After graduating from high school and training as a tax clerk in Wilhelmshaven, he went on to study at the University of Applied Sciences in Cologne. He worked for an international auditing firm for a good seven years, during which time he also passed the examination to become a tax consultant.

In 2008, Mr Arnold joined Zacharias & Demmer. After successfully passing the auditor’s examination, he has been a partner and shareholder at Zacharias & Demmer since 2010. His main activities include auditing annual financial statements and advising medium-sized companies and their shareholders on tax issues. As a father of two children, he is not only very active in sports as a triathlete, he also passively supports 1. FC Köln whenever his time allows. Cologne Carnival is also close to his heart. For years, he has been involved here on a voluntary basis in the promotion of customs.
