Jeff Martin and David Cordani are American executives who lead, or recently led, two of the country’s most influential companies. Jeffrey W. Martin is chairman and CEO of Sempra, a Fortune 500 energy infrastructure company. David M. Cordani led The Cigna Group as CEO for nearly 17 years. They work in different industries, and I found no documented business partnership between them. Their careers still share clear themes: long climbs inside one organization, financial discipline, and steady leadership through change. This biography profiles both men using company announcements, filings, and news reports. It shows who they are, how they rose, and what their stories can teach readers.
A Quick Note on Identity and Sources
The name Jeff Martin belongs to many public figures, including a Canadian rock musician, a former NBA player, and a Simpsons writer. This article covers Jeffrey W. Martin, the energy executive, because he is the business leader most naturally profiled beside a corporate figure like Cordani. If you were searching for a different Jeff Martin, the details below will not apply. I also found no evidence of a joint venture, shared board seat, or partnership linking the two men, so they appear here as parallel profiles. Titles and figures can change, so confirm current details on each company’s official website before citing them elsewhere.
Jeff Martin: Profile at a Glance
Jeffrey Walker Martin leads one of North America’s largest energy infrastructure companies. Sempra says he oversees a $48 billion capital campaign, the largest in its history, and leads about 20,000 employees. Sempra’s holdings include SDG&E, SoCalGas, Oncor, and Sempra Infrastructure. Together these serve the daily energy needs of millions of customers across California, Texas, and Mexico. Martin also sits on the boards of Oncor Electric Delivery and the University of San Diego. His public profile is that of a finance-minded operator who rose through the ranks. He is known less for celebrity than for steady, strategy-driven management of capital-intensive businesses.
Education and Early Career
Reported profiles say Martin holds degrees from the U.S. Military Academy at West Point, the University of Texas at Austin, and the University of Miami. Before reaching the executive suite, he built a varied résumé. He worked as an attorney at Snell & Wilmer and served as president of TruePricing, Inc. He was also chief financial officer of NewEnergy, Inc. That mix of legal training, finance, and operating experience later proved valuable at Sempra. Personal details such as his birthplace and family life are not well documented in public sources, so this profile focuses on his verifiable professional record.
Joining Sempra in 2004
Martin first joined Sempra Energy in 2004 as a principal in the mergers and acquisitions group. That deal-making role gave him a close view of how the company bought, sold, and reshaped its businesses. He later became vice president of investor relations. That job required translating complex strategy into clear messages for Wall Street, a skill that shapes how he communicates today. Starting in M&A and investor relations meant he learned the company’s financial architecture before running any single division. For readers studying how executives build credibility, this early phase shows the value of understanding capital markets from the inside.
Rising Through SDG&E and the CFO Role
Martin’s operating roles came next, and they grew steadily. From 2010 through 2013, he was president and CEO of Sempra U.S. Gas & Power and Sempra Generation, the predecessors of Sempra’s renewable energy and midstream businesses. From 2014 through 2016, he was CEO of San Diego Gas & Electric, adding the chairman and president titles in 2015. He became executive vice president and chief financial officer of Sempra Energy in January 2017. Running a regulated utility and then the company’s finances gave him a rare mix of customer-facing and balance-sheet experience.
Becoming CEO and Chairman of Sempra
Sempra’s board elected Martin to succeed Debra Reed as CEO, and Reed remained executive chairman until her December 2018 retirement. He assumed the CEO role in May 2018. The board then elected him chairman, effective December 1, 2018, when he was 56. The board said he had already outlined a new strategy to focus on growing the company’s North American business. That decision to concentrate on North America and sharpen the portfolio became the defining thread of his tenure.
Jeff Martin’s Leadership Style and Strategy
Martin’s approach centers on infrastructure, reliability, and the energy transition. Sempra describes his mission as making the company North America’s premier energy infrastructure business, with investments aimed at electrification and decarbonization. He tends to speak in terms of long-term capital plans rather than quick wins, which fits an industry where assets last for decades. His background in finance and investor relations shows in his emphasis on disciplined capital allocation. Observers often describe his style as measured and analytical. Compared with more flamboyant executives, he leads through process, planning, and clear communication with regulators, investors, and employees.
