John ThornburgJohn Thornburg

John Thornburg is the Upper School Director. He has oversight over an experienced and well-educated faculty who prepare students in grades nine through 12 for the academic, spiritual and life challenges they will face at college and beyond. In addition to the rigorous academic curriculum, the Upper School program includes the unique-in-Cincinnati Science Research Institute, our signature Character Education program and opportunities for students to to shine in the arts, music and drama. Mr. Thornburg came to The Summit in 2015-16 after 29 years in education. He brings with him a passion to facilitate student growth in all facets of their lives. A student’s spiritual formation, coupled with an excellent educational program, is of utmost importance and guides his leadership. He firmly believes students reach their full potential when their education is combined with a faith-based system. 

Mr. Thornburg understands the importance of a life-changing, quality education. His past experience includes 20 years in the classroom as a biology teacher. During that time he not only led curriculum development, but conducted educational research, earning two masters’ degrees. His first area of research was in the development of critical thinking skills in science students. In this study he challenged students to understand how our faith is a compelling area to partner with science. The other area of study was in pedagogy that promotes a positive learning relationship between a teacher and a student. He interviewed and studied the dynamic of relational teaching at an all-boys boarding school. He has presented at several educational conferences on this topic and was published in Thymos: Journal of Boyhood Studies. Mr. Thornburg has also participated in research with the International Boys’ School Coalition (IBSC). He led research on the development of student relationships in a blended learning environment. In this study he “flipped” his biology classroom and required students to learn online outside the class day. The expectation was they would be prepared for further investigation and discussion when in the classroom. His findings were published under the auspices of the IBSC. He presented his research at an international conference.

Mr. Thornburg has a strong background in educational leadership, serving as Academic Dean and Vice President of an all-boys boarding school. In these roles he led a school-wide professional development initiative to develop a relational school model. He formed a partnership with Dr. Michael Reichert (co-author of Reaching Boys, Teaching Boys and I Can Learn from You: Boys as Relational Learners), Executive Director of The Center for the Study of Boys’ and Girls’ Lives. A new model of professional development was formed to support teachers in their growth as relational instructors. Along with his teaching experience, he served as a head cross country and track coach for more than 20 years. He views athletics as a key component in maintaining student health and providing the balance for the demands of being a successful student. 

He has a bachelor's degree in biology from the University of Wisconsin-LaCrosse, a master's degree in teaching from the University of Wisconsin-Whitewater and a master's in educational leadership from Marian University. He received the Roy F. Farrand Teaching in Excellence Award in 1992 and Honorary Alumnus Award from St. John's Northwestern Military Academy in 2003.
