David Hajduk, Ph.D., has more than thirty years of experience in religious education and pastoral ministry, including youth, family life, and pro-life ministries. He did his doctoral work in Theology at Maryvale Institute in Birmingham, England, and wrote his dissertation on the thought of St. John Paul II. Since 1998, he has been a member of the Theology Department at Delbarton School in Morristown, NJ, and has served as an Adjunct Professor of Moral Theology at Immaculate Conception Seminary School of Theology at Seton Hall University since 2008, teaching courses on John Paul II’s Theology of the Body and sexual ethics, and on the Theology and Spirituality of Marriage & Family. In 2019, Hajduk became the Director of Theology for Array of Hope, a ministry of the New Evangelization that shares the beauty and truth of the Catholic faith through high quality media and events. He is responsible for reviewing and creating program content, writing blogs, and giving talks. Hajduk is the co-producer of Array of Hope’s A Reason for Hope podcast, featuring interviews with renowned Catholic personalities, and segments unpacking the truths of the Catholic Faith. 

Hajduk is an acclaimed and versatile speaker, having given keynote addresses at conferences, presentations to high schools and colleges, parish talks to both youth and adult audiences, and 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.” Hajduk 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.” 

David resides in Belvidere, NJ. He and his wife, Shannon, have 11 children and homeschool.
