Sister Ann McGuinn Dies at the Age of 85


Napa, CA – Sister Ann McGuinn, former Administrator at Queen of the Valley Hospital was remembered at a memorial mass held Wednesday at St. Apollinaris Catholic Church. More than 150 people attended the celebration to offer their respects and to reflect on a life dedicated to healing.  Sister Ann McGuinn was remembered as a woman of incredible strength, courage and leadership. She was 85 years old.

In 1971, Sister Ann assumed the leadership of Queen of the Valley, serving the Napa community for two decades. During those 20 years, her vision and determination helped prepare the Queen to transition from a small community hospital to the medical center it is today, with state-of-the-art technology and services. She also continued to work to extend the healing ministry beyond the walls of the hospital, reaching out to farm workers, children, and the elderly. The Sister Ann Dental Clinic, which serves the needs of children without access to care, remains to this day as a symbol of the many ways Sister Ann touched the Napa community.

"Sister Ann was a person of compassion, strong character, and commitment in her leadership at Queen of the Valley Hospital and in providing support to the vulnerable in Napa County," said Dennis Sisto, President & CEO of Queen of the Valley. "I will always treasure her wisdom, guidance, and vision in the way she positioned the Hospital to ensure its long-term success.  Everyone that worked with Sister Ann loved her dearly and will always remember her as the true ‘Queen’ of our Valley."

Sister Ann arrived at the Queen with a simple goal—to update the services already provided and to establish new services for the community.  In just eight years under her leadership, and just in time for the hospital’s 20th anniversary, she had already accomplished the building of a new west wing; the addition of several new services including kidney dialysis and mammography; the installation of cardiac monitors, a linear accelerator, and the Valley’s first CT scanner.  She also established the areas first neonatal intensive care unit and helped to create Queen of the Valley’s Regional Cancer Center.

"Sister Ann’s extraordinarily compassionate presence touched countless lives throughout the communities she served. Even as we deeply grieve her loss, we celebrate her remarkable life – a life dedicated to God, and to serving the poorest and most vulnerable in His name," said Sister Marian Schubert, Vice President of Mission Integration for Queen of the Valley Medical Center.

 Sister Ann entered religious life at the age of 22, choosing to join the congregation she had come to know and love as her grade school teachers: the Sisters of St. Joseph of Orange. Trained as an OB nurse, Sister Ann began working at St. Joseph Hospital in Orange in 1946, where her leadership skills and talents were quickly noticed. In 1953, she was given the assignment of Superior and Administrator of St. Joseph Hospital in Eureka.

Sister Ann McGuinn embodied the noblest aspirations that we strive to achieve. She worked to insure that our hospitals deliver the highest quality of care for all, and that they extend their touch into the communities to those who are unable to afford that care.  She had a vision for a just and caring world where every member of the community is attuned to the needs of one another and acts to provide what is best for the common good. Most of all, as a Sister of St. Joseph of Orange, she dedicated her life to service: to serving people, to serving the community, and to serving God. Her presence in our lives was a gift this community can treasure forever.
