Welcome to the website. I am the pastor of our three Catholic parishes in Kingsbury County, South Dakota. The parishes are: St. Thomas Aquinas in De Smet, where I reside; St. Paul the Apostle in Iroquois; St. John the Evangelist in Arlington.

If you are a parishioner of one of our parishes, I hope you will find the information on our website helpful in keeping informed about our spiritual journey as part of the Family of God.  If you are visiting this site, I hope you will receive a good idea about what it is to be a strong, vibrant Catholic community. I believe the pages of the website are clear enough for you to sort through.   May God bless you in your spiritual journey. The "Blog" tab has important information from the parish and the diocese.

You will find information about the parishes by clicking the "Contact" tab.
