Founded In Wisconsin - Gundersen Health System in La Crosse, Wisconsin

Gundersen Lutheran Hospital, La Crosse, WI

In 1891, Norwegian physician Adolf Gundersen arrived in La Crosse, Wisconsin, holding a medical degree from the Royal University of Oslo. Over the subsequent 50 years, he established a practice, hospital, and a family legacy of community-trusted medicine, which developed into a unique health system in the United States. Today, known as Emplify Health, the organization operates seven hospitals and 65 clinics, employing 15,000 individuals across four states. It faces challenges such as consolidating rivals, reimbursement issues, a physician shortage, and the pressures associated with a new brand name. This post examines Gundersen's origins, accomplishments, and strategic objectives for 2025.

The Gundersen Legacy: Pioneering Medical Excellence Across Generations

Adolf Gundersen, born in Norway in 1865, emerged as a distinguished physician following his graduation from the Royal University of Oslo in 1890. In 1891, he relocated to La Crosse, where he joined Christian Christensen's practice. In 1893, he married Helga Sara Isaksetre, and together they had eight children. Gundersen expanded his medical practice into Minnesota and attended to prominent individuals, including former President William Howard Taft in 1912. In 1902, he became the first medical director of Lutheran Hospital, significantly influencing medical care and patient safety. The hospital initiated an innovative preceptorship for medical students in 1927. In recognition of his contributions, Gundersen was knighted in the Royal Norwegian Order of St. Olaf in 1926 and served as a Fellow of the American College of Surgeons and a Regent of the University of Wisconsin.

Adolf and Helga Gundersen established a medical legacy in Wisconsin, with six of their children pursuing careers in medicine. Gunnar Gundersen, an orthopedic surgeon, gained national recognition, while Alf Gundersen specialized in urology. Sigurd Sr. practiced as a surgeon, with his sons Adolf L. and Sigurd Jr. also entering the medical profession. Thorolf Gundersen organized the internal medicine department, making significant cultural contributions.

Dr. Adolf Gundersen advanced surgical techniques and co-founded the La Crosse Medical Science Consortium. Sigurd B. Gundersen Jr. served as president of Gundersen Clinic, and Jerome Gundersen was a pioneer of the LEEP procedure. Gunnar Gundersen's grandson made advancements in nuclear medicine, and his son, Lincoln, specialized in radiology. Erik Gundersen excelled in pediatric and cardiovascular surgery, performing nearly 5,000 open-heart surgeries, while Dr. Sigurd Gundersen III contributed to research in vascular surgery.

The Clinic in Three National Crises: WWI, the Depression, and WWII

The Great War and the 1918 influenza epidemic significantly disrupted American medical education and the physician workforce, affecting institutions like the University of Wisconsin. Both Lutheran Hospital and the Gundersen practice experienced physician shortages due to military enlistment, exacerbated by the Spanish flu, which resulted in 8,459 deaths in Wisconsin. La Crosse County's advanced public health system maintained a lower death rate compared to neighboring areas. Influenced by European clinical traditions, Lutheran Hospital played a pivotal role, with Adolf Gundersen contributing to medical literature on pneumonia, a severe flu complication.

Wisconsin's prompt public health measures mitigated the epidemic's impact, emphasizing preventive medicine and robust infrastructure, lessons embraced by Gundersen. Adolf Gundersen's post-war reputation grew, influencing American medical education by introducing preceptorships at La Crosse Lutheran Hospital in 1927, setting a national standard.

The Great Depression posed challenges to medical practices, including Gundersen's, as patients encountered financial difficulties. Despite these hardships, Gundersen's practice persevered, accepting alternative payments such as poultry. By the 1930s, La Crosse emerged as a medical center, attracting patients from a tri-state area. The construction of the Gundersen Clinic in 1930 integrated clinical and inpatient care, inspired by the Mayo Clinic model, providing economic resilience through a multi-specialty approach. Adolf Gundersen passed away in 1938, leaving a lasting legacy through the Gundersen Clinic.

During World War II, the clinic faced physician shortages as doctors enlisted in the military. In response, the Gundersen Medical Foundation was established in 1944 to attract medical experts and offer fellowships, transitioning from a family-run practice to a formal entity, ensuring the clinic's survival and growth amid wartime challenges. Following Adolf's death, his sons founded the Gundersen Medical Foundation in 1944 to continue his legacy. Gunnar Gundersen, a renowned orthopedic surgeon and AMA president, warned about the influence of corporate medicine in 1959. The Gundersen family, spanning four generations, has been integral to regional medicine, with Dr. Lincoln H. Gundersen being the last to practice at the family-named hospital.

