Brothers with a vision

The values that make Loenbro what it is today were instilled in brothers Paul and Jon Leach as they grew up on a farm in Sun River, Montana.

From an early age, they had an affinity for all things mechanical. As kids, they learned the basics of welding and the value of hard work.

After younger brother Jon graduated from high school in 1998, the two went to welding school in Cleveland, Ohio, then returned home, started their careers and founded the company now known as Loenbro.

An attitude for success

“Growing up on a farm, you don’t ask ‘why’, you just figure out how to get it done.”
– Jon Leach, Loenbro co-founder

A company takes off

After returning home from welding school, the Leach brothers signed on for what they believed would be a two-week project at a local refinery in Great Falls.

Their first project rolled into another, then another as refinery supervisors, impressed with the brothers’ skills, work ethic and integrity, awarded them a wide variety of jobs.

Paul and Jon then hired others to help them, and their company was born.

Putting skills to work

Eager to get to work after boosting their welding skills at a school in Ohio, Jon and Paul bought a $750 Ford pickup, put two welding machines in the bed and began their welding career at a refinery in Great Falls.

Watch an early version of how Loenbro got started.

What’s in a name?

On the refinery job site, Spanish-speaking workers referred to Paul as “Lo,” short for “Pablo.” And younger Jon was simply called “Bro,” for “brother.” The combined nickname of “Lo and Bro” stuck.

So when the brothers incorporated their company in 2001, they didn’t have to brainstorm for long about a name. Lo-N-Bro was the obvious choice. The name was updated to Loenbro in 2011.
