As one of the earliest joint venture health plans in the country, Banner|Aetna has successfully aligned payer and provider incentives to drive down costs, improve quality and enhance the member experience. Under Grote’s leadership, the Banner|Aetna performance network has achieved savings of approximately 15%. The plan has also implemented innovative solutions for diabetes care and virtual care and initiatives like “frictionless billing”, which streamlines the health care billing and payment process for plan members.

Grote possesses more than three decades of experience in the health insurance industry. Immediately prior to his role as Banner|Aetna CEO, he managed Aetna’s operations in Arizona and New Mexico, and oversaw the west territory markets.

Thanks to the deep expertise gained through these efforts, Grote has secured his position as a thought leader and he is regularly invited to speak at national industry events and featured in some of health care’s most influential publications. His outstanding leadership and ambitious vision for change in the industry has been recognized by the Phoenix Business Journal who named him “Most Admired Leader” in 2023. Grote was a finalist in AZ Big Media’s Champion of Change “Healthcare Leader of the Year” award and is also listed as a “Phoenix Titan 100” by Titan CEO, where he's been appointed to serve on the Phoenix Titan 100 Board.
