When Sr. Mary Eileen Wilhelm, RSM, arrived in Daphne, Alabama, in 1966 to be director of nursing at a tiny rest home called Villa Mercy, she described the experience as a bit of a shock.
"Are you kidding?" she told The Baldwin Press Register in Alabama for a story about her retirement in 2003. "I had just come from this huge congregation in Baltimore. I just couldn't have imagined this."
Sr. Wilhelm became administrator of the care home just outside Mobile and under her leadership it transformed into Mercy Medical, a continuum-of-care network that included five residential communities, three assisted living facilities, two independent life care communities, as well as numerous outpatient services, home care, and one of the nation's first hospice programs. Sr. Wilhelm retired in 2003 as Mercy Medical's president and CEO.
Villa Mercy itself grew from a struggling 45-bed facility, that Sr. Wilhelm at one point was advised to close, to a 135-bed one. The expansion required petitioning the state to change its plan for governing skilled nursing beds.
Sr. Mary Fanning, RSM, a former colleague and longtime friend, said that with Sr. Wilhelm in charge, Villa Mercy "expanded its mission beyond traditional elderly care. It became a provider for individuals with the highest medical needs, including quadriplegic patients, individuals with profound cerebral palsy, and eventually ventilator-dependent patients — services that sharply contrasted with the lower-quality, maintenance-focused care common in surrounding for-profit facilities."
Sr. Wilhelm died on March 6, 2026, in Mobile. She was 87. In addition to her visionary leadership of Mercy Medical, she served on the CHA Board of Trustees from 1984 to 1989, including as chair the last two years, and then was an honorary life trustee. In 2004 she was honored with CHA's Lifetime Achievement Award.
A dedicated servant
Sr. Mary Haddad, RSM, president and CEO of CHA, said Sr. Wilhelm dedicated her life to serving those most in need of health care.
"Throughout her career as a staff nurse, hospital administrator, and board member, she was recognized for her compassionate care and unwavering leadership, leaving an indelible mark on Catholic health care," Sr. Mary said.
In 1987, in one of her first duties as CHA board chair, Sr. Wilhelm met with Pope John Paul II during his visit to Phoenix.
"We had known for a year and a half that he was coming," she told The Mobile Press in Alabama, "so I spent a year and a half being nervous about it."
She told Catholic Health World: "It is a memory I will treasure for the rest of my life."
Sr. Wilhelm was born in St. Louis and grew up in Mobile. After graduating from Providence School of Nursing in Mobile, she entered the Sisters of Mercy order. Her identical twin, Sr. Mary Ann Wilhelm, entered the order later that year.
Sr. Wilhelm earned a bachelor's degree in sociology at Mount St. Agnes College in Baltimore and a master's degree in business administration at George Washington University in Washington.
Building up Mercy Medical
When Sr. Fanning joined the Villa Mercy administrative team as director of admissions, Sr. Wilhelm was administrator and her twin was director of nursing. "Mary Eileen was a creative, innovative leader in the delivery of long-term care and chronic care of persons with complex needs," Sr. Fanning said.
With Sr. Wilhelm in charge, Villa Mercy widened its mission beyond elderly care to help those with high medical needs and introduced hospice care in the area, The Baldwin Press Register noted.
Because of a shift to a blended Medicaid reimbursement rate statewide in the early 1980s, Villa Mercy changed its classification to specialty hospital under Medicare. The change brought in enough funding to make its operations sustainable but required what Sr. Fanning called a "heartbreaking" decision to transfer several long-term residents.
Over the years, Mercy Medical expanded but by 2012 it had sold its main campus in Daphne and had buyers for its other facilities.
After Sr. Wilhelm and her twin retired from Mercy Medical, they relocated to Baltimore. In 2019 they returned to Alabama and lived at the Convent of Mercy in Mobile. Sr. Mary Ann Wilhelm died in 2024.
Sr. Mary Eileen Wilhelm's online obituary notes that in her final days, "she called upon hospice, a gift that she and her sister had made available for so many others, to accompany her in her final journey."
A funeral Mass and celebration of Sr. Wilhelm's life will be on March 20 at Holy Family Catholic Church in Mobile with interment to follow at The Catholic Cemetery.