Gundersen Clinic and Lutheran Hospital: 1946 to 1990

Following World War II, American medicine underwent significant transformation through federal legislation, surgical advancements, and increased hospital investments, exemplified by Gundersen Clinic and Lutheran Hospital in La Crosse. Gundersen Clinic's revenue grew from less than $10 million in 1945 to nearly $140 million in 1990, driven by specialization, governance, education, and expansion. Established in 1891 as a single-physician practice, it evolved into a multi-specialty clinic by 1964, with Dr. A. Erik Gundersen as its 49th physician. During the 1950s, Dr. Adolf L. Gundersen and Sigurd B. Gundersen Jr. introduced innovative surgical techniques and restructured the clinic as a corporation in 1964, incorporating non-family staff into its operations.

In the 1960s, Lutheran Hospital showcased emergency preparedness, and Dr. A. Erik Gundersen performed one of Wisconsin's initial coronary bypass surgeries. The enactment of Medicare and Medicaid in 1965 broadened healthcare access, prompting necessary administrative changes. The 1970s emphasized regional outreach to mitigate rural physician shortages, with Dr. Adolf L. Gundersen advancing medical education and establishing Gundersen Lutheran as the University of Wisconsin School of Medicine’s western campus.

From 1979 to 1990, Dr. Sigurd B. Gundersen Jr. led the clinic, addressing challenges such as DRGs and Medicare reforms, expanding the network, and strengthening the academic mission. Despite financial pressures in the 1980s, Gundersen's corporate structure and educational investments ensured stability. The Gundersen Health Plan was established in 1986 to oversee care management. The Respecting Choices program, developed by Bud Hammes, enhanced the completion of advance directives and influenced global healthcare policy. By 1990, Dr. Gundersen retired, concluding the second generation's leadership, though family members remained actively involved. By 1991, the clinic recorded 780,000 patient visits, employed 1,655 staff, and operated 24 branches across Minnesota, Wisconsin, and Iowa. It evolved into a comprehensive regional health system with a strong academic program, culminating in the 1995 merger of Gundersen Clinic and Lutheran Hospital into Gundersen Lutheran Inc.

In the latter part of the 20th century, Gundersen experienced significant growth, culminating in a 1995 merger to establish Gundersen Lutheran, Inc., marking a new era of managed care in La Crosse. Despite organizational changes, it led advancements in medical ethics and end-of-life care through the Respecting Choices program, gaining international acclaim. By 2013, it transitioned to Gundersen Health System, expanding beyond La Crosse into adjacent regions. Notable achievements include the 2014 Legacy Building project and attaining energy independence via the Gundersen Envision program. The institution's commitment to excellence in care has been recognized with numerous awards and high facility ratings. In 2017, efforts to preserve its history resulted in the establishment of the Gundersen Health System Archives. In 2022, a merger with Bellin Health led to the formation of Emplify Health, set to gradually transition while retaining some original names.

The Gundersen System Today

Emplify Health, previously known as Gundersen, is a prominent healthcare provider serving western Wisconsin, southeastern Minnesota, and northeast Iowa. The organization operates 7 hospitals and 65 clinics, committed to delivering comprehensive care to individuals, supported by a workforce of 15,000 members. As the largest employer in the La Crosse area, the system employs nearly 10,000 staff within the Gundersen region, including 434 physicians and 259 physician assistants and nurse practitioners. The entire Emplify system employs over 15,000 individuals.

Gundersen Lutheran Medical Center, a 325-bed teaching hospital, is acclaimed for its excellence, earning a five-star rating from the Centers for Medicare & Medicaid Services. The hospital has experienced significant growth in admissions, births, and outpatient visits since 2013. Six affiliate hospitals, including Gundersen St. Joseph's and Gundersen Tri-County, serve rural communities with critical access designations. The newly constructed facility in Whitehall signifies a substantial investment in healthcare technology for west-central Wisconsin.

The system has been awarded Healthgrades Five Stars excellence awards in multiple specialties and is rated High Performing by U.S. News in several surgical and care areas. Its heart care services are nationally recognized, supported by specialized centers and programs.

Gundersen's La Crosse Hospital has consistently received the Outstanding Patient Experience Award from Healthgrades for 17 years, placing it in the top 15% of U.S. hospitals. The Emplify system serves 35 counties across four states, with the Gundersen region covering a 21-county area. The organization extends its reach through telemedicine and specialist travel programs, providing expertise to rural areas.

Gundersen Health System: The Hambrick Strategy Diamond

Gundersen is a physician-led, not-for-profit integrated delivery system serving over 550,000 individuals in Wisconsin, Iowa, and Minnesota, with a focus on rural areas. It operates a 325-bed teaching hospital and 48 clinics, employs 453 physicians (42% in primary care), and provides coverage for approximately 73,000 members through the Gundersen Lutheran Health Plan. The merger with Bellin extended its reach into Green Bay and Michigan's Upper Peninsula, enhancing services in underserved regions.

