Mickael Miettinen

Associate, Master of Laws

I advise both international and domestic clients in real estate transactions, investments and a broad spectrum of real estate-related matters.

Before joining Castrén & Snellman, I gained experience as a trainee at another law firm by specialising in real estate transactions, at a publicly listed Nordic energy company with a focus on contract law, and at the Ministry for Foreign Affairs, where I worked on sanctions law.

I hold a Master of Laws degree from the University of Helsinki and have further broadened my legal perspective through exchange studies at Trinity College Dublin in Ireland.
