Fr. Amann served as assistant pastor at St. Andrews, Rochester (1954-58), and Holy Trinity Webster, (1958-62), before becoming the first chaplain at Bishop Kearney High School (1962-65). He was assistant pastor (1965), copastor (1974-78) and pastor (1978-81) of Our Lady of Mercy in Greece, NY. He then served as administrator at St. Cecelia parish in Elmira for several months, before taking a sabbatical in Rome to study changes in the church post-Vatican II. After returning to the US in 1982, he helped found St. Elizabeth Ann Seton church (SEAS) in Hamlin, NY, which was one of his favorite experiences. Fr. Amann always gave the credit for the founding of SEAS to his parishioners. In 1990, Fr. Amann took another sabbatical, this time to Africa, to study enculturation and liberation theology. Upon retiring from the pastorate at SEAS in 1998, he lived and ministered at Our Lady of Lourdes (1998-2001) and St. Thomas More (2001-2009) in Brighton, and St. Joseph’s in Penfield (2009-2018). Fr.
