Ministry has taken Sister Mary Catherine Fodrocy to several places in Michigan. She has served in Grand Rapids, Saginaw, Ravenna, Ionia, Remus, Three Rivers, and Kalamazoo.  She recently retired from St. Joseph Parish, Kalamazoo, after 24 years as pastoral associate there.

Various ministry roles throughout Sr. Mary Catherine's life have been teaching, administration, and pastoral ministry with people from 6 to 100 years old. She has been involved in sacramental preparation for adults, primarily through the Rite of Christian Initiation of Adults (RCIA) since the beginning of its implementation in the United States after Vatican II. The unifying thread through these ministries has been walking with people through the ups and downs, twists and turns of our journey of faith together.
