On October 6, 2026, Highmark Health made a pivotal announcement regarding its leadership structure, appointing Karen Hanlon as its next Chief Executive Officer (CEO) and President, effective January 1, 2027. This appointment is significant, marking Hanlon as the first female to hold the CEO position in the organization's rich history. David Holmberg, who has been at the helm as CEO since 2014, will transition to the role of Executive Chairman. The Board of Directors expressed strong confidence in Hanlon's leadership capabilities as she takes on the responsibility for directing Highmark Health's strategy, operations, growth, and performance.
Karen Hanlon has been with Highmark for nearly 30 years. She joined the organization in 1997, beginning her career in public accounting at KPMG. Over the years, she has ascended through various leadership roles, demonstrating her expertise, particularly in financial management. Her appointment as Chief Financial Officer in 2014 saw her drive significant improvements in financial performance, leading to record revenue growth. This growth has included expanding the organization from approximately $17 billion in revenue in 2014 to a projected nearly $35 billion in 2026.
In her recent role as President, Hanlon oversaw substantial organizational transformations, including crucial affiliations that expanded Highmark's health plans in five additional states. Innovations under her stewardship included the acquisition and transition of Gateway Health to Highmark Wholecare, which diversified Highmark's portfolio by adding Medicaid products. Furthermore, she played an essential role in launching the Allegheny Health Network (AHN) and successfully led AHN's inaugural $1 billion tax-exempt bond financing aimed at stabilizing its long-term capital and fostering continued growth.
Expressing her thoughts on this transition, Hanlon stated, “As healthcare continues to evolve, our focus remains clear – making healthcare more affordable, simpler, and more effective for the communities we serve.” Her commitment to advancing Highmark’s “Living Health” strategy highlights a renewed direction for the organization, ensuring that it continues to deliver exceptional health experiences and transformative care.
Greg Jordan, chair of Highmark Health’s Board, commended Holmberg's brave and consistent leadership over the past twelve years, ensuring that his guidance would facilitate a seamless transition while supporting the strategic priorities of the company moving forward. As Executive Chairman, Holmberg will collaborate closely with Hanlon and the Board, thus ensuring that the organization continues on its growth trajectory.
Hanlon's leadership has also earned her numerous accolades, including recognition from the Pittsburgh Business Times and Modern Healthcare. Her operational expertise and unwavering commitment to the people served by Highmark Health have significantly shaped the organization's current standing. Moving forward, her vision aims to lead Highmark Health into a future characterized by improved health services that prioritize accessibility and efficiency.
