Last April 27 was 51 years since we started this exciting journey that has led us to become what we know today as the Certis Group. We want to express our sincerest gratitude to all the people who have accompanied us on this journey. Without their collaboration it would have been impossible to move forward along this path. To celebrate this achievement, we present a video where you can see some of the work we have done over the course of these 51 years. It is an opportunity to reflect on our trajectory and the positive impact we have had throughout all this time. We hope you enjoy it as much as we did making it!
