Eszter Valkó

Director of Finance and Operations

Ms Valkó started her professional career at Arthur Andersen. She soon gained the British and a couple of years later the Hungarian chartered accountancy qualification. She worked for Arthur Andersen in Budapest and London, and was the finance director of a Dutch off-shore entity. Later, Ms Valkó became a project manager in MOL's Accounting and Tax department, in charge of the day-to-day cooperation with the accounting service provider, employing 250 employees.

Ms Valkó finds great pleasure in a quiet evening in with a good book just as much as she enjoys an evening out with her friends. She is the mother of two teenagers and practises yoga in her free time.
