Mary Barra and David Cordani are two well-known business leaders who have spent much of their professional lives leading large organizations through major changes. Although they work in very different industries, their careers share an interesting theme: both have focused on adapting established companies to changing customer needs, technology, and business conditions.
Mary Barra is the Chair and Chief Executive Officer of General Motors (GM), one of the world’s best-known automobile companies. She has been GM’s CEO since 2014 and became chair of the company’s board in 2016. David Cordani, meanwhile, spent many years leading The Cigna Group, a major global health services company. Mary Barra and David Cordani He became Cigna’s CEO in 2009 and moved from the CEO position to Executive Chair in July 2026.
Their industries are different, but looking at their careers together provides an interesting picture of modern corporate leadership.
Who Is Mary Barra?
Mary T. Barra has spent almost her entire professional career at General Motors. Her connection with the company started much earlier than her time as CEO. She began working with GM in 1980 as a co-op student at the Pontiac Motor Division while studying electrical engineering.
Barra later earned a bachelor’s degree in electrical engineering from General Motors Institute, now known as Kettering University. She also earned an MBA from Stanford Graduate School of Business.
Before becoming CEO, Barra held several important positions at GM. Her experience included global product development, purchasing, supply chain, manufacturing engineering, and human resources.
That wide range of experience gave her an unusual understanding of the company. Instead of coming into GM from another industry, she had spent decades learning how different parts of the automobile business worked.
In January 2014, Barra became CEO of General Motors. She became the first woman to lead a major global automaker. GM later elected her chair of the board in 2016.
Today, her leadership at GM includes areas such as electric vehicles, software, advanced technology, and autonomous driving. GM’s leadership page continues to list Barra as Chair and CEO.
Who Is David Cordani?
David Cordani followed a different career path. His professional life has been closely connected with the health services industry and The Cigna Group.
Cordani joined Cigna in 1991 and held several senior positions during his career. His previous roles included Chief Operating Officer, President of Cigna Healthcare, and Senior Vice President for customer segments and marketing.
He became CEO of The Cigna Group in 2009. Over the following years, the company changed significantly as it expanded its health services businesses and developed a broader global presence.
According to Cigna’s board biography, Cordani’s tenure helped the company grow into a global health company with more than 185 million customer relationships and approximately 67,700 colleagues worldwide.
Cordani also focused heavily on technology, data, customer engagement, and changes in the health care system. These areas became increasingly important as customers and businesses looked for more accessible and personalized health services.
In March 2026, The Cigna Group announced that Cordani would retire as CEO on July 1, 2026. Brian Evanko, who had been president and chief operating officer, succeeded him as CEO. Cordani then became Executive Chair of the company’s board.
Mary Barra and David Cordani Have Different Industries
One of the most obvious differences between Mary Barra and David Cordani is the industry they lead.
Barra’s career has been centered on automobiles and manufacturing. General Motors operates in a highly competitive global automotive market where vehicle design, manufacturing, software, batteries, safety, and changing consumer preferences all play important roles.
Cordani’s career has been centered on health services. The health care industry involves insurance, pharmacy services, health data, clinical care, customers, employers, and government regulations.
These industries have different challenges, but both require leaders to understand how quickly their environments can change.
For Barra, one major area of change has been the move toward electrification and software-driven vehicles. GM has described its focus as including electrification, software, and personal autonomous driving technology.
For Cordani, major issues included health care affordability, customer experience, digital capabilities, and the changing needs of patients and communities.
Mary Barra’s Long Journey at General Motors
A major part of Barra’s story is the length of her relationship with GM.
She did not simply arrive at the company and immediately become a senior executive. Her career developed over decades. She worked in technical and management positions before eventually reaching the top leadership position.
That background is important because the automotive industry requires knowledge of many connected areas. Product development, manufacturing, purchasing, engineering, supply chains, employees, and customers all influence the final product.
Barra’s engineering education also became part of her professional identity. Her experience in product development helped prepare her for decisions involving the future direction of GM.
In recent years, technology has become an even bigger part of the Automotive industry. Cars are increasingly connected computers on wheels, with software and digital systems playing a major role alongside traditional mechanical engineering.
GM has continued to report major developments under Barra’s leadership. In July 2026, the company released its second-quarter results and raised its full-year 2026 guidance. Barra and CFO Paul Jacobson also hosted the company’s investor conference call.
David Cordani’s Career at Cigna
Cordani’s career also demonstrates the value of long-term experience inside one organization.
He joined Cigna in 1991 and worked in different leadership positions before becoming CEO. This allowed him to understand the company from several perspectives.
