About me

My name is Heiko Mattmann and I am a passionate trustee and tax optimiser. Since completing my commercial apprenticeship, I have been able to continuously expand my knowledge in the field of accounting, taxes & auditing thanks to various jobs. After completing my vocational baccalaureate, I spent over 3 years in a local fiduciary office. Right from the start, I liked the subject so much that I knew that sooner or later I would set up a trust company myself. With this goal in mind, I immediately enrolled for a business administration degree with a specialisation in accounting, controlling and auditing at the ZHAW. However, as I had "only" been familiar with the fiduciary business until then, I wanted to broaden my horizons and gained instructive experience in international auditing companies, which gave me a new perspective on the figures. Finally, I took up a challenging position in controlling, where I was able to learn the financial planning & financial management of a company. The continuous optimisation of my clients' finances fascinates me and spurs me on every day to achieve above-average results. For a successful joint cooperation, however, the offene communication between my client and me is paramount. Because this is the only way to create the basis for trust, which in turn leads to success on both sides.
