My name is Fr. Daniel Sedlacek (pronounced: “Sed–LAH–check”). I grew up on my parents’ dairy farm just outside of Cornell, Wisconsin, with my three brothers and five sisters. My K-12 education was all at home. The Catholic Faith and working together on the family farm were the primary facets of my family’s life. One of my favorite things to do while growing up was to serve Mass at my home parish of Holy Cross.   I first experienced God’s call to the priesthood when I was in fifth grade, when I read a book about the life of St. Francis Xavier, one of the greatest missionaries in the entire history of Christianity. There were many other small “signs” and “hints” that God was calling me to the priesthood, although it took me some years to recognize those signs and even more time to accept His summons. With God’s grace and the intervention of a youth minister, I decided to enter seminary right after graduation from high school.   I attended St. John Vianney College Seminary at the University of St. Thomas in St. Paul, Minnesota for my first four years of philosophy studies and then was sent to study theology for four years in Rome, Italy. I was ordained ordained a priest at the Cathedral in La Crosse on June 25, 2016.   Before coming to Aquinas High School, I was the associate pastor at St. John the Baptist parish in Marshfield and Christ the King parish in Spencer, and the chaplain to Columbus Catholic High School and Middle School in Marshfield from 2016-2018. From 2018-2020 I was the associate pastor at St. Mary's parish in Altoona and St. Raymond's parish in Fall Creek and the chaplain at Regis HS and MS in Eau Claire. I am currently the Aquinas High School Chaplain as well as pastor at St. Charles Borromeo parish and school in Genoa. I give thanks to God for summoning me into a friendship with Jesus Christ and for calling me to the priesthood and now for sending me to Genoa and Aquinas Catholic Schools.
