Sara Koski

I have been mostly in contact with counsel Sara Koski who is a very knowledgeable, experienced, multi-lingual lawyer who always puts the client first and is ready to go the extra mile to help the client achieve an optimal or even better end result. She is among the best connoisseurs of French compliance legislation and regulations and has repeatedly helped large corporations and mid-sized companies to navigate their way out of the labyrinth of often conflicting legal obligations in several countries and continents.

Sara assists clients in a broad range of compliance matters including design and implementation of compliance programs, carrying out risk mappings, anti-corruption due diligence and internal investigations regarding both general anti-corruption regulations and in the life sciences sector.

Sara began her career with compliance & risk management and life sciences teams in the Paris office of a leading American law firm. She has developed an in-depth experience in relation to the investigation and prevention of corruption and related issues in France (in particular, "Sapin II" Law anti-corruption measures, French "Duty of Vigilance" Law, Registers of lobbyists and beneficial owners, etc.).

Her experience also covers compliance aspects in the life sciences sector (French "Anti-Gift Law" and "Sunshine Act", sector specific ethical guidance and rules adopted by SNITEM, LEEM MedTech Europe, EFPIA, etc.).
