Professional Engineering Consultants

Professional Engineering Consultants (PEC) was founded more than half a century ago on the promise that we would apply scientific principles to make things work, and ultimately, create opportunities. Today, we are a family of more than 400 multi

discipline professionals, working across dozens of disciplines, serving all 50 states. From PEC’s locations in Kansas, Oklahoma, Missouri, and Colorado, our work takes us across the nation and around the world to design an increasing variety of projects. From the roads and bridges connecting them, the energy powering them, the hospitals healing them, and the schools teaching them, PEC strives to better the communities you lead and live in.
