GREEN BAY, Wis. — HSHS St. Mary’s Hospital Medical Center is one step closer to a new six-story, state-of-the-art inpatient tower that will increase access to care on Green Bay’s west side. Demolition is now underway on the hospital’s North Building— the future site of the new tower— marking the latest milestone in HSHS’ historic $270 million capital investment to revitalize its Green Bay hospitals.
The North Building is separate from the main hospital building and has been a part of the St. Mary’s campus since 1958. In recent years, it was used for a range of clinic and administrative needs.
The new patient tower will significantly expand the hospital’s capacity to care for the community, with more than 100 new patient rooms for medical/surgical and intensive care. Most notably, capacity for intensive care patients at St. Mary’s will more than quadruple, growing from eight beds to 36. The tower will also include two new cardiovascular operating rooms and a cardiac procedural room.
“We recognize the history held within these walls, and now our mission requires us to look forward at the needs of our community,” said Bob Erickson, President and CEO, HSHS Wisconsin Market. “We already see a demand for higher acuity care at St. Mary’s— for those navigating illnesses, surgical procedures or requiring intensive care— which will only continue as our population grows and ages. Adding this tower will ensure more patients have access to the care they need in a more modern environment that matches our clinical excellence.”
For the past several months, contractors have been dismantling the inside of the North Building piece by piece, taking a “surgical” approach to prepare the structure for demolition. Every step of the demolition and subsequent construction has been meticulously designed to ensure patient care is not interrupted and all services in the main hospital remain fully operational.
Work is also being done to revitalize the larger hospital campus, including the creation of a new main entrance, added parking and enhanced security features. New kitchen and dining are also part of the remodeling plans.
“While we work to transform our physical space, our commitment to providing exceptional care remains strong,” said Leah Bergstrom, Chief Administrative Officer at HSHS St. Mary’s Hospital Medical Center. “Our main priority will always be to deliver the highest standard of care in the present, while we build new infrastructure to enhance it for the future.”
In alignment with the mission of The Hospital Sisters of St. Francis, the order of Franciscan Sisters who founded HSHS, the ongoing demolition and expansion at St. Mary’s is being executed with a focus on environmental sustainability and community mindfulness.
When a different building on the campus was demolished in fall 2025 as part of the expansion project, HSHS utilized an innovative onsite recycling process. Rather than transporting waste to landfills, recyclable items were separated and concrete materials were crushed to be reused as foundational fill for the hospital’s new patient tower.
As work transitions to demolition of the North Building, HSHS remains committed to repurposing and recycling construction materials. Beyond structural recycling, medical equipment and furnishings from the now-vacant North Building have been donated to organizations like Hospital Sisters Mission Outreach— which distributes medical supplies to communities in need around the world— and the Greater Green Bay Habitat for Humanity— which supports local housing initiatives.
“By keeping these materials out of landfills and placing them back into the service of others, we are honoring our founding Sisters’ commitment to stewardship and the care of our environment,” said Erickson.
Groundbreaking on the new patient tower is expected to take place in late summer/early fall this year. The entire St. Mary’s revitalization project is anticipated for completion in 2028. For more information about the St. Mary’s project, please visit: www.stmarysgb.org/future
