Mr. Thomas leads Sutter Health, one of the nation’s largest nonprofit health systems, where in 2025 he guided the organization to care for more than 3.6 million patients, representing an increase of more than 110,000 from the prior year. During this time, the system also opened or expanded 31 ambulatory care sites, enabled 1.1 million additional online appointments, and achieved 65% digital patient engagement across Northern and Central California. A cornerstone of his growth strategy has been one of the most effective clinician recruitment efforts in the industry, growing Sutter’s aligned medical groups from 4,331 to 6,144 clinicians between 2022 and 2025 for a nearly 42% increase, while putting the system on track to become the largest community-based medical training program in Northern California, with a goal of 1,000 residents and fellows by 2030. Quality outcomes have strengthened meaningfully under his leadership, with 16 system hospitals earning Leapfrog “A” safety grades in 2025, the system’s strongest performance to date, alongside delivery of more than 917,000 additional cancer screenings compared to the prior year. Philanthropy reached historic levels in 2025 with $242 million raised, including a largest-in-system-history gift of $110 million to expand access in California’s Greater Silicon Valley. Mr. Thomas has served on the American Hospital Association’s board of trustees and chaired its health systems governing council. He has also served on the Medicare payment advisory commission, continues to advise Congress on Medicare-related issues, and is a fellow of the American College of Healthcare Executives. He was named 2026 “CEO of the Year” by Press Ganey.
