Under the new name we assure you of our full commitment to you and your interests and look forward to future cooperation or the continuation of our previous collaboration with you. 


Information on precautionary measures regarding SARS-CoV-2 / Covid-19

Our office remains fully functional. However, we have decided to reduce our presence in the office spaces for the time being due to our duty of care for all of us, our families and the public. These measures minimize contact in person due to the general SARS-CoV-2/Covid-19 situation.

This does not affect the processing of mandates, as our home office workstations enable us to maintain the firm's activities without restriction.
