OSHKOSH, Wis. – Froedtert ThedaCare is pleased to announce the grand opening of ThedaCare Medical Center-Oshkosh, expanding convenient access to care for those living in the region. The opening of the new health campus marks the 20th hospital in the Froedtert ThedaCare system. Care teams are prepared to welcome first patients on Monday, January 19, 2026.
“With the opening of ThedaCare Medical Center–Oshkosh, we’re making it easier for patients and families in northeast and central Wisconsin to get the care they need, close to home,” said Lynn Detterman, President of the North Region of Froedtert ThedaCare. “This new campus strengthens the trusted relationships we’ve built in the region and ensures seamless access to specialized services through our connected system of care.”
ThedaCare Medical Center-Oshkosh is located at 250 W. 6th Avenue on the Fox River in downtown Oshkosh, and complements the area’s major redevelopment and revitalization efforts. Nearly 73% of Oshkosh’s residents live east of Interstate 41, while most of the current health care services are located west of I-41, meaning east-side residents are more than 15 minutes away from a hospital or emergency room.
“In emergencies, every minute matters, and ThedaCare Medical Center–Oshkosh is here to provide immediate care when it’s needed most,” said Jenny Nikolai, Vice President of ThedaCare Medical Centers-Fond du Lac and Oshkosh. “If a person requires a higher level of care, we’ll ensure a seamless transition within our integrated system to get them to the right place quickly.” The organization broke ground on the health campus in March 2024.
Enhancing Access to the Community
ThedaCare Medical Center-Oshkosh is designed to provide comprehensive care 24 hours a day, seven days a week, 365 days a year. The health campus is approximately 114,000 sq. ft., with an estimated $84M investment in the Oshkosh community.
Services at ThedaCare Medical Center-Oshkosh will include:
24/7 Emergency Care
Inpatient Care
Outpatient Surgery
Primary Care
Pediatrics
Specialty Care
Drive-thru Retail Pharmacy
Imaging Services: CT, X-Ray, Ultrasound, Mammography, MRI and Nuclear Medicine
Lab Services
To adapt to the changing needs of the community, ThedaCare updated plans for the health campus and added a 28,000-square-foot third floor to the original design. More services may be added over time based on community need.
“This new health campus is about more than just expanding services – it’s about being here for our neighbors,” said Detterman. “We’re proud to continue caring for the Oshkosh community and to deliver the high-quality, expert care they deserve.”
Throughout the project, ThedaCare worked with partners including Miron Construction, HGA and Hplex Solutions. The teams have worked diligently to support the design and construction of the facility.
Recruitment efforts continue for dedicated team members. Approximately 60 new jobs were created for caregivers and staff at the campus. That number is expected to grow over time as more services are added at the facility.
