Sister Monica Heeran

Sister Monica Heeran died peacefully on the morning of 9 October 2026 at St. Mary-on-the-Lake in Bellevue, Washington. She was 95. Her obituary was published by Columbia Funeral Home and Crematory on 14 October, and PeaceHealth announced her death on 16 October. No cause of death was made public.

PeaceHealth president and chief executive Sarah Ness said she had been a transformational leader driven by God's will to help those who needed it most, and that she had continued to guide the system until her final days. Public radio station KLCC in Eugene reported her death, and her obituary also appeared in the Eugene Register-Guard.

A vigil service was set for 4 p.m. on Sunday 18 October 2026 and a Mass of Christian Burial for Monday 19 October, both at St. Mary-on-the-Lake and both streamed online. Burial was planned for Tuesday 20 October 2026 at Holyrood Catholic Cemetery. The family asked for donations to the Sisters of St. Joseph of Peace Retirement Fund in lieu of flowers, and PeaceHealth invited gifts in her memory to its Leadership in Ministry Endowment.

Monica Heeran was born on 14 September 1931 in Fenagh, County Leitrim, Ireland, one of the many children of James Heeran and Anne Heeran, née O'Rourke. At the age of seven she was stricken with osteomyelitis, a bone infection. She spent three years in and out of hospitals and was confined to bed for eleven months, and she later said the experience planted the seeds of her desire to become a nurse.

As a teenager she chose to join the Sisters of St. Joseph of Peace, a congregation founded in England in 1884 that ran hospitals in the American Northwest. Her congregation's obituary dates her entry to 1947, and PeaceHealth says she came to the United States in 1948 at the age of 15. She knew the decision would take her far from her home and family. She travelled from Ireland to Bellingham, Washington, for her novitiate, received the religious name Sister Gertrude, and professed her final vows on 15 August 1953. Her younger sister, Anita, also became a Sister of St. Joseph of Peace.

Sister Monica began her long ministry in health care as a receptionist and bookkeeper at St. Anthony's Hospital in Wenatchee, Washington. Her dream of nursing came true in 1961, when she qualified as a registered nurse at Sacred Heart in Eugene, Oregon. She went on to earn a bachelor's degree in nursing from Seattle University in 1963 and a master's degree in hospital administration from Saint Louis University (PeaceHealth gives the year as 1968, her obituary as 1970).

From 1968 to 1973 she was an administrator at hospitals run by her congregation in Bellingham, Washington, and Ketchikan, Alaska. In 1973 she became administrator of Sacred Heart Medical Center in Eugene, a post she held until 1988, and she helped transform it into a multispecialty regional medical center. During those years she established the Sacred Heart Prenatal Clinic for low-income pregnant women, played a leading role in founding the Lane County Psychiatric Hospital and championed the development of Peace Harbor Hospital in Florence, Oregon.

In 1988 she became the second president and chief executive officer of PeaceHealth, the health system the sisters had begun in 1890, and she held the post until 1997. She encouraged doctors and community leaders to take part in running the hospitals, seeing health care as a ministry to the whole community. In 1994 she guided PeaceHealth's transition to become the first Pontifical Private Juridic Person, a canonical structure that allowed it to remain officially Catholic while being led by lay people rather than by a religious order. In the 1990s she was also at the forefront of Oregon's Medicaid reform, leading a workgroup that helped the state achieve one of the highest health coverage rates in the nation.

After her retirement in 1999 she took up an idea brought to Eugene that year: a free clinic staffed by retired and volunteer medical professionals, modelled on the first Volunteers in Medicine clinic in South Carolina. With a founding board of eleven people she studied the needs of the uninsured in Lane County, raised money and recruited volunteers. The Volunteers in Medicine Clinic of Lane County opened in West Eugene on 1 February 2001 with Sister Monica as its volunteer executive director. She later chaired its board and stepped down from the board in 2011, staying on as an emeritus adviser.

As a vowed member of the Sisters of St. Joseph of Peace, Sister Monica did not marry. She lived her later years at St. Mary-on-the-Lake in Bellevue, Washington, the congregation's home in the Western region, and in June 2023 she marked 75 years of religious life at a jubilee there. Looking back at her 50th jubilee, she said she had been accompanied by dedicated women and men who dared to make a difference in serving the sick, and that the goodness she saw around her gave her great hope for the future.

Sister Monica's work runs through the modern shape of Catholic health care in the Northwest. Sacred Heart in Eugene grew into a regional medical center under her, and the clinics and hospitals she helped found served groups that had been left out, from low-income mothers to psychiatric patients and the rural coast. Her steering of PeaceHealth into a lay-led Catholic structure in 1994 was the first of its kind, and it allowed the system to remain Catholic as lay leaders took over from the sisters.

The Volunteers in Medicine Clinic she founded in retirement passed its 100,000th patient visit within ten years and, by its twentieth anniversary, had served more than 18,000 people with a corps of up to 350 volunteers. The Catholic Health Association's 2008 Lifetime Achievement Award described her as proof that one committed individual can change the world.
