Dr. Bryan Thatcher

September 23, 2026

Dr. Bryan Thatcher is a retired medical doctor from Tampa, Florida, who widely known as the founder of the Eucharistic Apostles of The Divine Mercy (EADM).

EADM is a prominent lay apostolate of the Congregation of Marian Fathers of the Immaculate Conception. After experiencing a profound personal conversion 30 years ago through the diary of Saint Faustina, Dr. Thatcher pivoted his career from performing surgeries to spreading the message of Catholic Divine Mercy worldwide. He authored a popular series of three manuals used globally by small faith-sharing groups to study Saint Faustina’s diary alongside Sacred Scripture and the Catechism.

His global ministry has received three personally signed Apostolic Blessings from Pope St. John Paul II. Beyond prayer, his ministry coordinates the shipment of medical and educational supplies to impoverished areas, including severe outreach efforts in the Philippines.

He hosts the popular podcast and video series Mercy Unbound, which discusses living a sacramental life, trust, forgiveness, and carrying life’s crosses. He hosted the “Cenacle of The Divine Mercy” and “The Healing of Addictions Through the Message of Divine Mercy” on the EWTN global Catholic network.

Dr. Thatcher heavily preaches that Divine Mercy is not just a collection of prayers or a simple devotion, but rather an active “Way of Life.” He emphasizes that true devotion requires experiencing God’s love, forgiving oneself and others, and physically acting out works of mercy to lessen the misery of those around you.
