About WADSACK

Our history: Over 40 Years of Experience and Innovation in Fiduciary Services

On July 1, 1983, Hans Wadsack laid the foundation for what has become a leading company in fiduciary and tax consulting with the establishment of the sole proprietorship “Hans Wadsack, Fiduciary and Tax Consulting Office” in Zug. By 1989, the business evolved into the limited partnership wadsack & co. treuhandgesellschaft, setting the stage for future growth.

In the following years, we continuously expanded our expertise and market position:

  • 2002: Acquisition of Schlumpf & Partner Treuhand AG, Zug
  • 2010: Acquisition of WEY & SPIESS Treuhand und Revisions AG, Zug

With the transformation into a public limited company in May 2018 and the successful succession planning of Hans Wadsack, we laid the foundation for today’s Wadsack Zug AG. During this restructuring, our previous subsidiaries were integrated, allowing us to operate under one strong brand name, WADSACK.
