Elektro Stoll GmbH is a family company, owned and managed by the second generation. Since 1992 the firm has been led by Markus Stoll.

The strength of the company lies in the synergy between the companies Elektro Stoll and Frey Ingenieur Gesellschaft. The interaction between the different divisions and departments and the efficient organisation which is consistent throughout the enterprise means that consistent and harmonised technology know-how is available to customers.

In 2005 a branch was established in Switzerland, and since 2006 the company has also been represented in Changchun, China.
