Dr. Gans Eichler Chemieberatung has been specializing in chemical compliance since January 1, 2010. Initially launched as a freelance endeavor by Dr. rer. nat. Timo Gans-Eichler, it steadily expanded, leading to the establishment of a GmbH (limited liability company) in 2015.

In 2022, a significant portion of the company shares was acquired by asseso AG, resulting in Dr. rer. nat. Timo Gans-Eichler stepping down from the position of managing director. He continues to serve as a consultant and can be reached at +49 (170) 2450126.
