Margaux Hall advises healthcare industry clients as they navigate the regulatory requirements of federal healthcare programs and the broader transformation of the regulatory landscape under the Affordable Care Act (ACA).

She was selected for a two-year healthcare law fellowship at Columbia Law School. In this role, she conducted extensive research and wrote on federal and state healthcare regulatory issues, including those emerging under the ACA. Margaux also served as a justice reform specialist with the World Bank's Legal Vice-Presidency in Sierra Leone, where she collaborated closely with the government and helped guide its work in the health sector.
