Covid-19 (Corona Virus) client information

To all customers and partners,

DDM Groupe and Groupe CHG respect all the measures deployed by our governments to slow the spread of COVID-19 and thus protect the health of all. Of course, the offices are closed, but the staff continue their work with the same rigor and efficiency, only the methods have been adapted. IT infrastructures allow employees to work remotely and offer you the services you are used to.

You can reach our team members by email, phone or videoconference. If you must send us documents by courier, we ask that you contact the designated project manager to plan a delivery agreement.

DDM Groupe and Groupe CHG wish to contribute to the efforts of the public administration in its fight against COVID-19. We thank you in advance for your cooperation and understanding.
