Chicago Mayor Brandon Johnson has named Dr. Garth Walker, the chief medical officer for Rush Health, as his choice to lead the Chicago Department of Public Health, the mayor’s office confirmed.
Nomination and background
Walker, who was announced by the mayor on Tuesday, currently oversees clinical operations for a network that includes Rush University Medical Center. His medical career began in Chicago, included time in Washington, D.C., and has returned him to his hometown, where he said he is honored to be under consideration for the role.
“I feel honored and privileged to, to be selected, and I'm looking forward to continuing this nomination,” Walker said.
If approved by the city’s legislative body, Walker would replace former CDPH Commissioner Dr. Olusimbo Ige, who a mayoral spokesperson said was asked to resign.
Stated priorities and experience
In an interview following the announcement, Walker discussed how his front-line experience as an emergency physician has shaped his approach to public health. He highlighted the personal and community impacts of gun violence, and cited a high-profile case from 2018 when a friend and colleague, Dr. Tamara O'Neal, was fatally shot outside Mercy Hospital.
He said that episode affected his views on the role of clinical and community supports and that, if confirmed, he would consider ways to expand access to mental-health services, particularly in neighborhoods where clinics have closed.
