What Our Team Says

“I like working in airports and aviation because of the access and recreational opportunities it provides to communities.”

"My favorite story from my time at Interstate Engineering is going out to survey a river during the middle of winter and breaking ice with a spud bar to get into the river channel."

"Endless stories, but the ones that stand out have a collective theme: community. There are many examples of how individuals have made clients and team members feel part of the company or their families. This is not one person but a running theme and core value of the company. This is a company that is always building community."

"As I am in the field most of the time, things that I find interesting are two yellow rubber ducks in a drainage ditch, watching the neighbors argue over a property line, working with and watching staff develop skills that surpass myself."

"I hope to make a positive impact in not only the community I grew up in, but in the surrounding area as well. Engineering isn't necessarily local in Eastern Montana, and it's a privilege to be a part of a team that is."

"I hope to be able to improve the communities we live and work in by helping to complete projects that benefit those communities."

"I hope that through proper long-term planning, I could reduce potential future negative consequences for the client, environment, etc."
