Tuula Cheema

Fiduciary Consultant

My professional life started in corporate archives and academic libraries in Finland and later continued in various archive centers of a multinational financial institution in London. Organizing knowledge, i.e. cataloging, classifying and indexing various materials to make them accessible to end users, interested me a lot. I was also the owner of a small retail store for several years and experienced firsthand what it meant to be professionally self-employed. That’s also when my interest in accounting was sparked. For the past 12 years, I have been working for Borsoi AG as a clerk, preparing tax returns and business accounts for audit. In addition, I perform accounting tasks. I am proud/glad to work with competent and dedicated colleagues.


In my free time, I engage in TaiChi, QiQong, Argentine Tango, and learn French and Japanese.
