Senior Leadership

David Breeckner
Executive Director
A passion for history and learning. These traits define Dr. David Breeckner, and describe a career spanning the fields of archaeology, college lecturing, public history, and museum management. A transplant from New England, Dr. Breeckner received his Masters and Doctorate in Classical Archaeology at Trinity College Dublin in Dublin, Ireland. Since 2011, Dr. Breeckner has served as ceramic archaeologist with the Priniatikos Pyrgos Project, an Irish-led excavation based on the Mediterranean island of Crete. There, he specialized in the study of the enigmatic Minoan civilization of the Greek Bronze Age. His work with the Project demonstrated the transformative nature of interacting with history: that the sensation of studying and handling artifacts was in fact a conversation — one that bridges the present with the countless lives and stories of the past, and makes it come alive. This philosophy now drives Dr. Breeckner in all his endeavors. An educator, Dr. Breeckner has served as a member of faculty in various state universities, where his courses covered historical subjects and civilizations from prehistory through to the Renaissance. His time with students has refined a pedagogy focused around deep engagement, with the goal to reveal the relevancy of the past and to inspire meaningful connections between students and their subject. He believes that history belongs to the communities they represent, and that its study can provide new meaning and value to our present and future. David is thrilled to share his experience-based way of learning and a forward-looking vision for the future with the people of Arizona, joining AHS with his wife Leslye and their two dogs, Brandy and Akira.
