Tina Garrison has stepped down from her role as regional COO for St. Louis-based SSM Health.
She reached her 25-year anniversary with SSM Health earlier in 2026 and wrapped up her time with the organization in September, she wrote in a Sept. 18 LinkedIn post.
Ms. Garrison served as COO of the St. Louis and Southern Illinois regions from March 2023 until September, according to her LinkedIn profile. Before that, she was president of DePaul Hospital in Bridgeton, Mo.
She first joined SSM Health in 2001 as director of quality appraisal services at St. Mary’s and Good Samaritan Hospitals in Mount Vernon, Ill.
Ms. Garrison described her time with the system as a privilege.
“I have had opportunities I never could have imagined when I first began, worked alongside some truly extraordinary people, learned more than I can possibly capture here, and had the chance to do meaningful work in service to our patients and communities,” she wrote in the post.
