Carmine started working at an early age in the construction business owned by his father Carmine Serafino, one of the very first in Crotone.
At the age of 19, Carmine moved from Calabria to Milan and began working as a yard foreman for several major construction companies of the area, further expanding and refining his professional expertise and founding in the 1980s Edil Carbone, later to become Edil CM, which worked alongside Italcantieri -one among several major partnerships- in the construction of Milano3.
