Hospital Sisters Health System announces $270 million investment to increase health care access in Green Bay

Hospital Sisters Health System (HSHS) leaders announced today the nonprofit, regional health system will invest $270 million in strategic capital over the next 3 to 5 years to meet the need for greater health care access in Green Bay and surrounding communities.

At a press conference at HSHS St. Mary’s Hospital Medical Center on March 6, 2025, HSHS Wisconsin Market President and CEO Bob Erickson announced plans to expand and remodel its two hospitals in Green Bay, HSHS St. Mary’s Hospital Medical Center and HSHS St. Vincent Hospital.

“This is much more than an investment in our brick and mortar,” said Erickson. “This investment is Hospital Sisters Health System’s response to a need for greater access to health care in Green Bay. With projected population growth, an aging population and a growing number of patients traveling to Green Bay from afar to seek health care, we see a significant need to open more access to patients who want to receive care from us.”

HSHS St. Mary’s Hospital Medical Center, located at 1726 Shawano Avenue and the only hospital on Green Bay’s west side since 1960, will be the site of the largest expansion and transformation.

“There are tremendous benefits to our community in where St. Mary’s is located,” said John Wagner, Chief Operating Officer, HSHS Wisconsin Market. “Not only does St. Mary's provide Green Bay's west side community greater access to care, but its location off I-41 makes it ideal for easy health care access – for those traveling from as far north as the Upper Peninsula of Michigan to as far south as Fond du Lac, in need of specialty care.”

Preliminary design plans for the expansion and transformation of HSHS St. Mary’s Hospital Medical Center shared at the March 6 press conference include a new tower on the existing campus that would allow for more intermediate and intensive care beds. Early design plans also call for additional operating and procedural rooms, wider corridors and spaces that offer more natural light, plus additional parking and entry to make navigating the hospital campus easier.

“We are taking a very mindful approach to the design plans to ensure we are creating a more spacious environment that promotes health and healing to the highest level and enhances the overall experience for all who come through our doors,” said Wagner.

Construction at HSHS St. Mary’s Hospital Medical Center is expected to begin in summer 2025 and be complete in 2028. Plans are in place to ensure the highest quality of patient care continues, and that patient care will not be disrupted during this time.

A media kit, including B-roll, photos and preliminary renderings of the future HSHS St. Mary’s Hospital Medical Center are also available on the site. Remodeling plans for HSHS St. Vincent Hospital, 835 S. Van Buren St., are still being determined and will be announced at a later date.

HSHS St. Vincent Hospital is home to a Level II Trauma Center, Comprehensive Stroke Center, a Women and Infants Center, and Green Bay’s only children’s hospital – HSHS St. Vincent Children’s Hospital.

HSHS St. Vincent and St. Mary’s Hospitals are Green Bay’s longest serving hospitals. HSHS St. Vincent Hospital was founded as Green Bay’s first hospital in 1888, and in 2025, HSHS St. Mary’s Hospital Medical Center celebrates 125 years of service to the Green Bay community.

“In a time when the health care landscape is changing quicker than we can blink, HSHS stands strong and stable,” said Erickson. “We are here for the long haul, and very excited to be investing in the Green Bay community and furthering our commitment to care for you all for many more years to come.”
