About me

Steuerberater ZiemannSince 1999 I have been engaged on a professional level with tax consulting. As it was, I have learnt the matter from scratch. After serving an apprenticeship as paralegal tax consultant, I attended the Berlin School of Revenue Authorities which I accomplished with the degree of Public Finances. Thereafter, I took up working with PricewaterhouseCoopers AG WPG as associate, mainly covering real estate tax compliance as well as counseling various transactions.

In 2012 I attained the title of a certified Tax Adviser, in the Federal State of Berlin. In April 2012 I have joined the tax consultancy firm of Christoph Obert which I have taken over in April 2013.