Gundersen has expanded through both organic growth and strategic affiliations, notably the 2022 merger with Bellin, marking a shift towards scaling. The Gundersen Medical Foundation supports education, research, and recruitment, thereby enhancing internal capabilities.

Gundersen competes based on quality, consistently ranking in the top five percent of US hospitals for clinical quality. Its physician-led model prioritizes quality without relying on incentive-based pay. The organization’s mission emphasizes community health, with initiatives such as advance care planning and environmental leadership.

Over its 135-year history, Gundersen has evolved through various stages, from achieving clinical excellence to the upcoming launch of Emplify Health in 2024. Its non-profit model focuses on sustainability through reinvestment, integrating primary care with specialty services, owning a health plan, and maintaining low costs. La Crosse boasts the lowest end-of-life healthcare costs in the US, highlighting Gundersen’s commitment to ethical and economical care that respects patient wishes.

Gundersen's Unique Strengths and Challenges in a Competitive Healthcare Landscape

Gundersen's significant strengths are founded on its extensive regional clinic network and a culture emphasizing behavioral accountability. This network, which spans over four states with more than 65 locations, along with the physician compact, creates formidable barriers for new market entrants. The Respecting Choices program, boasting a 96% advance directive prevalence, exemplifies Gundersen's exceptional integration within the community. Its physician-led governance, medical education pipeline, and established brand are difficult to replicate due to their historical foundation.

While temporary advantages such as energy independence and population health data infrastructure provide value, they diminish as competitors advance. Essential resources like integrated EHRs and quality benchmarking are prevalent across health systems.

Gundersen's primary challenge is recruiting talent in rural areas, a situation worsened by healthcare labor shortages and regional competition. Although the medical education pipeline assists in addressing this issue, it remains a structural challenge that the Bellin merger aims to mitigate through enhanced scale and brand strength.

The Strategic Logic of Gundersen/Emplify Health's Flywheel

The flywheel concept, as inspired by Jim Collins, illustrates a self-reinforcing cycle in which each component propels the next, generating momentum that surpasses any individual initiative. For Gundersen/Emplify Health, this strategy capitalizes on strong community trust, a physician compact ensuring accountability, and a comprehensive regional network, establishing a cycle that is difficult for competitors to replicate.

• The System fosters community trust by investing in proactive health initiatives, reducing costs, and retaining patients through programs like community health partnerships and the Street Medicine Program, which enhance patient loyalty and decrease acquisition costs.

  
  

• Gundersen enhances patient access via a unified digital platform developed with Phase2, providing telehealth services, AI-driven scheduling, and a 24-hour nurse line, thereby improving retention across four states.

  
  

• Gundersen prioritizes quality and experience to bolster patient loyalty. Behavioral standards improve patient experiences, while high patient satisfaction scores and CMS ratings serve as effective marketing tools.

  
  

• Gundersen's health plan, managed by Quartz, integrates insurance and care for 73,000 members. The merger with Bellin expands their reach, focusing on Medicare Advantage and value-based contracts to translate outcomes into revenue.

  
  

• As the insured population increases, demand for specialty care also rises, directing patients to high-margin campuses. Investments such as the $51 million in the Whitehall hospital enhance the referral pipeline.

  
  

• Reinvesting in capacity and talent through the Gundersen Medical Foundation and educational programs accelerates growth, reinforcing community trust and momentum.

Leveraging Sustainable Power in Healthcare: Gundersen's Unique Advantages and Challenges

Hamilton Helmer's Seven Powers framework emphasizes the importance of a sustainable power mechanism that provides both benefits and barriers.

• Gundersen's key asset is its cornered resource, deeply rooted in Wisconsin's medical community and history. Unique relationships, supported by the Gundersen Medical Foundation and initiatives like WARM, create a model that competitors find difficult to replicate without causing disruption to their own systems. Gundersen's physician compact and rural clinic network provide significant advantages over for-profit entities such as HCA and Amazon Clinic. The low end-of-life healthcare costs in La Crosse, attributed to the Advance Care Planning program, highlight an efficiency that does not align with for-profit models.

  
  

• Healthcare switching costs, often underestimated, are substantial at Gundersen. Patients with integrated EHRs and care continuity encounter challenges when switching, while employers face difficulties with network integration investments and multi-year contracts. The Emplify Health MyChart portal further increases switching costs by enhancing the patient experience.

  
  

• The merger with Bellin expanded Gundersen's scale, distributing fixed costs across a broader revenue base compared to single-market competitors, although national entities like Mayo Clinic can replicate such scale economies. Gundersen's process power, demonstrated by its Advance Care Planning and physician culture, is deeply embedded in community transformation, posing moderate barriers to competitors.

