and events. David is responsible for reviewing and creating program content, writing blogs, and

the Catholic Faith. 

David is an acclaimed speaker, having given keynote addresses at conferences, presentations to
high schools and colleges, and parish talks to both youth and adult audiences, as well as having
led diocesan training workshops and marriage preparation catechetical days. He specializes in
topics related to the sanctity of life and marriage, theological anthropology, and the philosophical
and theological foundations of the contemporary “crisis of truth.” David is the author of God’s
Plan for You: Life, Love, Marriage & Sex (Pauline Books & Media, 2006, 2018), a book for
teens on St. John Paul II’s Theology of the Body which received the Catholic Press Association
of the United States & Canada Book Award in 2007, and Healing the Culture and the Family
according to John Paul II (Arouca Press, 2022), an academic work demonstrating how John Paul
II’s theological anthropology was constructed to remedy a collection of errors of Cartesian
Rationalism John Paul II referred to as a “New Manichaeism.” Healing the Culture and the
Family has been endorsed by a list of internationally recognized theologians, among them world-
renown scholars of John Paul II’s work: Dr. John Grabowski, Dr. Jaroslaw Kupczak, O.P., and
Dr. Deborah Savage (who wrote the foreword).
David resides in Belvidere, New Jersey. He and his wife, Shannon, have 11 children and
