New renderings unveiled of the future HSHS St. Mary’s Hospital Medical Center campus

Prep work to begin this month on hospital transformation project

GREEN BAY, Wis. — HSHS St. Mary’s Hospital Medical Center is pleased to share updated architectural renderings for its upcoming campus transformation, offering the community a refreshed look at the future of patient care as early construction activity begins on campus this month. 

As first announced in March 2025, Hospital Sisters Health System (HSHS) is investing a historic $270 million in strategic capital over the next 3 to 5 years to meet the need for greater health care access in Green Bay. It will remodel its two Green Bay hospitals, HSHS St. Vincent Hospital and HSHS St. Mary’s Hospital Medical Center, which will be the site of the largest expansion and transformation. This includes the addition of a new tower that will allow St. Mary’s to add more beds and provide more inpatient care.  

While the overall vision of the future St. Mary’s campus remains consistent with the initial renderings shared in March 2025, these new images incorporate design refinements as the hospital moves through the planning and pre-construction phase of its major transformation project. 

“As we prepare our St. Mary’s campus for the exciting changes ahead, we want our community to see how the vision is evolving,” said Leah Bergstrom, Chief Administrative Officer at HSHS St. Mary’s Hospital Medical Center. “These updated renderings represent the thoughtful progress our team has made to ensure every detail supports the best possible experience for all who come through our doors.”  

Plans for St. Mary’s include: 

• A new patient tower to include added intermediate and intensive care beds. The tower will replace an existing structure on campus built in 1958. The vision is to design the tower for additional growth in the future, should community need arise.  
• More operation and procedural rooms. 
• More natural light within the hospital, creating a welcoming and healing environment for all. 
• The use of brick, metal panel and glass throughout the exterior design to complement the existing campus architecture. More landscaping will also be added to beautify the campus and surrounding neighborhood. 
• Improved parking access and clearer wayfinding to create a smoother arrival experience, helping reduce stress for patients, visitors and staff. 
• Safety is a top priority, with improved visibility, upgraded lighting and secure access points. 

“This is more than just a renovation, it’s an investment in the future of our community’s health,” said Bergstrom.

Early construction activity will begin on the St. Mary’s campus this month to prepare the site for the larger renovation effort. This preliminary work includes site preparation to support a seamless transition into the main construction phase. Opportunity for media interviews and video/photos of site preparation work will be made available next week, with more details coming soon. 

Groundbreaking on the new patient tower at St. Mary’s is anticipated for Summer 2026, with full project completion by 2028. Plans are still in progress for renovations at St. Vincent Hospital and will be shared when more information becomes available.
