AmeriHealth Caritas Names Gregg MacDonald Interim President

AmeriHealth Caritas today announced that Gregg MacDonald has been appointed interim president, effective immediately.

The leadership transition follows the August announcement of Kelly Munson's expanded role as president and chief executive officer of Independence Health Group. AmeriHealth Caritas, a national leader in Medicaid managed care and other health solutions, is jointly owned by Independence Health Group and Blue Cross Blue Shield of Michigan.

Munson will continue to provide oversight of AmeriHealth Caritas to ensure continuity and organizational alignment. She had served as president and CEO of AmeriHealth Caritas since February 2024.

MacDonald was serving as AmeriHealth Caritas' executive vice president, specialty products and network. He has played a key role in advancing the company's specialty products portfolio and strengthening its provider networks.

MacDonald brought nearly four decades of healthcare leadership experience to AmeriHealth Caritas when he joined the company in September 2024 from Centene Corporation. He also previously held leadership roles at WellCare Health Plans; UnitedHealth Group; Cigna Healthcare; Aetna, a CVS Health Company; and Blue Cross Blue Shield of Delaware.

"Gregg is a proven leader with the wide range of experience, commitment, and vision to guide AmeriHealth Caritas through this important transition," Munson said. "He holds deep expertise in leading large, national and regional P & Ls, acquisitions and networks across Medicaid, Medicare, ACA and commercial product lines. We're excited for Gregg to lead us forward in ensuring that AmeriHealth Caritas remains as strong and successful as ever."

MacDonald will focus on ensuring operational continuity while advancing the company's growth strategy and enhancing the member experience.

"It is an honor to step into this role and to continue building on the strong foundation we have established," said MacDonald. "AmeriHealth Caritas has an extraordinary mission to expand access and improve health outcomes. I look forward to working alongside Kelly and our dedicated associates to advance our shared mission."

Under Munson's leadership, AmeriHealth Caritas has progressed its growth strategy, reshaped its leadership structure, and positioned the company for long-term success. The organization remains deeply committed to its associates, members, and community partners.