  
  

• Gundersen's network effects, while present, lack the compounding benefits seen in digital platforms. The health plan's risk pool and referral network improve with scale, and the ACP community norm strengthens with adoption. However, a significant data network effect that enhances clinical intelligence has yet to be realized.

  
  

• The transition to Emplify Health poses a risk to brand power, with local skepticism regarding the new name, but the system's strength lies in its unchanged care, physicians, and community relationships, which form the foundation of its brand.

Navigating Structural Challenges in the Regional Integrated Health System Industry

The regional integrated health system industry presents significant structural challenges, characterized by strong and increasing pressures from labor suppliers and payer buyers, a moderate-to-high and rising competitive rivalry, and two moderate yet intensifying forces from new entrants and substitutes. Maintaining margins necessitates vigilance, and Gundersen's community trust, integrated network, and owned health plan are crucial for its sustainability.

• Labor Supplier Power: Total compensation constitutes 56% of hospital expenses, with registered nurse wages growing 26.6% faster than inflation. Gundersen encounters heightened challenges due to its rural location and the national physician shortage, despite implementing structural solutions such as the WARM program and a recruitment endowment.

  
  

• Payer Buyer Power: Medicare reimbursement trails behind inflation, covering only 83 cents per dollar spent. The aggressive tactics of commercial insurers, coupled with increased AI utilization in claim denials, exacerbate the situation. Gundersen's ownership of Quartz is vital in mitigating this force.

  
  

• Rivalry: The merger between Sanford and Marshfield Clinic has created a formidable competitor, leading to Gundersen's merger with Bellin. The challenge lies in maintaining competitive parity against Sanford-Marshfield's superior purchasing power and scope.

  
  

• New Entrants: The emergence of urgent care clinics and retail giants like Amazon, CVS, and Walgreens in primary care threatens Gundersen's referral pipeline, though it does not impact its hospital or specialty care business.

  
  

• Substitutes: Trends such as hospital-at-home and telehealth present opportunities for Gundersen, which can leverage its integrated model to capture volume shifts rather than lose them.

The strategic approach is clear: defend against payer power, mitigate labor supplier power, address new rivalry through scale and community depth, and preempt threats from substitutes and new entrants by incorporating these formats within its network.

Navigating Growth and Competition: Gundersen's Strategic Imperatives for 2025

Gundersen stands at a pivotal moment in 2025, having doubled its size through the Bellin merger and rebranded as Emplify Health, while facing a formidable competitor in the Sanford-Marshfield merger. With a 130-year legacy of community trust, a physician compact culture, and an integrated delivery infrastructure, Gundersen possesses significant competitive strengths in regional healthcare. However, it must address challenges such as a $10B competitor, a labor market deficit, and a brand transition with potential dilution risks. The strategic focus should be on strengthening community ties rather than competing on scale.

• Health Plan and Geographic Expansion. The Gundersen Health Plan, currently serving 73,000 members, is not fully capitalizing on its potential reach across a four-state area. The strategic goal is to leverage geographic expansion to increase health plan membership, with a particular focus on large employers in Wisconsin and Medicare Advantage in counties with aging populations.

• Brand Transition and Community Trust. The transition to the Emplify Health brand offers operational efficiencies but poses a risk of diminishing the community trust built under the Gundersen name. A five-year managed transition is advised, maintaining sub-brands and monitoring patient trust levels before phasing out legacy signage.

• Competitive Threats and Strategic Responses. Ambulatory surgery centers and retail health providers present structural challenges by targeting high-margin procedures. Gundersen should prioritize the establishment of branded same-day clinics and health programs at employer sites to capture volume within the Emplify network.

• Digital Front Door and Patient Access. Enhancing the Emplify Health MyChart portal is essential for patient retention, necessitating a multi-year initiative to remove access barriers and prevent patients from turning to competitors.

• Community Depth and Long-term Strategy. Gundersen's strength lies in its deep community ties and physician-centric culture, which should be harnessed to retain both patients and employers. Key strategies include publishing outcomes data and strengthening relationships with employers.

  
  

• Workforce and Data Initiatives. Addressing the rural physician shortage requires expanding programs like WARM and providing incentives for rural commitments. Developing a unified population health data platform is crucial for building network economies and maintaining a competitive edge.

Conclusion

The narrative of Gundersen centers on building and safeguarding trust. Established by Adolf Gundersen, who once accepted poultry as payment, the institution expanded through his sons' surgical innovations and his grandsons' governance reforms and care planning. By 2025, Emplify Health will inherit a 130-year legacy, not merely a health system. Strategic analyses emphasize Gundersen's strengths in human relationships, physician culture, and community trust. While scale and digital access are significant, the primary challenge lies in maintaining its deep regional integration, rendering it indispensable. Adolf Gundersen's instinct for this approach remains crucial today, and the task is to preserve it.
