Mary Barra and David Cordani have built long careers at major companies, but their professional paths developed in very different industries. Barra rose through General Motors and became the company’s Chair and CEO.

Mary Barra’s Early Career at General Motors
Mary Barra’s connection with General Motors began long before she became the company’s CEO.
She started her career at GM in 1980 as a co-op student at the Pontiac Motor Division. That early experience introduced her to the company from an operational and technical perspective.
Barra later earned a bachelor’s degree in electrical engineering from General Motors Institute, now Kettering University. She followed that with an MBA from Stanford Graduate School of Business.
Her career at GM developed over several decades. Instead of moving directly into senior management, she worked across different parts of the organization and gradually took on greater responsibility.
Moving Through Different GM Roles
Before becoming CEO, Barra held several senior positions at General Motors.
Her background included global product development, purchasing and supply chain, human resources, and manufacturing engineering. She also served as an executive vice president before becoming CEO.
This broad experience gave her exposure to different parts of the automotive business. It also meant that she had worked with both technical and business-focused responsibilities before reaching GM’s top leadership position.
Barra became CEO of General Motors in January 2014. In 2016, she became Chair of the company’s Board of Directors. She continues to hold both positions in 2026.
Mary Barra and the Changing Auto Industry
The automotive industry has changed significantly during Barra’s time as CEO.
Electric vehicles, software, connected technologies, and advanced driving systems have become increasingly important areas for automakers. GM’s official profile describes Barra’s focus on areas including electrification, software, and personal autonomous driving.
Her long career inside GM is relevant to this changing environment because she has experience in several areas of the company’s operations.
Rather than coming from only one business function, Barra has worked in engineering, manufacturing, product development, purchasing, supply chain, and human resources. That background gives her a broad view of how a large automotive company operates.
GM’s 2026 updates also continue to identify Barra as Chair and CEO while the company works across its vehicle, software, and technology businesses.
David Cordani’s Career in Healthcare
David Cordani followed a different route.
His professional career developed in healthcare, where he eventually became one of the most senior executives at Cigna.
Cordani became CEO in 2009 and remained in that position until July 1, 2026. The Cigna Group describes his tenure as nearly 17 years. During that period, the company expanded its business and developed a broader health-services model.
Cordani’s educational background also has a business focus. Texas A&M University says he earned his bachelor’s degree in accounting from Mays Business School in 1988.
Building a Broader Healthcare Business
A major development during Cordani’s time as CEO was Cigna’s acquisition of Express Scripts in 2018.
The transaction helped create the foundation for Evernorth, the company’s health-services business. This expansion became an important part of Cigna’s move toward a broader healthcare model rather than focusing only on traditional insurance activities.
According to The Cigna Group, the organization changed substantially during Cordani’s tenure, expanding its portfolio and developing additional health-services capabilities.
This period made Cordani’s role more than a matter of overseeing an established insurance company. He was also involved in a significant change in the company’s overall business structure.
David Cordani’s Leadership Transition in 2026
There is an important update to keep in mind when discussing David Cordani today.
Cordani is no longer the CEO of The Cigna Group. The company announced in March 2026 that he would retire as CEO effective July 1, 2026, and become Executive Chair of the Board of Directors. Brian Evanko succeeded him as CEO.
The company also said Cordani and Evanko would work closely during the transition period leading up to July 1.
This means older articles that simply describe Cordani as Cigna’s current CEO are now outdated. For content published after July 1, 2026, his Executive Chair role should be used when describing his current position.
What Mary Barra and David Cordani Have in Common
Their industries are different, but their career journeys have several similarities.
Both Developed Long Careers
Neither executive reached the top of a major company through a single career move.
Barra joined GM in 1980 and worked across several areas before becoming CEO. Cordani spent many years building his career in healthcare before becoming Cigna’s CEO in 2009.
Their careers show how experience can accumulate over time as executives move through different responsibilities.
Both Gained Experience Across Business Functions
Barra’s GM career included engineering, manufacturing, human resources, product development, purchasing, and supply chain.
Cordani’s career developed within the healthcare industry and eventually involved responsibility for a much broader organization as Cigna expanded its health-services operations.
This type of varied experience can give senior executives a wider understanding of how different parts of a company work together.
Both Led Through Industry Change
Barra has led GM during a period of major technological change in the automotive industry.
Cordani led Cigna during significant changes in healthcare services and the company’s business structure.
The industries are not the same, but both leadership journeys involved managing large organizations while their business environments continued to evolve.
How Their Careers Differ
The differences between Barra and Cordani are just as important as their similarities.
Different Industries
Barra’s career is rooted in automotive engineering, manufacturing, product development, and technology.
Cordani’s career is rooted in healthcare, insurance, and health services.
Because of this, the challenges they faced as executives were shaped by very different markets and customers.
Different Educational Backgrounds
Barra studied electrical engineering before earning her MBA. Her education reflects both a technical foundation and later business training.
Cordani earned his bachelor’s degree in accounting from Texas A&M University and later completed an MBA.
Their academic paths were different, but both combined formal education with many years of practical business experience.
Different Leadership Positions in 2026
Their current roles are also different.
Barra remains Chair and CEO of General Motors.
Cordani moved from CEO to Executive Chair of The Cigna Group on July 1, 2026. Brian Evanko took over as CEO.
That makes 2026 an important point in both career timelines, but for different reasons.
What Their Careers Reveal About Corporate Leadership
The professional journeys of Mary Barra and David Cordani show that there is no single route to senior corporate leadership.
One clear theme is the value of broad experience. Barra worked across multiple functions at GM before becoming CEO. Cordani also developed his career over many years before reaching the top position at Cigna.
Another theme is adaptability.
Large organizations operate in changing environments. Automotive companies are dealing with new technologies and changing mobility expectations, while healthcare companies continue to adjust to new services, technology, and customer needs.
For executives, that means understanding not only how a company operates today but also how its industry is changing.

Their current positions provide two different examples of executive leadership: one continuing in the combined Chair and CEO role, and the other moving from CEO into an Executive Chair position.
