HSHS St. Mary's Hospital Medical Center

What HSHS St. Mary's Hospital Medical Center does

HSHS St. Mary's Hospital Medical Center is a non-profit, Catholic-affiliated acute care community hospital located at 1726 Shawano Avenue in Green Bay, Wisconsin, operating continuously since 1903 and currently sponsored by the Hospital Sisters of St. Francis as part of the Hospital Sisters Health System (HSHS). The hospital runs a full-service inpatient and outpatient operation organized around specialty centers including the Center for Heart Health (cardiac catheterization, angioplasty, stenting, cardiac rehabilitation), the Bone and Joint Center, the Center for Digestive Health, the Family Birthing Center with the area's only Certified Nurse Midwife program, a Stroke Center, a Chest Pain Center within the Emergency Department, and a 115,000 square foot Regional Cancer Center opened in 2010 offering chemotherapy and radiation therapy. Adjacent facilities include St. Gianna Clinic (Catholic-aligned family medicine and NaProTECHNOLOGY fertility care) and a connected office complex housing 40+ medical providers for outpatient access.

The hospital generates revenue primarily through professional services: patient care reimbursements from insurance, Medicare, and Medicaid for emergency, surgical, diagnostic imaging, laboratory, inpatient, and outpatient services, plus ambulatory surgery and clinic visits through the Prevea Health network. Prevea Health Services, Inc., formed in 1996 as an integrated delivery partnership with HSHS St. Vincent Hospital and affiliated clinics, extends the hospital's reach across Northeastern Wisconsin and the Upper Peninsula of Michigan. The go-to-market model is sales-led and referral-driven: patients access services through the 24/7 emergency department, scheduled inpatient admissions, outpatient clinics, physician referrals, and community health programs including childbirth classes and a free Speakers Bureau. Service pricing is not publicly disclosed; billing accepts cash, credit card, and PayPal.

The hospital competes in the Green Bay regional market alongside other acute care providers, differentiating on its Franciscan ministry and adherence to Catholic Ethical and Religious Directives, its long community tenure (over 120 years), its first-in-region all-private-room facility, and its integrated delivery model through Prevea Health. Strategic positioning has historically emphasized facility expansion (1960 campus relocation, 1981 rebuild, 1988 birthing center, 1989 Libertas adolescent chemical dependency unit, 1992 ambulatory wing, 2010 cancer center) rather than M&A or geographic expansion beyond the regional catchment. The company has 501-1000 employees and operates as a single-campus community hospital with no subsidiaries, funding rounds, or external equity ownership disclosed.

Direct peers

• HSHS St. Vincent Hospital: Sister acute-care hospital within the same Hospital Sisters Health System, co-located in Green Bay. Co-founding member of the Prevea Health integrated delivery system with HSHS St. Mary's — directly comparable Catholic community hospital serving overlapping west-side/east-side Green Bay markets.
• Bellin Health: Independent, non-Catholic health system headquartered in Green Bay with comparable acute-care hospital, employed physician group, and ambulatory footprint. Head-to-head competitor for patients in the same NE Wisconsin/Upper Peninsula catchment served by HSHS St. Mary's.
• Aurora BayCare Medical Center: Joint-venture community hospital between Advocate Aurora Health and BayCare Clinic in Green Bay. Direct competitor offering acute care, heart, orthopedic, and women's services to the same Brown County patient population as HSHS St. Mary's.

Regional players

• ThedaCare: Non-profit regional health system headquartered in Appleton, WI with multiple community hospitals across the Fox Valley. Comparable in mission, scale, and Catholic-adjacent community footprint to HSHS St. Mary's, but operating in adjacent rather than overlapping geographies.
• Ascension NE Wisconsin: Catholic, faith-based regional hospital system (formerly Affinity/Network Health) operating in the Fox Valley and outlying NE Wisconsin. Same faith-based hospital playbook as HSHS St. Mary's with overlapping philosophy but largely non-overlapping geography.
• Marshfield Clinic Health System: Large physician-led regional health system serving central and northern Wisconsin with hospital and clinic assets. Comparable scale of community hospital footprint with deeply rural coverage — relevant model peer for HSHS St. Mary's regional referral base.
• Gundersen Health System: Non-profit, mission-driven regional health system based in La Crosse, WI serving western Wisconsin, northeastern Iowa, and southeastern Minnesota. Comparable size and acute-care/community-hospital model to HSHS St. Mary's, but serving an adjacent western Wisconsin market.

Emerging players

• Prevea Health: Integrated physician-hospital delivery system co-founded by HSHS St. Mary's in 1996. While a strategic partner, Prevea is also the ambulatory arm that competes for outpatient visits against Bellin and Aurora — making it a partial direct peer to the hospital's outpatient complex.

Broad incumbents

• Froedtert Hospital: Academic tertiary medical center in Milwaukee anchoring the Froedtert ThedaCare Health network. Largest health system in Wisconsin — relevant incumbent comparator for specialty referral patterns that HSHS St. Mary's either retains locally or routes to Milwaukee.
• Advocate Aurora Health: Wisconsin's largest integrated health system (now part of Advocate Health) operating across eastern Wisconsin and northern Illinois. Owns Aurora BayCare in Green Bay and competes system-wide — broad incumbent comparator for the regional HSHS system.
