Dr. Penny Wheeler announced plans Thursday to retire at year's end as chief executive of Allina Health System, ending her seven-year tenure running one of the state's largest networks of hospitals and clinics.
Lisa Shannon will become the new Allina CEO, having served as the nonprofit group's chief operating officer since 2017. Shannon added the title of president in 2020. Wheeler will remain on the nonprofit group's board of directors.
Wheeler's term has been marked not only by a global pandemic and the racial reckoning following the murder of George Floyd — who was killed just blocks from Allina's headquarters — but also the deep pain of personal tragedies for herself and her employees.
In January, Wheeler's 21-year-old daughter died in Iowa, an accidental death that authorities attributed to excessive drinking and exposure to the cold. A little more than two weeks later, a gunman was arrested after opening fire at an Allina clinic in Buffalo, Minn., killing one person and wounding four others.
In an interview Thursday, Wheeler said she told board leaders about 21⁄2 years ago that she hoped to retire in a couple of years. The experiences over the past 18 months didn't change the timeline, she said, but deepened the experience of running Allina, including going to visit relatives of those injured in the clinic shooting.
"The daughter of one [victim] was an employee of ours, and she draped herself over me and said: 'I'm so sorry about your daughter,' and I said: 'I'm so sorry about your Mom,' " Wheeler recalled. "It was just like this grief, layered on grief, layered on pandemic. I'll never forget that moment."
With more than 28,000 employees, Allina operates more than 90 clinics and 11 hospitals, including Abbott Northwestern in Minneapolis and United in St. Paul.
A dietician by training, Shannon, 56, said her early clinical work impressed on her the value of inter-disciplinary teams in health care. She worked alongside physicians and other caregivers to tackle questions such as how nutrition can help burn patients recover.
