OAKLAND, Calif., Aug. 26, 2025 /PRNewswire-HISPANIC PR WIRE/ — Blue Shield of California today announced Mike Stuart as its new president and chief executive officer. A longtime executive and former chief financial officer of the nonprofit health plan, Stuart brings more than two decades of leadership experience in health care that will further Blue Shield’s mission of providing access to high-quality care that’s sustainably affordable for all.

“Mike Stuart is the right leader at the right time for Blue Shield of California,” said Kristina Leslie, chair of the Blue Shield of California board of directors. “He has a deep understanding of our mission, our members and the complex healthcare landscape we operate in. Mike’s financial expertise, collaborative approach and long-standing commitment to the nonprofit values that guide us make him uniquely positioned to lead our organization forward.” 

As chief financial officer since 2022, Stuart has helped guide the organization through some of the most complex challenges the healthcare industry has faced. He has been instrumental in helping to make health care more affordable for Blue Shield’s members, supporting provider partnerships and ensuring financial sustainability of the health plan while staying true to the company’s nonprofit mission.   

“Our industry is facing extraordinary challenges — from rising costs to regulatory shifts and increasing demands for equity and access,” Leslie said. “In this environment, we need a leader who not only understands the complexity of the healthcare system but also has the conviction and capability to drive real, sustainable change. Mike brings exactly that.” 

As president and CEO, Stuart will lead over 6,500 employees who serve 6 million members with health, dental, vision, Medicaid and Medicare health service plans in California and beyond. He is also deeply committed to advancing the organization’s values across teams and partnerships, including recent collaborations to serve over 750,000 active-duty military members and their families, and expand our offerings for CalPERS members.

“I am honored to lead Blue Shield of California at such a critical moment for our state and industry,” said Stuart. “We have a responsibility as a nonprofit health plan to lead with integrity, partner with purpose and ensure care is both accessible and affordable. I’m proud to work alongside our talented leaders across the Ascendiun family of companies to build a healthcare system that works better for everyone.” 

Stuart’s experience spans finance, operations and systemwide transformation. Prior to joining Blue Shield, he spent 11 years in senior leadership roles at the Daughters of Charity Health System, giving him firsthand knowledge of the challenges providers face and the importance of aligning incentives to improve outcomes and access for patients.
