© [Translate to English:] Reso Partners AG

The acquisition of Reso Partners AG adds a range of building management consulting services to complement Drees & Sommer’s existing Swiss portfolio and represents another major step in the successful project management and consulting firm’s strategy of internationalisation. Reso Partners AG, formerly part of Reso Group AG, employs 30 staff at its offices in Zurich and Lausanne and is one of Switzerland’s foremost property consultants.

‘The takeover will help us to expand our market position in Switzerland and, more widely, in Europe. Reso Partners AG is a well-known company with a very strong reputation, an extensive portfolio and outstanding customer relations. The Lausanne office in particular will allow us to expand into French-speaking Switzerland,’ explains Steffen Szeidl of Drees & Sommer SE’s Executive Board. Reso Partners AG’s portfolio includes property and facility management consulting, property advisory, life cycle management and service management.

As a wholly-owned subsidiary of Drees & Sommer Schweiz AG, Reso Partners AG now forms part of Drees & Sommer SE. Following the change of ownership, the Reso name will now appear together with the phrase ‘Part of Drees & Sommer’. Roger Krieg, Christoph Heer and Ernst Roth of the current management team will retain portfolio responsibility. Further information about the company can be found at

The owner-run firm Reso Group AG and its remaining subsidiaries, Offconsult AG, Office LAB AG and datamind advisory AG, will continue to operate independently of Drees & Sommer.
