Our friend and colleague Joaquín Montón has left us. He was a loved teacher by his students, a rigorous, methodical and irreplaceable professional and big expert in diagnosis and rehabilitation of wooden structures and other applications in our buildings. Above all else, he was a great person. We will miss your smile and your invaluable company. Always ready to help and support in difficult moments, always a protagonist in moments of joy, always attentive to everyone around him showing his most human side. In Catalonia, Spain, Mediterranean and all over the world, we have lost a great professional and an excellent teacher!
