Religious Staff


Immaculate Conception Church is serviced by priests from the Society of St. Pius X. They reside in the priory, located in close proximity to the church.

Daily Mass is offered in Post Falls and Spokane Valley by these priests (See our schedule for more details). By their constant presence they ensure the availability of the sacraments at all times.

On the weekends some of them travel to say Mass at various Mass centers throughout the Northwest. During the week they teach at our boys school and a girls school run by Dominican teaching sisters.
