Dear customer and business partner,
we wish you and your team are well and safe, particularly during this season severely challenged by the widespread new outbreak of COVID-19.

This message is to provide an update on Testori Group status of activities, in the frame of the increasing measures enforced by different Countries to tackle the sanitary emergency.

At the moment, the restrictions and rules in place in the territories relevant to Testori’s presence are not affecting any of our sites in the Group.

Thanks to the resolute efforts and the rigorous safety protocols we have been proactively putting in place as from the beginning of the year, our facilities, as well as our commercial network, keep on being 100% operational. All our sites are working at full capacity and our manufacturing activities, logistics and support are regularly proceeding to guarantee the supply of products and services to our clients, directly or through our net of subsidiaries and distributors.

During this challenging time, in fact, Testori’s focus remains on creating the best possible conditions to continue supporting our customers and maintaining the high service level you expect from us, while ensuring the health and safety of all those who interact with our facilities, of our employees and of the local communities in which we operate. We have successfully worked to avoid disruptions caused by COVID-19, while at the same time acting responsibly to prevent further spread of the virus.

Businesswise, we’re facing Covid as a driver to implement new resources and start innovative initiatives, thus turning this undesirable situation into a chance for improvement. Unfortunately, the travelling restrictions widely enforced are severely hindering the possibility for our representatives to pay you a visit; nevertheless, we’ve adopted all the state-of-the-art communication and remote working systems that technology offers today, to keep staying in close contact with you. We are, at all level, trained and committed to effectively serving your account: we are, as always, here to assist you on planned and new projects.

We stay tuned on any possible change of the pandemic general scenario and we will keep you informed accordingly within the shortest possible time.
Stay safe and thank you for your trust during this situation.
