Our History


Corporate History

PEC started with less than 30 people in 1965. Today, our staff of more than 400 holds professional engineering licenses in all 50 states. Our work takes us across the nation and around the world to design an increasing variety of projects from highways to hospitals — water towers to wind turbines — stadiums to sidewalks — and everything in between.

THANK YOU for being a part of our journey.
