Loenbro Founded in 1998 by Paul and Jon Leach, Loenbro began as a small team of welders focusing predominantly on refinery projects throughout Montana.

As our reputation for quality work expanded, so did our company, allowing us to explore the many new and emerging areas within our industry. We have also continued to invest our time and resources in the best tools, the latest technologies, and training our team to ensure that they consistently deliver the best products and services available anywhere. Today, Loenbro offers various services, inclu

ding plant maintenance, phased array inspection, HDPE fusion, exotic materials welding, heat treating, pipeline construction, industrial insulation, and heavy industrial construction. Our team now includes more than 1,300 of the best welders and industry professionals available anywhere. Together, we continue to look for new opportunities to better meet our client's changing needs.

Members of Loenbro's West Region teams were excited to attend TESSA's annual Pasta in the Park fundraiser in Colorado Springs, Colorado on August 15th! The event brought the community together to support TESSA's mission of providing safety, support, and resources for individuals and families impacted by domestic violence, sexual assault, and the related challenges.

We're proud to support organizations like TESSA that help strengthen our communities and protect the most vulnerable. Thanks to everyone who attended and represented Loenbro at this amazing event!

On National 811 Day, we recognize the importance of protecting the underground infrastructure that powers our communities. Taking the time to call 8-1-1 to locate buried utilities before excavation helps prevent damage, protects the public, and keeps projects moving safely and efficiently.

At Loenbro, we believe the safest work is built on preparation. Because protecting what lies beneath helps safeguard everything above it.
