After a successful career as a college professor, researcher, and administrator, I started our company, ReasonIO (with my wife and partner, Andi Sciacca) in order to help people study and apply philosophy in public, practical, and professional contexts. I continue teaching philosophy, literature, religious studies, and humanities courses at the Milwaukee Institute of Art and Design.

I take difficult philosophical texts, thinkers, and topics, and make them accessible for everyday people. That's how philosophy gets traction and remains closely connected with real life! The work I do with ReasonIO includes online course development and teaching, public speaking, organizational and ethics consulting, tutorial sessions, development of philosophy content, and philosophical counseling.

My work and expertise covers a wide range of topics, thinkers, and texts in western philosophy, ranging through ancient, medieval, modern, and late modern periods. Among the schools, movements, and traditions I draw upon are Platonism, Aristotelianism, Stoicism, Patristic and Medieval Christian thought, Dialectical thought, Existentialism, Critical Theory, and Philosophy as a Way of Life.

From 2016 to 2022, I served as the Editor of Stoicism Today. I remain a member of the Modern Stoicism, ltd. team. I am also the producer of the Half Hour Hegel series, which is nearing its completion. I have authored one book (Reason Fulfilled By Revelation), edited two volumes (Stoicism Today Selected Essays, volume 3 and volume 4), and published dozens of articles, book chapters, and encyclopedia entries. Although I work in significant part outside of the academy, I remain actively engaged in research and scholarship.

In recent years, I have held a Research Residency at the Institute for Saint Anselm Studies, been a Visiting Scholar position at European Graduate School, and was a Charles Chesnutt Library Fellow. I am also an APPA-certified Philosophical Counselor.
