Peter Kwasniewski (pronounced, at least in America, as Quash-NEV-ski), born in Chicago in 1971, spent his youth in New Jersey, where attendance at an all-boys Catholic high school brought him an exceptional training in humanities and poor to non-existent religious instruction.

He went off to Georgetown University for a single year, after which he made one of the best moves of his life by starting over again at Thomas Aquinas College in California, from which he received a B.A. in Liberal Arts in 1994. Not having had his fill of Washington, D.C., he earned an M.A. and a Ph.D. in Philosophy from The Catholic University of America, whose giant statue of Pope Leo XIII in McMahon Hall was a beneficent presence throughout.

After teaching philosophy and theology at the International Theological Institute in Austria and music for the Franciscan University of Steubenville’s Austrian Program (1998–2006), he joined the founding team of Wyoming Catholic College in Lander, Wyoming, where he served as the first Director of Admissions and Assistant Academic Dean, directed the Choir and Schola, and taught, over time, all of the theology courses and most of the philosophy and fine arts courses (2006–2018). He left WCC in the summer of 2018 to pursue a career as a freelance author, public speaker, editor, publisher, and composer, with the intention of dedicating his life to the articulation and defense of Catholic Tradition in all its dimensions.

Over the past twenty years, Kwasniewski has published over 1,300 articles, both academic and popular, on sacramental and liturgical theology, the aesthetics of music, Thomistic thought, and the social doctrine of the Church. His articles have been translated into at least 18 languages.

He has written or edited twenty books: Wisdom’s Apprentice (CUA Press, 2007); On Love and Charity: Readings from Aquinas's Commentary on the Sentences (CUA Press, 2008); Sacred Choral Works (Corpus Christi Watershed, 2014); Resurgent in the Midst of Crisis: Sacred Liturgy, the Traditional Latin Mass, and Renewal in the Church (Angelico Press, 2014); Noble Beauty, Transcendent Holiness: Why the Modern Age Needs the Mass of Ages (Angelico Press, 2017), A Reader in Catholic Social Teaching: From Syllabus Errorum to Deus Caritas Est (Cluny Media, 2017); Tradition and Sanity: Conversations and Dialogues of a Postconciliar Exile (Angelico, 2018); John Henry Newman on Worship, Reverence, and Ritual (Os Justi, 2019); And Rightly So: Selected Letters and Articles of Neil McCaffrey (Roman Catholic Books, 2019); Reclaiming Our Roman Catholic Birthright: The Genius and Timeliness of the Traditional Latin Mass (Angelico Press, 2020); The Holy Bread of Eternal Life: Restoring Eucharistic Reverence in an Age of Impiety (Sophia, 2020); The Ecstasy of Love in the Thought of Thomas Aquinas (Emmaus Academic, 2021); Ministers of Christ: Recovering the Roles of Clergy and Laity in an Age of Confusion (Sophia, 2021); True Obedience in the Church: A Guide to Discernment in Challenging Times (Sophia, 2021); Are Canonizations Infallible?

(Arouca, 2022); The Once and Future Roman Rite: Returning to the Traditional Latin Liturgy after Seventy Years of Exile (TAN Books, forthcoming in 2022). Several of these books have been or are being translated into other languages. 

Dr. Kwasniewski writes regularly for New Liturgical Movement, OnePeterFive, LifeSiteNewsRorate Caeli, The Remnant, Catholic Family News, and The Latin Mass magazine.

Many of his approximately 150 musical works have been performed in liturgical settings and in concert.

Kwasniewski has also worked with The Aquinas Institute that is editing and publishing the Opera Omnia of the Angelic Doctor in some 60 volumes. He is a Fellow of the Albertus Magnus Center for Scholastic Studies and a Senior Fellow of the St. Paul Center in Steubenville.
