Making History

Partners for What's Possible

We approach the start of every project as the beginning of a collaboration because we understand the value of partnership. As a multidisciplinary firm, Pennoni has the ability to approach engineering challenges from a wider spectrum of angles than most. From land development to energy management, our expertise runs deep and our passion for problem-solving runs even deeper.

Longevity meets flexibility

Throughout five decades, our commitment to elevating the impact of our outcomes through personalized service has been steadfast. We have the experience to anticipate roadblocks and the insight to understand how to move past them. We have the flexibility to be innovative in our approach with the integrity to get things right.

What Clients Say

Our hands-on approach and forward-thinking manner has created problems with engineers in the past. However, you and your team have embraced our methods, and we have developed a good working relationship.”

– New Castle Municipal Services Commission

What Clients Say

“First of all, I want to thank Pennoni. You guys are the best. Without you, I don’t know where we would have been on this project. I know safety is the primary concern of all of us. That was our number one concern as a city.”

–  James Parent, Vice Mayor of Millville, NJ

What Clients Say

“From the initial pre-planning meeting through project completion, the Pennoni engineers, designers and project managers met every expectation and insured a successful result.”

–  David J. Hemple, Century Savings Bank CEO

What Clients Say

“Pennoni was able to help guide our Community through a five-year process which saw a failed concrete bridge which was traveled by over 600 vehicles a day, transformed into brand new construction which is designed to today’s standards. Without Pennoni’s ability to manage a project which required ongoing communications between a private community and various State and County regulatory and funding entities, the project might never have gotten off the ground, and might have resulted in a public safety disaster and a collapse in the value of our homes and property.”

– Rob Hoffman, WCA President
