Our tax and audit firm was established in 1980 by our founder Dr. Michael Hagemann. Many of our clients have been placing trust in us since these days. Today’s partners, Michael Kettern and Mathias Lindemann, joined the company in 1997 and 1999 and acquired it from the founder in 2009 as experienced consultants. Until the end of 2017, our firm used our founder’s name as Dr. Michael Hagemann GmbH & Co. KG.
In 2018 we change our name: We are now Kettern Lindemann & Kollegen.
Your advisers and contact persons don’t change: The partners are the same, the associate tax advisers and auditors and the other professionals will be the same. Our address will also remain unchanged.
The old emails addresses @dr-hagemann.de will still be available, but please amend your address books to our new addresses @kl-kollegen.de.
