No Challenge Too Big

Over 20 years ago, two hard-working brothers started Loenbro with a beat-up pickup truck, some welding equipment and an ambitious goal. Today, we are a national company that designs and constructs complicated projects and provides essential services to many industries – from mining and power to energy and manufacturing.

Our Values Guide Us

While our company has changed dramatically in the last 20 years, our beliefs have not. We’re still the same down-to-earth, straight-shooting and skilled people who always put in a good, hard day’s work. We live by our code of conduct – the Loenbro values that define who we are.
