How do I find Mass times or a parish near me?
We have over 50 parishes and missions across Eastern Montana. You can use our interactive Parish Finder Tool to search by city, zip code, or specific liturgy options like language or Adoration.
How do I register as a parishioner?
Parish registration is handled at the local level. Once you find your spiritual home using our Parish Finder, please reach out to that specific parish office directly to register your family.

Congratulations! The first step is to contact your local parish priest at least six months prior to your anticipated wedding date. He will guide you through the marriage preparation process and the necessary paperwork.
