Charlie Shields

President and CEO

Charlie Sheilds, President and CEOCharlie Shields serves as president and chief executive officer of University Health. Shields joined the system in 2010 as chief operating officer of University Health Lakewood Medical Center. He assumed his current role in 2014.

Shields brings to the role more than 25 years of healthcare leadership and decades of public service, including 20 years in the Missouri General Assembly, culminating his service with two years as president pro-tem of the Missouri Senate.

Shields strongly believes University Health exists for two reasons: 1) To serve as Kansas City's essential hospital, providing quality care to those with the very best insurance and those with no insurance at all. 2) To serve as an academic medical center, preparing the doctors, nurses, dentists and pharmacists of the future, and taking on the toughest cases.

With those two missions in mind when making all decisions, including the best path for the growth of University Health, Shields often has said, "Healthcare doesn't always have to happen within the four walls of a hospital."

During Shields' tenure, much of the system's clinical growth has occurred outside of the University Health Truman Medical Center and University Health Lakewood Medical Center facilities.

University Health 1 changed the look of outpatient care at University Health with a light and bright specialty and surgery center overlooking downtown. University Health Women's Care expanded the organization's ability to serve women in eastern Jackson County. University Health opened University Health On the Go! clinics in area Hy-Vees. Now, that growth continues with University Health 2 making primary and women's care more accessible downtown.

Within those four walls, Shields has worked to make sure University Health patients are seen in areas that reflect the extraordinary care they receive. More private rooms are being added, The Birthplace is receiving a long overdue update, and the Neonatal Intensive Care Unit is more than doubling in size.

During his tenure at University Health Lakewood Medical Center, Shields oversaw significant change and growth, including opening the University Health Women's Care Lakewood Family Birthplace.

Shields shared his expertise when he served as president of the Missouri Hospital Association. He is often quoted saying, "Education is the number-one determinant of economic status, and economic status is the number-one determinant of health status," bringing together the importance of education in living a long and healthy life. With this as a foundational belief, he serves as president of the Missouri State Board of Education. He is also deeply involved in and proud to serve the Kansas City community, holding leadership positions with the Greater Kansas City Chamber of Commerce, the Kansas City Civic Council and the Urban Neighborhood Initiative.

Finally, Shields is a founding board member of the UMKC Health Sciences District, a collaboration between University Health; UMKC schools of Medicine, Pharmacy, Nursing and Dentistry; Children's Mercy Hospital; the Kansas City Health Department; and other entities, creating a true academic health center investing in research, advancing intellectual collaboration and developing a space for health innovation unlike any other in the region.
