"The Christian life is a person-to-person transforming encounter—betwixt believers and Christ, among believers, and with all the peoples of the world. The Christian gospel is not only an ancient and growing body of doctrine. It is also a transforming set of practices and a call to virtue, always in context, always personal and formational, and all for the common good in the Reign of God.” 

The road that brought me to ministry at Aquinas Institute of Theology involved almost twenty years of pastoral ministry at the Catholic Campus Parish of South Dakota State University, Brookings, South Dakota; Associate Pastor at Blessed Sacrament Parish, Madison, Wisconsin; Vocation Coordinator for the Dominican Central Province, Chicago, Illinois; priest for the St. Giles Family Mass Community, Oak Park, Illinois; and chaplain for Dominican Chapel/Marywood and founder and program director for Dominican Center at Marywood in Grand Rapids, Michigan. After completing my Doctor of Ministry in Preaching in 1991, I came to Aquinas Institute in 1994 to live in the formation community of Saint Dominic Priory and to serve as Director of Field Education and Assistant Professor of Homiletics. Now, a surprising twenty years later, I continue to serve as Professor of Homiletics, while serving also since 2007 as Academic Dean and Vice President. I now reside at Saint Louis Bertrand House near Forest Park.

My academic interests have to do with the theology of preaching, Christian healing, and evangelization —with a particular and longstanding interest in repairing the fractured relationship of men and women in our culture (Galatians 3:28).

I continue to take any opportunity I can to hike in the American West. Favorite places include Mount Rainier National Park in Washington, Zion National Park in Utah, Yellowstone National Park in Wyoming, and the Big Sur Coast in California. My most recent hikes have taken me to Mount Rainier and Yellowstone.
