Organisation
Managed by our Partners
Our 82 Partners hold an 80.5 percent stake in BDO, while our own pension fund holds the other 19.5 percent (as at 31.12.2020). Thomas Studhalter took over the lead at BDO as new CEO from 1 January 2021. He succeeds Werner Schiesser, who handed over the reins after ten successful years and at the end of his term of office. Due to limitations on the permissible terms of office, there were two further changes in the Executive Committee of BDO as at 1 January 2021. Markus Helbling, Head of Business Solutions, and Martin Nay, Head of Audit, stepped down from these roles and left the Executive Committee of BDO. Both remain with BDO and continue to support Business Solutions and Audit with their expertise and experience. They are succeeded by Marcel Rohrer as Head of Business Solutions and Beat Rüfenacht as Head of Audit.
