GREEN BAY, WI (WTAQ-WLUK) — A Green Bay hospital is getting closer to starting a major expansion project.
HSHS St. Mary’s Hospital Medical Center on Shawano Avenue shared updated architectural renderings for its upcoming campus transformation Thursday.
First announced in March 2025, HSHS is investing a historic $270 million over the next three to five years to remodel its two Green Bay hospitals, HSHS St. Vincent Hospital and HSHS St. Mary’s Hospital Medical Center.
St. Mary’s 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.
“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.
Early construction activity will begin on the St. Mary’s campus this month to prepare the site for the larger renovation effort.
Groundbreaking on the new patient tower at St. Mary’s is expected 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.
