Sirius has been building Western Montana since 1979.
Over the decades, we’ve experienced a steady and manageable rate of growth throughout our local building industry. Building
numerous landmark projects in Missoula and its surrounding areas, we’ve excelled in the Education, Government, Medical, Multi-Family and Retail industries.
Our Custom Interiors and Historical Renovation work is second to none, and we are the only General Contractor in western Montana with
the in-house capability to fabricate and erect ground to mid-rise steel structures. We are a company
that prides ourselves on self-performance, staffed with experience tradesmen with the experience and
know-how to perform work in all commercial building divisions. Our management staff brings over 100
years of collective experience in the industry, dedicated to a corporate culture where “on-time and in-
budget” is more a part of who we are and what we routinely do, rather than a goal we're constantly
chasing.
