About Us

Meet Todd Rowell, PE, Principal

Graduated 1984, Washington State - BS/Civil Engineering, Professional Engineer - Oregon and Washington


Todd says, “Growing up with Payton was fascinating. He could work for hours when he was doing numbers, but we were just as likely to go out and survey a site or chat with owners on their land, and I would hold the survey sticks or listen to him talk to guys with hammers and bulldozers."


When people tell me “you sound just like your dad”, I take it as a high compliment. What it means to me is that I have incorporated Dad’s love of people with his love of building and creating.


Todd enjoys finding a solution to a problem that exists in several domains — what people want, what the engineering requires, and what is practical and efficient to build.


He learned the details in school, but learned the craft from the best engineer he's ever known - Payton Rowell. Todd has brought those fundamentals into the present, and creates using new technology. He is proud of having built a team of young engineers who will take his philosophy even further into the future.
