Marcellino D’Ambrosio, Ph.D.
The Crossroads Initiative


Raised in Italian/Irish neighborhood in Providence, RI, Marcellino D’Ambrosio never thought about being anything else but Catholic. But like other Catholic teens, his faith was the last place he looked for fulfillment. Following in the footsteps of his parents, both professional performers, Marcellino set his sights on stardom, playing bass guitar in several popular rock bands by the time he was 16. At that time he encountered a group of Catholics whose Christian life was an exciting adventure, an adventure worth living for. So he laid his bass guitar aside and embarked on a road that led to a Ph.D. in historical theology from the Catholic University of America. His doctoral dissertation, written under the direction of the renowned Jesuit theologian, Avery Cardinal Dulles, focused on one of the theological lights of the Second Vatican Council, Henri Cardinal de Lubac, and his recovery of biblical interpretation of the early Church fathers.

Dr. D’Ambrosio’s academic teaching at Loyola and the University of Dallas covered a broad range of subjects from historical and sacramental theology to the new evangelization, ecumenism, and Vatican II. Yet throughout his academic career, Dr. D’Ambrosio remained deeply involved in pastoral work, especially teen evangelization and Hispanic ministry, assuring that his teaching remained relevant to the challenges of everyday life.

His writing has been published in numerous Catholic publications such as Our Sunday Visitor and Catholic News Service’s syndicated column "Faith Alive." His popular book, Exploring the Catholic Church and video courseby the same name (known as Touching Jesus through the Church in the USA) have been used in hundreds of parishes all throughout the English speaking world. Dr. D'Ambrosio is a New York Times best-selling author with his Guide to the Passion: 100 Questions about the Passion of the Christ ranking among the fastest-selling Catholic book of all time with over a million copies sold in less than three months.

Dr. D’Ambrosio, the father of five and a business owner, brings to his teaching a practical, down-to-earth perspective that makes his words easy to understand and put into practice. Audio and videorecordings of his popular teaching are internationally distributed. He often appears on the international Eternal Word Television Network is regularly heard on nationally syndicated radio shows such as "Catholic Answers Live." Dr. D'Ambrosio has been repeatedly called upon to serve as an expert commentator on religious and moral issues for Fox News Geraldo Rivera, At Large and Bill O'Reilly's radio show.

In 2001 Dr. D’Ambrosio left his position at the University of Dallas to develop the work of Crossroads Productions, the apostolate of Catholic renewal and evangelization that he co-founded twenty years ago, and to more directly oversee the growth of Wellness Opportunities Group a company dedicated to helping people improve the quality of their lives physically, mentally, and financially. He, his wife Susan, and their five children, reside just outside of Dallas, TX.
