Today's Treuhand A. Willimann GmbH was founded on May 1, 1974. After a wide range of training in small and medium-sized enterprises and almost ten years as a tax expert at the Cantonal Tax Administration in Lucerne, Alois Willimann, a federally certified controller/accountant, decided to become self-employed.

Because of his work as an assessor for the tax authorities, Alois Willimann saw a gap in the medical profession in terms of accounting and tax advice. Over the years, Treuhand A. Willimann GmbH developed into one of the largest medical fiduciary companies in Central Switzerland.  
The constantly updated doctors' experience figures are very popular and useful with existing clients and practice planners. In addition, almost all industries from the trades and retail sector, as well as restaurants and hotels, are supported.

In addition to the company founder, his son Rolf Willimann - holder of the federal certificate for trustees and the federal certificate for real estate managers - has been actively involved in the management of the company for many years.

Since market conditions are constantly changing, Treuhand A. Willimann GmbH transformed its business into a legal entity in 2004.

Treuhand A. Willimann GmbH sees itself as a competent all-rounder for small and medium-sized companies. Specialists are called in on a case-by-case basis.
