The Ursuline Experience of Montana Missions

Ursuline Retreat and Conference Centre in Great Falls, Montana

This trip includes a full schedule of historic presentations, service outreach, excursions, learning about native peoples' spirituality, field trips, and Ursuline mission visits. It is open to all Ursuline Sisters, Associates, administrators, teachers, and parents, as well as college, rising junior and senior high school students, mother/daughter combos, as well as others connected to UA.

The next Mission Trip date is TBD due to COVID-19.


The Montana Experience, "Where Angela Has Led Us," is an interesting and engaging program about Ursuline Foundations in Montana, Native American Culture, the Lewis & Clark Expedition and more.

The Ursuline Centre, which is on the National Register of Historic Places, was opened in 1912 as a K-12 school for boarders and day students. It contains many pieces of artwork, Native American artifacts, antiques, and memorabilia in the rooms and along the hallways. The week-long program includes excursions to several Ursuline sites in Montana, including an all-day trip to the Fort Belknap Indian reservation and St. Paul Mission. This former Ursuline Mission, where members of the Gros Ventre and Assiniboine Tribes still reside, remains active.

There are also opportunities to view the Missouri River Breaks and some of the country that Lewis and Clark experienced. Other trips include an all-day venture to St. Ignatius, Montana, where Mother Amadeus is buried, and an afternoon trip to the historic St. Peter’s Mission, established in the wilds of Montana by Mother Amadeus in 1884. Afternoon visits to the Lewis & Clark Interpretive Center, First Peoples Buffalo Jump, and the Big Stone Hutterite Colony are also scheduled.

It is highly recommended that participants read the book Lady Blackrobes, a history of the Ursuline Missions in the heart of Indian country, written by Sr. Irene Mahoney. To order the book, contact Sr. Francis Porter at (406) 452-8585 or email the Centre at

Diocesan Mission Trips

Student missionaries participate in large-scale mission outreach through this annual high school mission trip program, organized by the Office of Pastoral Services in the Diocese of Dallas. Ursuline students travel on these mission trips with students from other Catholic schools in the Diocese.

These trips offer a unique opportunity to share, learn, and cultivate friendships with students from peer-school communities.

In recent years, Diocesan high school mission delegations have traveled to Belize, Nicaragua (2013-2017), Argentina, and Costa Rica. Student missioners are accompanied by chaperones, usually faculty and staff from participating schools, and provided with a safe, yet profound opportunity to encounter true poverty and engage in opportunities for spiritual and personal growth.

Going to Belize and being surrounded with people who emulate Christ so obviously changed me immensely. They are inspiring in their faith and joy concerning the life they were given. It moved me greatly and I would not trade this experience for the world!
