Iris began her teaching career in Killdeer, North Dakota, where she served as both a high school principal and English teacher. She later taught in Aneta and Hillsboro, also in North Dakota. During this period, she attended summer sessions at the University of Minnesota’s School of Library Science, earning her degree in 1946. She spent five years as a school librarian in Staples, Minnesota, before moving to Worthington, where she served as an elementary school librarian until her retirement in 1972.
Westman never married and had no children. She once shared that she had an opportunity to marry, but chose not to — a decision she believed left her parents somewhat disappointed. Nevertheless, she was surrounded by generations of nieces and nephews.
Throughout her life, Iris traveled extensively across the United States with family and friends, and also took tours to Mexico, Canada, and Europe. Wherever she lived, she actively participated in community and church life — especially in choir groups.
In 1990, she moved to Grand Forks and took up residence at Parkwood Place. In May 2012, she relocated to Northwood Deaconess in Northwood.
