Dr. David Tamisiea is the Dean of the School of Arts and Sciences at the University of Mary and an Associate Professor of Theology. Prior to his tenure as dean, Tamisiea served as the Administrative Chair of University-Wide Programs at Mary.

Tamisiea’s doctoral work focused on the baptismal priesthood of the Christian lay faithful and its relation to the Eucharist, and his master’s thesis examined the Catholic idea of a living tradition.

Prior to his graduate studies in theology, Tamisiea was a practicing attorney in the Dallas-Fort Worth area for over 10 years, specializing in civil litigation. He holds the degrees of BA from the University of Notre Dame, JD from the University of Texas at Austin, and MA and PhD in theology from Ave Maria University.

Tamisiea is deeply committed to his Catholic faith, loves spending time with his family, is an avid learner, a voracious reader, and enjoys fitness activities and watching sports in his spare time.
