Longtime Humana executive George Renaudin, insurance segment president, plans to retire by next summer, the insurer announced Tuesday.
The insurer named Amazon healthcare executive Aaron Martin as his successor with plans for Martin to initially lead Humana's Medicare Advantage (MA) business beginning in January.
Renaudin, who is also a member of Humana’s enterprise leadership team, played a pivotal role in establishing and growing Humana’s MA and Medicaid programs during his 29-year career at the company, the insurer said in a press release.
“George has contributed greatly to Humana’s success, driving the growth of these programs, and shaping our value-based care strategy,” said Humana President and CEO Jim Rechtin in a statement. “He has been instrumental in positioning us for long-term success, with sustained membership growth and consistent high-quality care. We are grateful for his commitment to a smooth transition that ensures continuity for our people, partners and upcoming priorities, including next year’s annual bid process.”
“I am deeply proud of the work we’ve done in my nearly three decades at Humana, and after much thought and planning, I am confident that this is the right time for me to announce my retirement,” said Renaudin in a statement. “We have built a strong team across our Medicare Advantage, Medicaid, and Specialty businesses, making them well positioned to deliver on our strategy while driving value for years to come.”
Martin, who spent the past four years as vice president of healthcare at Amazon, will initially join Humana in January as president of MA and will serve as a member of the company's enterprise leadership team.
In the newly created role, Martin will report jointly to Renaudin and Rechtin. The new role will consolidate Humana’s MA operations under a single leader to "drive operational excellence across the businesses," Humana said in the press release.
Following Renaudin’s retirement, Martin will assume the role of president of the insurance segment, and John Barger will be promoted to the role of president of MA, reporting directly to Martin.
Rechtin said Martin's experience in applying technology and a consumer-centric approach will strengthen Humana's ability to serve members and deliver better outcomes.
"Aaron’s proven ability to lead healthcare organizations through periods of transformation will position him to provide immediate and impactful oversight of our talented and experienced insurance team. At the same time, we are also pleased that a seasoned and disciplined Humana leader such as John will ultimately be leading our Medicare Advantage business. We are confident that with these appointments, our insurance team will continue to advance our efforts to become a worldclass, consumer healthcare company and position Humana for continued shareholder value creation," he said.
Barger is currently president of Humana's Medicaid and dual eligible programs and has more than 25 years of experience at the company, including more than a decade supporting the MA business.
After retiring, Renaudin will serve as a strategic advisor to the company through at least the end of 2026 to ensure a thoughtful transition, Humana said.
At Amazon, Martin oversaw strategic partnerships, marketing and the company’s telehealth and chronic conditions programs. Prior to Amazon, he spent eight years at Washington-based health system Providence as executive vice president and chief digital officer as well as managing general partner for Providence Ventures. He joined Providence after a previous stint at Amazon, where he worked on the company's Kindle e-reader and print-on-demand platforms.
Humana had 8.2 million Medicare members as of June 30, 2025. About 5.8 million of those members are enrolled in a MA plan, according to the company.
Like its peers in the insurance business, Humana has felt the sting of elevated medical costs in 2025. The company has been investing in improvements to shore up its core MA business.
A major focus on Humana's third-quarter earnings call was the star ratings and how the payer can bounce back from a lackluster outing in the latest scores, with just 20% of its members enrolled in plans with at least four stars.
