Father Pacholczyk grew up in Tucson, Arizona. His father Andrzej Pacholczyk was a professor of astrophysics at the University of Arizona. He earned his doctorate in neuroscience from Yale University and did post-doctoral studies at Harvard University.

In 1999, he was ordained a priest in Rome. He quickly became the leading church spokesman on what he calls beginning-of-life and end-of-life issues. He's been an outspoken proponent of the Catholic Church's positions on human cloning and embryonic stem cell research, positions which recognize the inherent dignity of the human person from the moment of conception and which oppose the deliberate taking of innocent human life. (See Declaration on the Production and the Scientific and Therapeutic Use of Human Embryonic Stem Cells.) In December 2001, he testified before the Massachusetts Senate that "embryonic human life is inviolable and deserving of unconditional respect."

Pacholczyk is currently a priest of the diocese of Fall River, Massachusetts and he writes a monthly column for The Catholic Herald called, "Making Sense Out of Bioethics," which gets reprinted nationally in many local church newspapers. He also serves as the director of education at The National Catholic Bioethics Center in Philadelphia, whose director, John Haas, is an ordinary member of the Pontifical Academy For Life.
