Caring about our employees is a goal, and we work with processes and procedures that allow the proper development of our activities within a safe framework and prevention. Both the health and safety of those who make Serza are part of the culture of our company. We train and raise awareness of the importance of safe work, with a healthy work management and a strong emphasis on prevention. This allows us to provide a solid environment where our employees can develop and perform their functions with our experience as a backup.


Caring for the environment is one of our highest priorities, analysing the impact that our activities can have on the planet, mitigating the risks with an orientation to reduce the use of non-renewable resources. This distinguishes us as an environmentally-responsible company.


Serza has certified procedures on vehicles that are operated by the company, guaranteeing safety at all times and a quick and efficient response for the provision of the service. We have high quality standards in road safety through process control and permanent staff training.
