Andrew brings deep industry knowledge, a strong understanding of our business, and a genuine commitment to Pennoni’s values. I am confident he will lead the firm forward with integrity and vision,” says DeLizza.
Andrew Pennoni, son of founder and Chairman of the Board Chuck Pennoni, brings extensive experience across engineering, construction, and inspection services. His background includes civil engineering, construction management, construction inspection, fabrication inspection, materials testing, surveying land development and public works infrastructure. Throughout his career, Andrew has been closely involved in project management, design, construction, quality assurance, contracts, and working with public agencies to help deliver complex infrastructure projects.
“I am grateful for the trust placed in me and deeply appreciative of Dave’s leadership and mentorship. Pennoni has a remarkable legacy built on technical excellence, strong relationships, and doing the right thing. As CEO, I look forward to building on that foundation, supporting our teams and continuing to serve our clients and communities with the same care and commitment that have defined this firm for 60 years,” said Andrew Pennoni.
As part of this leadership transition, Pennoni will also be announcing upcoming organizational updates within its Construction Services region, reflecting the firm’s continued growth and focus on aligning expertise with client needs. Additional details will be shared in the coming weeks.
