Pennoni through the Years

by David DeLizza, president and CEO


As we kick off Engineers Week 2022, we thank the engineers of yesterday and today whose hard work and dedication have made Pennoni the firm that we are. Our long-term success can be directly attributed to our engineers, supporting staff and their continued commitment to furthering the knowledge and technology of our practice.

Since our founding in 1966, we have grown from a one-person structural engineering practice to a multidiscipline consulting firm. While our focus is on building the future, it is appropriate to take a moment to honor our past.

Here is a brief history of Pennoni:

  • 1966 – C.R. “Chuck” Pennoni begins his one-person structural engineering practice in West Philadelphia
  • 1967 – The business entity changes from sole practitioner to business corporation and Leo Storniolo is hired at Pennoni Associates Inc. as the first full-time employee
