In his new role at Optum, Mancuso is positioned to bring together his experience in healthcare operations, clinical strategy, population health, provider networks, financial management, and organizational transformation to support the continued growth and performance of American Health Network.
A New Leadership Chapter at Optum
Mancuso began his latest chapter in August 2026, joining Optum as Chief Operating Officer of American Health Network in Indiana.
The appointment represents a natural progression for an executive whose career has consistently centered on healthcare delivery and operational leadership. His background spans health plans, provider organizations, primary care models, healthcare technology, and transformation-focused businesses.
As healthcare organizations continue to navigate evolving consumer expectations, value-based care models, affordability pressures, clinical quality priorities, and the need for coordinated delivery, operational leadership has become increasingly important.
Mancuso’s experience across these dimensions provides a broad foundation for his new responsibilities at American Health Network.
Bringing Strategic Healthcare Experience to American Health Network
As Chief Operating Officer, Mancuso enters the role with a track record of leading healthcare businesses and markets through periods of growth, transformation, and operational evolution.
His career has included responsibility for profit and loss management, clinical operations, provider networks, Medicare Advantage, population health, strategic planning, market development, and organizational performance.

From transformation consulting and network development to market presidency, regional leadership, clinical operations, and COO responsibilities, his career has consistently involved translating strategy into measurable execution.
