St. Ignatius Parish and School is located in the small rural farming community of Concord Hill - just outside of Marthasville, in Warren County, Missouri.  Part of the St Louis Archdiocese, St. Ignatius is a growing parish with a long history of community involvement. In addition to worshiping together at Sunday and daily Masses, parishioners enjoy socializing at parish-sponsored events, such as our annual Thanksgiving Day Dinner Auction, just to name a few.
