Let us tell you a story.
A family story
full of unforgettable moments, hard work, and joy. It all began with the person, who has been the pillar of our company for years: its founder Domenico. He was not just an employer, but also a father, a grandfather, and a friend for all of us. Dad was an old-fashioned man of humble origins. He started working when he was five years old. At twenty-two, he was already a parent and emigrated to France. He loved engines and the sea. For him, a promise was a promise. The given word was worth more than a hundred contracts. Even now, people who knew him remind us of what great man he was: determined, honest, and fair. He was always very active in social fields, and he taught us the meaning of generosity. Domenico created L.M. Monticelli (the “workshop” as he liked to call it) with us, his children. This company has been helping hundreds of families in the Marche region for years.
Tireless, stubborn, with an iron will. He lived as a lion to the very end. He left an enormous gap in our lives, which can never be filled. But he taught us how to move forward.

SAFETY AT WORK
Education, information sharing, and training are the tools with which our company ensures a safe and healthy environment, in compliance with art. 37, paragraph 2 of Italian legislative decree no. 81 dated 9/04/2008 and subsequent State-Regions-Autonomous Provinces agreements dated 21/12/2011 and 25/07/2012.
Upon every update, we issue the Risk Assessment Document (RAD), which certifies all the preventive and protective measures we have taken to improve the level of safety, including the continuous research and improvement of the PPE provided to our employees. A specific department takes care of system engineering and repairs, paying special attention to system-managed maintenance. We pay the same attention to possible interference between our activity and that of any external companies by sharing information and issuing the operating safety plan (OSP) and single document on the assessment of risk from interference. The company also provides information and a protection kit to our clients who want to visit our production site.
