When people search for Doug McMillon and Joaquin Duato, they are often looking at two executives who have reached the top of very different industries. McMillon built a decades-long career at Walmart, while Duato spent almost four decades at Johnson & Johnson. Their paths rarely overlap directly, but their careers offer an interesting comparison of global leadership, technology, innovation, and long-term corporate transformation.
What Is the Connection Between Doug McMillon and Joaquin Duato?
There is no widely documented personal or professional partnership between Doug McMillon and Joaquin Duato. Instead, the two names appear together because both have been influential leaders of major multinational companies.
McMillon led Walmart as president and CEO from February 2014 through January 2026. He began his Walmart career as an hourly associate in 1984 and eventually moved through senior leadership positions before becoming the company’s top executive.
Duato, meanwhile, became Johnson & Johnson’s CEO in January 2022 and chairman in January 2023. He joined Johnson & Johnson in 1989 and developed a career spanning pharmaceuticals, medical technology, international operations, technology, and supply chain leadership.
The strongest reason for comparing them is therefore not a shared company or known partnership, but their positions as leaders of enormous global organizations.
The Story Behind Doug McMillon’s Career
From Walmart Associate to CEO
Doug McMillon’s career has an unusual feature: he rose through the same company he eventually led.
According to Walmart, McMillon started as an hourly associate at age 17. His career subsequently included leadership positions in Sam’s Club and Walmart International before he became Walmart’s president and CEO in 2014.
His progression gave him experience in several areas of retail rather than just one corporate function.
Before becoming CEO, McMillon served as:
- President and CEO of Sam’s Club
- Executive vice president and president and CEO of Walmart International
- Senior Walmart leader involved in international operations
- President and CEO of Walmart beginning in 2014
His educational background includes a bachelor’s degree in accounting from the University of Arkansas and an MBA from the University of Tulsa.
McMillon’s Walmart Era
McMillon’s tenure coincided with a major transformation in retail.
Walmart invested heavily in e-commerce, technology, supply-chain capabilities and omnichannel shopping. The company’s own retrospective describes the period as a shift toward a people-led, technology-powered retailer.
One notable moment came in 2015, when Walmart announced a $2.7 billion investment over two years in its U.S. workforce, including higher wages and education and training opportunities.
McMillon retired as Walmart’s CEO on January 31, 2026, with John Furner succeeding him as president and CEO.
That makes his current role an important distinction: he should not be described as Walmart’s current CEO in a 2026 article.
Joaquin Duato’s Rise at Johnson & Johnson
A Career Built Inside Healthcare
Joaquin Duato followed a similarly long internal career, but in healthcare rather than retail.
He joined Johnson & Johnson in 1989 with Janssen in Spain. Over the following decades, he held positions across countries, business segments and corporate functions. His experience eventually included senior responsibility for the company’s pharmaceutical business.
Duato became CEO in January 2022 and chairman one year later. Johnson & Johnson describes his leadership focus around innovative medicines and MedTech, with particular attention to oncology, immunology, neuroscience, cardiovascular care, surgery and vision.
His international background is also notable. Duato is a dual citizen of the United States and Spain and holds an MBA from ESADE in Barcelona and a Master of International Management from Thunderbird School of Global Management.
Technology and Healthcare Innovation
Duato’s leadership comes at a time when healthcare is becoming increasingly connected with artificial intelligence, data science and advanced medical technologies.
Johnson & Johnson says Duato views AI as a force multiplier and has emphasized combining technology with professional expertise. The company’s current strategy focuses on areas where scientific research and technological development can address significant unmet medical needs.
This differs from McMillon’s technology challenge. Walmart’s transformation centered heavily on digital commerce, inventory, logistics, automation and customer experience, whereas Johnson & Johnson operates within scientific, medical and regulatory environments.

Why Are Doug McMillon and Joaquin Duato Often Discussed Together?
The search interest surrounding Doug McMillon and Joaquin Duato appears to reflect broader curiosity about influential corporate leaders rather than evidence of a direct partnership.
Both executives have participated in wider business leadership circles. Duato is currently listed by Business Roundtable as a member, while historical records show McMillon serving in Business Roundtable leadership and as its chairman from January 2020 through December 2021.
Duato was also among executives who participated in discussions surrounding the 2019 Business Roundtable Statement on the Purpose of a Corporation. McMillon publicly discussed long-term business value and stakeholder considerations during the same broader period.
This provides some institutional context for why the careers of major CEOs can sometimes be discussed within the same business-leadership conversations.
Two Different Models of Corporate Transformation
The most interesting comparison between McMillon and Duato may be the environments in which they operate.
McMillon and the Retail Revolution
McMillon’s Walmart leadership unfolded during the rapid expansion of online shopping.
Consumers increasingly expected retailers to connect physical stores, websites, mobile applications, delivery networks and digital payment systems. Walmart responded by investing in e-commerce and technology while maintaining its enormous physical-store network.
The challenge was essentially one of scale: how can a retailer serve huge numbers of customers while managing prices, inventory, logistics and employee operations?
Duato and the Future of Healthcare
Duato’s challenge is different.
Johnson & Johnson operates in areas where product development can require years of research, clinical testing, regulatory review and specialized manufacturing. Its current business includes Innovative Medicine and MedTech, making scientific innovation central to its strategy.
The company reported $94.193 billion in full-year 2025 sales, while its 2026 outlook was raised after second-quarter results, according to Johnson & Johnson.
These figures illustrate the enormous scale of the organization Duato currently leads.
