Heidi Pirhonen

Team Manager, Assistant Services

I work at Castrén & Snellman as a supervising assistant and as an assistant in our Insolvency service. I find working as a team supervisor very rewarding, and it is great to support and work as part of a highly skilled team of assistants. My dual role offers me a wide range of tasks and the opportunity of participate in many different kinds of projects.

I have years of experience as an assistant in law firms, and have worked as a team supervisor and assistant at C&S since 2013. I have worked in law firms since 2007, so you could say I am smitten with the field. I have a BBA with a specialisation in legal expertise.

I am a positive, helpful, empathetic and friendly person. I am quick to take action and am good at keeping a handle on things even when work gets hectic.
