The foundation for sdh was laid in 1995 by Markus Stender, then a one-man law firm at the location of the present office in Vienna. Over the last few decades the firm, , has been continuously and successfully expanded and by training young colleagues (most of whom are now members of the Vienna office) we have managed to establish a law firm with various specialisations.

Apart from being members of the European Lawyers Group network, the lawyers of sdh Rechtsanwälte have successfully established numerous contacts with partner law firms in Austria and abroad, in particular in Eastern Europe and in the Arab Region. Thus, we are able to advise clients in all fields of the law and in all countries of the EU, Eastern Europe, Russia and in the Arab countries, and to provide local support.

The working languages of the law firm are German, Spanish, English, Russian and Greek. Besides Vienna as the starting point and point of contact for a number of legal networks the opening of the office in Madrid (Spain) in 2015 constituted a further step towards globalisation.
