When I visited I discovered the Mission was closed for a Private Mass - how do you arrange a Private Mass?

I would suggest calling the number listed.

They had one for my dad he grew up in Bergsmill and made his first communion at San Juan his funeral was held there also so maybe you have to be tied into the church. Talk to the priest he's super nice

Give the mission a call.

You would have to call the parish office and not the Park Service.

There's no mass there

The best way you can make arrangements for private mass. Call to the mission directly or in person if you want in the office locates at the mission.

You can arrange it by calling them directly

Weddings, baptismal.
