I serve as the Chair of the Board of Directors of Summa Health, which was acquired in October 2025 by Health Assurance Transformation Company (HATCo). HATCo is a platform created by global investment and transformation company General Catalyst to transform health systems into resilient, vibrant organizations in partnership with leading technology companies. Together, HATCo and Summa Health are embarking on a long-term vision to create a new, more proactive, accessible, and affordable system of community-based, lifelong healthcare.

My leadership spans both state-level healthcare policy and safety-net healthcare delivery. I bring a rare combination of executive capability and grounded empathy shaped by my time leading Boston Medical Center and most recently as Massachusetts Secretary of Health and Human Services, where I led the Executive Office of Health and Human Services (EOHHS), which provides access to medical and behavioral health care, long-term services and supports, and key nutritional and financial benefits. I represented a team of more than 21,000 staff across 11 agencies and the MassHealth system, who work daily to provide services and programs for nearly 1 in every 3 Massachusetts residents.

Prior to my appointment to Governor Healey’s cabinet, I served as CEO of the Boston Medical Center (BMC) health system for 13 years, overseeing an annual operating revenue of $6 billion. The BMC health system is comprised of a 514 bed, academic medical center that is the primary teaching affiliate of Boston University Chobanian & Avedisian School of Medicine, as well as WellSense Health Plan, a Medicaid Managed Care Organization, and Boston HealthNet, a network affiliation of 14 community health centers.

Before my time at BMC, I served as Executive Vice President and Chief Operating Officer of Brigham and Women’s Hospital, Chief Operating Officer for Novartis Institutes for Biomedical Research, and at Massachusetts General Hospital in positions including Senior Vice President of Medical Services and the MGH Cancer Center. Prior to my tenure at Mass General, I held positions in a number of New York City hospitals including Montefiore, Columbia Presbyterian Medical Center, Saint Luke’s – Roosevelt Hospital Center and the New York City Health and Hospitals Corporation.

I received my Bachelor of Arts and Master of Public Health degrees from Yale University. I have served as a member of the Board of the Federal Reserve Bank of Boston, the Boston Public Health Commission, the Massachusetts Hospital Association, the Association of American Medical Colleges, Pine Street Inn, and Yale University.
