Natalie served as Minister of Finance of Ukraine (2014-16) at one of the most difficult times in Ukraine’s history, rocked by a deep recession, Russia's initial occupation and war. She led the successful negotiation and implementation of the largest IMF program in history, including a complex sovereign debt restructuring, reduction of budget deficits, introduction of budgetary transparency, improved corporate governance at state-owned banks, and reduction of monopolistic practices. Natalie served five years (2017-2022) as the Executive Director of the Financial Oversight and Management Board for Puerto Rico. She led the sustainable exit from the largest municipal bankruptcy in U.S. history, while restoring the Island’s fiscal health. Notwithstanding environmental and political instability, she focused limited budgetary resources on improving critical public services, while strengthening budgetary practices and financial reporting. Earlier she spent two decades in private equity, as CEO of Horizon Capital and Western NIS Enterprise Fund, fund managers with over $600 million under management.