David Cordani: Profile at a Glance
David M. Cordani was born on February 10, 1966, and grew up in Connecticut. He became one of the best-known leaders in American health care by guiding The Cigna Group through a major transformation. He has been Chairman since January 2022. Under his leadership, Cigna expanded beyond traditional insurance into a broad health services model that includes Cigna Healthcare and Evernorth. His public statements consistently stress affordability, personalization, and the idea that the health care status quo is unsustainable. This section traces how a long-serving insider became the face of a Fortune 100 company.
Joining Cigna in 1991
David Cordani has been with Cigna since 1991. Like Jeff Martin, he built his career inside a single organization rather than hopping between employers. That long tenure gave him deep knowledge of the company’s culture, customers, and operations. Early in his career he held roles across marketing and customer segments. He previously served as senior vice president of customer segments and marketing. That grounding in how customers choose and use health benefits shaped his later strategy, which focused on making coverage easier to understand and more affordable for employers and individuals.
Climbing to President and COO
Cordani’s rise accelerated in the mid-2000s. He became president of Cigna HealthCare in July 2005. In June 2008, he was named president and chief operating officer of Cigna, taking responsibility for group disability and life insurance, international businesses, and Cigna HealthCare. Running that portfolio prepared him for the top job. It also exposed him to the global side of the business, which later informed the company’s international strategy. By the time succession planning began, the board could point to years of measurable results under his oversight.
Nearly 17 Years as CEO
Cordani succeeded H. Edward Hanway as president and CEO, a transition announced in 2009 and effective at the start of 2010. That timing explains why some profiles say 2009 and others say 2010. He ultimately led the company for nearly 17 years. During that period Cigna evolved into a very different company, building out Evernorth and a wider services portfolio. Early in his tenure he was also noted as an accomplished triathlete who had completed two international Ironman competitions. That discipline and endurance became part of his leadership brand.

The 2026 Succession: From CEO to Executive Chair
On March 3, 2026, The Cigna Group announced that Cordani would retire as CEO effective July 1, 2026, and become executive chair of the board. Brian Evanko, then president and COO, succeeded him. The company said the two would work together through the transition, and it reaffirmed its 2026 financial outlook. Cordani called leading the company “the privilege of a lifetime.” His shift to executive chair means he remains influential at Cigna, though day-to-day leadership now sits with his successor. the cigna group announces president coo brian evanko to succeed david m cordani as chief executive officer +3
Jeff Martin and David Cordani: Side-by-Side Comparison
Placing Jeff Martin and David Cordani next to each other reveals useful contrasts. Martin leads Sempra, an energy infrastructure company, and became CEO in 2018 after joining in 2004. Cordani joined Cigna in 1991, became CEO around 2010, and stepped aside as CEO in 2026. Martin’s path ran through finance, mergers, and utility operations, while Cordani’s ran through marketing, health plans, and global business lines. Both held the chairman title alongside the top job at some point. Both also succeeded respected predecessors, and both emphasized strategy over spectacle. The comparison shows that internal development remains a proven route to the corner office.
Leadership Lessons from Two Corporate Leaders
Several lessons emerge from these careers. First, patience pays: both executives spent years, even decades, mastering one organization before leading it. Second, cross-functional experience matters. Martin moved between M&A, investor relations, utilities, and finance, while Cordani moved across marketing, operations, and international businesses. Third, clear strategy beats constant reinvention. Martin’s North America focus and Cordani’s push toward integrated health services gave their companies a consistent direction. Finally, planned succession protects stability. Cigna’s long handover period shows how a transition can be managed deliberately, which investors, employees, and customers generally value.
Industry Impact: Energy and Health Care
The industries these leaders shape touch nearly every household. Sempra’s utilities and infrastructure assets deliver electricity and natural gas, and the company describes the energy transition as central to its future. Cigna’s businesses help determine how millions of Americans access care, pharmacy services, and insurance coverage. Both sectors face heavy regulation, rising costs, and public scrutiny, so leadership decisions carry real consequences for customers and communities.

Conclusion
The stories of Jeff Martin and David Cordani show how patient, internally developed leadership can steer large, complex companies. Martin went from M&A and investor relations to chairman and CEO of Sempra, while Cordani went from a 1991 Cigna hire to nearly 17 years as CEO and a new role as executive chair. Their industries differ, but their paths point to the same lessons: master the fundamentals, build broad experience, communicate clearly, and plan transitions carefully. Because titles and company details change, verify current information through official sources. For anyone studying executive careers, these two profiles are practical case studies in long-term leadership.
