WISTA, founded more than 30 years ago, is a medium-sized, independent auditing and tax consulting firm based in Mannheim with branches in Speyer, Constance and Radolfzell on Lake Constance. 
Consulting services can not be reduced to isolated solutions, since most tasks are far too complex. That is why accountants, tax consultants, lawyers and management consultants work together across disciplines at WISTA. Because the company wants optimal results for its clients in all points! 
Since its foundation, WISTA advises and supports clients holistically through the WISTA consulting network.
