Daniel Tsai is the Assistant Secretary for MassHealth and Medicaid Director for the Commonwealth. Tsai was appointed in January 2015 by Governor Charlie Baker to oversee the state’s ~$15 billion Medicaid program, which covers one in four residents in the Commonwealth. In his role, Tsai is responsible for ensuring a robust and sustainable MassHealth program. That includes developing new policies, payment models, and operational processes that improve the way health care is delivered to 1.8 million low-and moderate-income individuals and individuals with disabilities.

Before joining HHS, Tsai was a Partner and leader in McKinsey & Company’s Healthcare Systems and Services practice. He has significant experience on design and implementation of innovative, state-wide health care payment systems for Medicaid, Medicare and Commercial populations, and has worked closely with multiple state Medicaid programs, private payers, and health services companies. He received a Bachelor of Arts in applied mathematics and economics from Harvard University.

Assistant Secretary Tsai and his wife live in Boston’s South End, where he volunteers at a local community health center.
