About Us


It all started 34 years ago behind an old wooden desk in a two-room apartment with founder Jon D’Allessandro, one employee and a 580E Case loader backhoe. Back then, Jon had a vision of what he wanted his company to be – a team of highly-skilled construction professionals who were reliable, competent, experienced and who would do whatever it took to get the job done right.

Since then, that vision has been realized many times over. D’Allessandro Corp has become a respected leader in the construction industry through the expertise and efforts of a loyal, dedicated team. D’Allessandro Corp’s attention to detail and focus on customer satisfaction has brought exponential growth, many industry awards and has earned the utmost respect from clients and peers alike.

“Our corporate responsibility is to contribute to the improvement of our industry and the communities in which we work.”
