More Than the Sum of its Parts

SIEMER + PARTNER provides financial auditing, tax consulting and business consulting for companies and private customers.

Our company was established in Bremen in the 1990’s to provide financial auditing and tax consulting. As we gained more insight into the business and better understanding of our customers’ needs, we soon started providing additional services in the field of business and legal consulting.

It goes without saying that our strengths are reflected in the accurate processing of financial audits and our commitment to all services involved in tax and business consulting. Our interdisciplinary approach also allows us to offer an extensive and precise analysis of the entire economic situation in which a firm operates. This analysis has proven to be of great value to many of our clients.

We ensure the high quality of our work by maintaining a multifaceted team and by providing regular training for our 80 employees.
