A century of innovation

History

Project Milestones

For over a century, UMC has developed and redefined the skylines of the Pacific Northwest. From humble beginnings as a small heating and plumbing shop founded by the Granston's in the early 1900s, we have thrived through significant historical moments - the Great Depression, World War II, the Vietnam War, a recession in the ‘70s, the technology boom then bust of the ‘90s, and the economic downturn of 2008. Today, we’re stronger than ever. Our diverse team takes pride in creating exceptional building experiences and innovations that will define this region for the next 100 years.
