What Our Team Is Saying

Working alongside the wonderful people that work for Mortenson hands down changed my life. They’re real people, and it’s a total family. I love helping others, and the unity and family bond in the field and with Mortenson as a company makes me grateful for working my way to where I’m at right now.
One of the determining factors when I came to Mortenson was seeing the wall in the office where it has everyone’s anniversary of 25 years, 30 years, 40 years with the company. Nobody works for a company that long if they don’t love what they do, and not one of those people is doing the exact same things that they were hired to do when they got here.
For all the hard work, my family and I enjoy the vacation time offered and many Mortenson-sponsored activities. Another rewarding result is that my family and I can visit the buildings that I have been a part of constructing for years after they are complete.
