During her 55-year career at Saint Marys Hospital in Rochester, Minnesota, Sister Mary Brigh Cassidy remained a common person with uncommon capabilities. Even though she worked tirelessly as the hospital administrator, caring for patients and leading the hospital through unparalleled growth, she found time at the end of her busy days to write poetry and reflect on spirituality, nature, and a life dedicated to service. Composed between the years of 1928 and 1968, the poems in Gifts of Her Spirit paint a picture of life through the Great Depression, World War II and post-war events.
