Samuli Salminen

Senior Associate, Member of the Finnish Bar

I assist our domestic and international clients in assignments related to data and technology. I advise our clients in various contract and transaction arrangements as well as in various digitalisation and outsourcing projects. In addition to contract law, my personal interests relate to data protection and IPR law.

I graduated from the University of Lapland in 2021. I have also gained international experience studying law at the University of Gothenburg (School of Business, Economics and Law). Prior to my graduation, I worked at Castrén & Snellman in various trainee positions. I have also worked in another international business law firm. My versatile and international experience in the field of business law makes me a business-oriented and versatile lawyer.

I have a practical approach towards assignments. I think it is very important to understand our clients’ businesses to find the best solutions for their needs.
