Pittsburgh-based Duquesne Light Holdings (DLH) and Duquesne Light Co. (DLC) named a new vice chairman of the boards of directors for both companies.
As of Aug. 1, David Holmberg, CEO of Highmark Health, took on his new roles, bringing nearly two decades of executive leadership experience in the health care and insurance industries.
“I am honored to join the boards of directors of Duquesne Light Holdings and Duquesne Light Company as vice chairman,” said Holmberg. “Duquesne Light has been a pillar of our community for more than 100 years, and its long-standing commitment to serving customers should serve as an inspiration to other organizations in our region.”
As CEO of the $32 billion Highmark Health blended health organization, Holmberg oversees one of the nation’s largest Blue Cross Blue Shield insurers and a growing regional hospital and physician network serving millions of customers nationwide.
Under Holmberg’s leadership, Highmark Health has grown annual revenue from $15 billion in 2013 to $32 billion in 2025 while expanding access to care, investing in digital innovation, and strengthening its integrated payer-provider model.
“David is a distinguished executive whose track record of leading complex organizations, driving innovation, and delivering long-term growth makes him an outstanding addition to our boards of directors,” said DLH and DLC Board Chairman Joseph Guyaux. “His expertise in strategic leadership, customer experience, and stakeholder engagement will strengthen our ability to guide the company through a rapidly evolving energy landscape.”
Since joining Highmark in 2007, Holmberg has held a series of executive leadership positions, including president of Diversified Businesses and CEO roles overseeing HM Insurance Group, United Concordia Dental, and Visionworks.
“David’s customer-focused mindset and ability to navigate change in dynamic industries will be tremendous assets to Duquesne Light,” said Kevin Walker, president and CEO of DLH and DLC, and a member of both boards. “He understands the importance of delivering for customers, building strong relationships, and investing in the communities we serve.”
Holmberg is chairman of Highmark Inc. and previously served as chairman of America’s Health Insurance Plans and the Blue Cross Blue Shield Association.
He also serves as chairman of The Allegheny Conference on Community Development and The Pittsburgh Cultural Trust and sits on the boards of directors of Allegheny Health Network and VSP Vision.
“I look forward to working with my fellow board members and company leadership to support DLC’s continued success and its mission to deliver safe, reliable, and innovative energy solutions,” Holmberg said.
