PJ's grandfather, Al Giacomini, started building homes back in 1958. Al earned an excellent reputation for the long lasting family homes he built. Al had a long and enterprising career as a builder. He was the first to establish the Giacomini name in the construction industry. Soon after Al established himself, his sons entered the business to work with their father. Tom, Al, Pete and Bob Giacomini followed in their father's footsteps and each benefited greatly under their father's tutlage. Today, each of the brothers have their own construction companies and they all have excellent reputations. Moreover, they all have ventured into real estate development. They have developed sucessful subdivisions, such as Cobblestone Estates, Country Meadows, and Chapel Hill.

PJ entered the business with his father. PJ started working for his father in high school. Upon graduating, he became the foreman for his father's construction company, well known for elite class home-building. They built homes in Panther Creek, Chapel Hill, Cobblestone Estates, Cider Mill, Country Meadows and many more.

Throughout PJ's experience with his father, he learned the industry and, in 1994, PJ opened his own construction company. Since that time, PJ has framed many of the elite class homes in this area and he has gained a reputation for being the best at what he does. Today, PJ and his family represent 6 Construction Companies serving Central Illinois with three generations of experience.
