“Excitement is the feeling I get every Sunday about 2pm gearing up for the coming week at Johnston. It is very satisfying, and I am very fortunate to be a part of a team that serves as trusted consultants to our expanding client base. Growing up around the A/E business, in addition to being a third-generation engineer, may have something to do with it, but for as long as I can remember, I have wanted to do exactly what I am doing today.


What is most gratifying about Johnston is simply, our ability to provide effective solutions to our clients. It makes it even more rewarding when you can provide these solutions through the collaborative support of the talented individuals that make up our firm.Johnston is a successful practice with strong core values including commitment to our clients, employees and the built environment.”
