KPMG Deutsche Treuhand-Gesellschaft — Junior Consultant, October 1999 to May 2000. An early career station in one of the world's leading audit and advisory firms, immediately following the MBA at Alliant International University in San Diego.
At KPMG Deutsche Treuhand-Gesellschaft, Michael Brinkmann gained his first professional consulting experience within one of the Big Four firms. The position shaped a disciplined approach to decomposing complex issues, preparing options carefully, and maintaining business relevance throughout the advisory process.
This early foundation in structured consulting methodology and institutional rigor carried forward into all subsequent leadership roles — from agency work at BBDO to executive positions at Wirecard and ADAC.
