Matter Health Appoints Michael Scarbrough as Chief Executive Officer

Founder & CEO Mason Mercy to Transition to President/Chief Strategy Officer as Matter Health Strengthens Leadership for National Expansion to meet rising demand

NASHVILLE, Tenn.--(BUSINESS WIRE)--Matter Health, a value-based medical group delivering comprehensive care inside affordable senior housing communities, today announced the appointment of Michael Scarbrough as Chief Executive Officer, effective December 1, 2025. Founder Mason Mercy will continue to serve on the board and transition to President/Chief Strategy Officer, where he will focus on enterprise strategy and all aspects of external growth.

The leadership evolution reflects Matter’s strong growth trajectory and expanding national footprint. The company now serves thousands of dual-eligible seniors across multiple states through its embedded care model, which integrates clinical, behavioral, and social services directly within where patients live.

“Matter’s mission to deliver high-quality care to underserved seniors is both urgent and inspiring. The model they’ve built is truly unique and will continue to improve lives while driving the outcomes necessary to sustain growth,” said Michael Scarbrough, Chief Executive Officer of Matter Health. “I’m honored to partner with Mason and the Matter team to scale this model nationwide and continue improving the lives of the patients and communities we serve.”

Scarbrough joins Matter Health with more than 30 years of experience building and scaling national, value-based care platforms. He most recently served as President and Chief Operating Officer at InnovAge, the nation’s largest operator of PACE programs and a publicly traded company. From 2018 to 2022, he served in the same role at Prospero Health, an organization he co-founded and scaled to 29 states before its acquisition by Optum. He later served as CEO of Optum at Home from 2022 to 2023 and has also held senior executive roles at Anthem/Elevance and Amerigroup.

“Matter has proven that meeting seniors where they live improves outcomes, satisfaction, and costs — giving us the opportunity to grow nationally over a short time horizon to reach more seniors and drive our mission forward,” said Mason Mercy, Founder and President. “As we scale into new states and deepen partnerships with national payers and housing organizations, Michael brings the operational experience and leadership needed to guide Matter through the next phase of our growth.”

Under Mercy’s leadership, Matter Health has grown from a concept in Nashville to a rapidly scaling national platform backed by leading investors and payer partnerships. The company plans to enter several new states in 2026 and expects to more than triple its community footprint in the coming year.
