Byrnes brings more than 15 years of experience in operations and strategy, including over a decade at CVS Health/Aetna, where he led the development and execution of strategic priorities across multiple functions spanning Government Affairs, Consumer Products, and Enterprise Strategy. He most recently served as Executive Director of Clinical and Network Operations, leading strategic improvements in business processes, care delivery, and provider collaboration across healthcare systems nationwide.
“We’re thrilled to welcome John to our executive team,” said Victoria Coley, Banner|Aetna CEO. “His deep understanding of healthcare operations and ability to translate strategy into execution will accelerate our mission to deliver quality, cost-effective care to Arizona communities. John’s expertise is exactly what we need as we evolve for the future.”
Through this executive leadership addition, Banner|Aetna expects to provide its members with smoother care experiences and more personalized support, while brokers and provider partners should benefit from streamlined operations.
