Sister Erin in pink on the celebration of her silver jubilee.


Each day of Catholic Sisters Week, we will be sharing the stories of our Jubiliarian Sisters, celebrating a significant anniversary in religious life of 25 and 50 YEARS of service to Christ, Church, and Community…

Join us in praying for Catholic Sisters and Nuns who continue to seek God’s Will and serve God’s people throughout our nation.  Pray also for women who continue to discern God’s will in their lives.

Sister Erin is the second of four children born to James and Alice Colgan, growing up on an acreage near North Bend, NE, graduating from North Bend Central Jr.-Sr. High School and Wayne State College, Wayne, NE. While working at the University of Nebraska Foundation in Lincoln, she was introduced to the Yankton Benedictine Sisters. The influence of friends, involvement in the Newman Club during college, a weekend experience with the Missionary Benedictine Sisters in Norfolk, NE, retreats in college and beyond, as well as making a Monastic Experience with the Yankton Benedictines, helped her to discern a vocation to religious life. At the time she entered community, our Sisters prayed morning, noon, and evening Liturgy of the Hours in small groups of 8-15 women. “It was in this setting that I gained an appreciation for the diversity of the Psalms and the Sisters, as well as the simplicity of monastic life.

After her first monastic profession on August 7, 1994, she worked in the Registrar’s Office at Mount Marty College, helping to implement a new administrative computer system. Sr. Erin made final monastic profession August 2, 1997. After ten years in the Registrar’s Office, she attended law school. She chose the one whose mission statement spoke to her heart. “The University of St. Thomas School of Law, as a Catholic law school, is dedicated to integrating faith and reason in the search for truth through a focus on morality and social justice.”  After graduating in 2007 and becoming a member of the State Bar of South Dakota, our community allowed Sr. Erin to volunteer at East River Legal Services in Sioux Falls, SD, from 2008-2012. “During this time, I worked with victims of domestic violence on family law cases. For me this experience was both very rewarding, but also quite heartbreaking. It was rewarding to help those in most need get out of abusive relationships; yet heartbreaking to see the family dysfunction and effects on the children.”

She eventually returned to Mount Marty College, serving part-time as Compliance Officer. This ministry was short-lived, the conclusion of which provided her the opportunity for time away for healing, spiritual growth, and personal renewal. “I currently minister in the Monastery Business Office and Gift Shop, as I continue to seek God and strive to become the person God wants me to be.”

Loving God, by your grace,
Catholic Sisters throughout the world continue to respond to Your Baptismal invitation
to live lives dedicated to prayer and loving service.
Enkindle in their hearts a renewed desire to be zealous servants of the Gospel
and continuing signs of Your presence in our world.
Preserve and strengthen in them the passion and the vision
to welcome and to serve all Your people without hesitation or pause.
As they strive to live the mission of their respective congregations,
empower them to do so with courageous simplicity,
consecrated celibacy, and committed obedience to Your will.
We ask this in union with Jesus the Christ,
who showed these dedicated women the way to living in union with You.  Amen.
