Children’s Mercy Hospital Kansas Expansion Plan
The future of CMHK is Built for Kids™
Growing together
In April 2025, Children’s Mercy Kansas City announced a $152 million expansion plan for Children’s Mercy Kansas in Overland Park, Kan. The four-year project will enhance patient care, introduce new clinical programs and give more families access to world-class care — closer to home.
- More surgical capacity.
- All outpatient services gathered in one new medical office building.
- New programs, including Inpatient Rehabilitation, intensive outpatient programs, an expanded Pediatric Motility program and a Neuroscience Center of Excellence.
- And more!
Here when they need us
When it comes to kids, you need quick, close and quality. Our expanded services in Overland Park already serves thousands, and now, there's room for more.
Know before you go
The Tom Watson Emergency Center, 5805 W. 110th Street, is open and will stay open through the entire project.
We will continue to care for kids and families in our community during construction.
