Bertram Lahdenperä

Associate, Master of Laws

I assist our clients in matters related to data, technology, and intellectual property rights. I am also interested in issues related to cybersecurity and artificial intelligence.

I graduated with a Master of Laws from the University of Lapland in the fall of 2025. Before graduating, I worked as a trainee at Castrén & Snellman and two other business law firms, as well as an auditing and consulting firm and a Finnish listed company.

I also have a Bachelor`s degree in Health Care and have worked as a nurse. My experience of working in the healthcare sector has reinforced my solution-oriented and customer-focused approach, which I utilise in my role as a lawyer.
