Dr. Marcus Peter

Dr. Marcus Peter went from militant atheist to passionate preacher after encountering Christ in 2008. Initially preaching against Catholicism, his prayerful study of Scripture, theology, philosophy, and the Church Fathers—alongside Mary’s intercession—led him back to the Catholic Church in 2010.

Now a renowned Catholic speaker, biblical theologian, and author, Marcus has delivered over 10,000 dynamic talks worldwide. He hosts Ave Maria Radio’s international programs Ave Maria in the Afternoon and Unveiling the Covenants, regularly appearing on EWTN.

Dr. Peter is committed to presenting the Gospel and Catholic teachings with zeal, clarity, conviction, and full adherence to the Church’s Magisterium. He customizes each talk and presentation to meet the unique needs of his audience, working tirelessly to help you achieve your retreat or event objectives and, most importantly, to lead others into a closer, deeper, and ever more transformative personal covenant relationship with Jesus Christ.

Dr. Peter earned his doctorate in biblical studies from Pontifex University and is Director of Theology at Ave Maria Radio and the Kresta Institute. He lives in Ann Arbor, Michigan, with his wife Stephanie and their children.
