AArete Names Healthcare Executive Pam Shipley as Chief Executive Officer

Global consulting firm’s founder Loren Trimble to step down after 18 years of growth and recognized excellence

CHICAGO–(BUSINESS WIRE)–AArete, a leading global management and technology consulting firm, announced today the appointment of Pam Shipley as chief executive officer. A Fortune 25 healthcare executive with more than 30 years of experience, Shipley succeeds AArete Founder Loren Trimble, who will transition from his role as CEO to board member.

Shipley joins AArete from Centene Corporation, a leading managed care organization, in which she most recently served as chief strategy officer. She spent nearly 14 years at Centene over two tenures where she held multiple CEO roles in Georgia, Missouri and Mississippi and led digital transformation and market expansion across more than 15 markets. 

Over her three-decade career in healthcare, Shipley has built a reputation as an executive who combines deep operational expertise with technology-enabled innovation, including senior leadership roles at Kaiser Permanente and Sharecare spanning healthcare technology, provider operations and consulting-driven transformation. Recognized for her ability to align strategy, technology and operations to drive growth, Shipley brings to AArete a track record of helping organizations navigate complex transformations in highly regulated, technology-driven environments.

“As a former client, I have worked closely with AArete throughout my career and witnessed firsthand the firm’s ability to accelerate growth and drive results,” Shipley said. “My work has always been personal to me. I’ve focused on making healthcare more affordable and effective for the people and communities served by health plans. AArete’s talented team and proven solutions are uniquely positioned to help clients do exactly that. I’m honored to build on Loren’s legacy and excited to continue delivering value for our clients.”

AArete drives profitability improvement, digital transformation and AI solutions for clients across a range of industries, including the healthcare payer segment, which has become the firm’s signature strength. The firm advises on U.S. health plans of every type, including Medicaid, Medicare, ACA Marketplace and commercial, helping clients manage the total cost of care and expand affordability without sacrificing quality or the member experience. In 2025, AArete secured a strategic investment from Parthenon Capital, a growth-oriented private equity firm with deep experience backing healthcare solutions and technology companies, further strengthening the firm’s continued growth.

“What we’ve built at AArete would not be possible without a culture built on integrity, excellence and care for the people we serve, and I’m proud that Pam will continue that legacy,” Trimble said. “She’s a purpose-driven leader whose passion for people and delivering results for clients reflects the values of the firm. I am confident she will lead AArete into its next chapter and build on its success.”

Trimble established AArete in 2008 with the goal of building a consulting firm that nurtures long-term client partnerships. Under his leadership, AArete grew into a global firm with more than 500 team members, earning recognition as a Forbes World’s Best Management Consulting Firm for four consecutive years and a USA Today Top Workplaces Award, underscoring the firm’s strong culture and people-first approach.

“AArete has become an essential partner to many of the nation’s leading health plans, and Pam is exactly the right leader to build on the firm’s momentum going forward,” said Dan Killeen, partner at Parthenon Capital. “Her payer expertise and track record of driving growth and performance make her uniquely suited to lead AArete into the future. We are grateful to Loren for his visionary leadership and look forward to his continued engagement as a member of the board.”
