The tax consultant couple Evelyn and Hans Gantner laid the foundation for today’s partnership company in 1977.

They founded their small office in Griesheim under the name “Gantner & Gantner”, but it soon had to be expanded and enlarged.

In 1986, new office space was rented in Wilhelm-Leuschner-Straße 22. At this location, the law firm continued to develop very satisfactorily. From 1995 to 2004, Mr. and Mrs. Gantner maintained an office at their residence in Lichtenberg, but then returned to Griesheim.

In 2013, as part of the initiated company succession, Mrs. Evelyn Gantner transferred her share to her colleague Mike Lanfermann. The partnership company “Gantner – Lanfermann Partnerschaft mbB” was born – it grew strongly and with the transfer of Mr. Hans Gantner’s share in 2020 to colleague Sascha Junker, the succession was completed.

The rooms in Wilhelm-Leuschner-Straße were soon too small, so the new partners built a new modern office building in Wiesenstraße 9, which could be inaugurated in 2022.

Our new building

As the location of many years in Wilhelm-Leuschner-Straße 22 was getting on in years and also the necessary spatial capacities were no longer offered, we decided to build a modern office building in Wiesenstraße 9 in Griesheim. After the swift implementation of the new building project, we were able to move into the new premises in November 2022.

In the spirit of sustainability, the new office building meets the highest energy standards. A photovoltaic system was installed on the flat roof, which produces more electricity over the course of the year than we consume at our site. Heating is provided in an energy-efficient manner by a modern heat pump. With a view to the future, four charging points are available for charging electric cars.

Inside the office building, we have placed great emphasis on a homely atmosphere. The premises are bright and modern in design and are intended to facilitate pleasant and efficient working. The office equipment has been completely renewed and is designed to optimally meet the needs of our employees.
