since graduating in 2007, he has returned to Columbia every summer to teach a graduate seminar on vocation and professional ethics.

Dr. De Marzio joined the faculty of the University of Scranton as Professor of the Foundations of Education, where he taught courses in philosophy and educational theory for fifteen years. He also served terms as Chair of the Education Department and as Director of Undergraduate Programs. During his time at Scranton, he published dozens of articles in leading academic journals of philosophy and educational research, edited two books, and served as president of the Middle Atlantic States Philosophy of Education Society. For several years, he was also the host and producer of a popular radio show in Scranton which highlighted the musical legacy of the Grateful Dead.

Prior to arriving at Portsmouth Abbey School, Dr. De Marzio lived with his wife, Anne, and three children on the campus of Wyoming Seminary, the boarding school where Anne taught English for eight years. This time rekindled his love for boarding school life, and he could not be more excited and honored to join the mission-driven community here at Portsmouth Abbey School. For him, the study of the great works in the humanities is an invitation for students to become full-fledged participants in the ongoing conversation about the human condition and the human prospect, and to explore what it means to be made in the image of God.