His experience covered operations, health care, customers, marketing, and executive leadership. Over time, his role expanded from managing individual areas of the business to helping guide the company’s broader strategy.
During his time as CEO, Cigna went through significant changes. The company expanded its health services capabilities and became more focused on areas beyond the traditional image of an insurance company.
Cigna’s board says the company grew from a traditional insurer serving 46 million customers with $18 billion in annual revenue into a global health company with 180 million customer relationships and $275 billion in annual revenue during Cordani’s tenure. The figures refer to the comparison highlighted by the company when announcing his leadership transition.
Technology and Change
Technology is another area where the careers of Mary Barra and David Cordani can be compared.
For Barra, technology is changing what an automobile can be. Electric powertrains, vehicle software, connectivity, driver assistance systems, and autonomous driving research are changing the traditional automobile business.
GM has specifically highlighted electrification, software, and autonomous driving as important technology areas.
Cordani’s industry has experienced a similar digital shift, although in a completely different way.
Health services increasingly depend on data, analytics, digital tools, pharmacy technology, and personalized customer experiences. Cigna’s board biography notes Cordani’s understanding of the role that data analytics and digital capabilities can play in improving the health care system and outcomes.
This shows how technology can influence businesses that appear completely unrelated.
Leadership Through Major Transitions
Another interesting part of Mary Barra and David Cordani is the way both have led companies during periods of major transition.
Barra has led GM while the automotive industry has been dealing with changes in consumer preferences, electric vehicles, software, supply chains, and new technology.
Cordani led Cigna during a period when health care companies were dealing with increasing demand for services, rising costs, digital transformation, and changing expectations from customers.
In February 2026, Cordani discussed rising health care costs and identified increasing demand for care, including mental health services, and expensive new drugs and treatments as major pressures on the system.
His comments reflected the broader challenges facing health care companies as they try to balance innovation, affordability, and customer needs.
Their Approach to the Next Generation
Both leaders have also spoken about preparing their organizations for the future.
Barra’s work at GM has involved preparing a traditional automaker for a future where electric vehicles, software, and advanced technology have a larger role.
Cordani’s work involved helping transform Cigna into a broader health services organization. His transition to Executive Chair in 2026 also represents a new stage in his career and in the company’s leadership structure.
Cigna described the CEO transition as a planned move intended to continue the company’s direction while bringing Brian Evanko into the top executive role.
Mary Barra and David Cordani Outside Their CEO Roles
Their professional activities have also extended beyond their primary executive positions.
Barra serves on several boards and organizations, including The Walt Disney Company, the Business Roundtable, the Duke University Board of Trustees, and the Detroit Economic Club.
Cordani has also been involved with nonprofit and business organizations. His activities have included work connected with veterans, community health, and international business relations. He also oversees the David and Sherry Cordani Family Foundation.
In June 2026, The Cigna Group Foundation announced a $1.5 million, 10-year commitment through the David M. Cordani Courage in Service Grant to support military and veteran communities.
What Makes Their Careers Interesting?
The story of Mary Barra and David Cordani is not simply about two CEOs.
Their careers show two different ways that executives can rise to the top of large organizations.
Barra spent her career at GM, moving from an engineering co-op position to the company’s highest leadership role. Her story is closely connected to manufacturing, engineering, automobiles, and technological change.
Cordani joined Cigna in the early 1990s and gradually moved through senior leadership positions before becoming CEO. His career is closely connected to health services, customer needs, data, and the changing health care system.
Both careers also demonstrate how large companies need to adapt.
A car company cannot focus only on traditional engines and manufacturing when software and electrification are changing the industry. Similarly, a health services company cannot focus only on traditional insurance models when customers increasingly expect digital tools, easier access, personalized support, and greater transparency.
Conclusion
Mary Barra and David Cordani have built very different careers, but both have spent decades working in complex industries where change is constant. Barra’s journey from a GM co-op student to Chair and CEO reflects a long career in engineering, manufacturing, product development, and corporate leadership.
Cordani’s journey from joining Cigna in 1991 to leading the company for nearly 17 years reflects a similarly long relationship with one organization and the changing health services industry.
Their stories also show how leadership can evolve as industries change. Barra continues to lead GM as the automotive sector moves deeper into electrification, software, and advanced vehicle technology. Cordani has moved into the Executive Chair role after handing the CEO position to Brian Evanko in July 2026.
Looking at Mary Barra and David Cordani together gives readers a useful way to understand two major areas of American business: automobiles and health services. Their careers are different, but both demonstrate the importance of experience, adaptation, technology, and long-term planning in modern corporate leadership.
