The Fathers of Mercy is a Roman Catholic Congregation of Priests who are focused on preaching to parish missions and retreats. Founded in France in 1808, the Fathers of Mercy have a strong emphasis on the Sacraments of the Holy Eucharist and Confession.
Since 2011, at the request of the Bishop of Green Bay, The Fathers of Mercy have staffed the National Shrine of Our Lady of Good Help and served its pilgrims through the Sacraments. Rev. Joseph Aytona, C.P.M, serves as the Rector of the Shrine, with Fr. Thomas Reagan, C.P.M., and Fr. Michael French, C.P.M., serving as Chaplains.
