Fast-growing German firm Haarmann Hemmelrath & Partner is to open an office in Stuttgart this summer giving the firm its 20th office worldwide.

The Stuttgart office gives the firm eight offices in Germany, completing its domestic coverage. It now has bases in every major city. Initially, the office will be staffed by partner Matthias Schueppen, who is relocating from Munich and a group of tax and audit partners who are defecting from the local office of a Big Five accountant.
