The Reilly Engineering tradition began in 1930 with John J. Reilly, a civil engineer and surveyor. Over the next four decades Reilly Associates established itself as the premier municipal engineering firm in northeastern Pennsylvania. John Reilly directed the design of new municipal buildings, fire stations, roadways and sewer systems for public clients. In an era when engineering tended to be practiced on a local scale, John Reilly managed the design of projects from Susquehanna County to Columbia County. John Reilly brought good paying, skilled jobs to Pennsylvania.
In 1960, Thomas J. Reilly, graduated form Lehigh University and embarked on an engineering career that has seen many advances in infrastructure, technology and design. In 1960, engineers were still using slide rules for computations, all drawings were done by hand, and surveying involved non electronic transits.
In 1965, Thomas J. Reilly, succeeded his father as president of Reilly Associates. Over the next thirty-six years, Thomas Reilly has expanded the company’s geographic service area and has expanded its professional line of services. He added environmental services to its traditional structural, civil, transportation, water and wastewater areas of practice.
