Phil Ellis currently consults on health policy issues and analysis for clients in the pharmaceutical and insurance industries.

He has worked on health policy issues at Acumen LLC and UnitedHealth Group, under the Assistant Secretary for Planning and Evaluation at HHS, and at the Treasury Department.
