OUR TEAM
Rooted in Craft Since 1952
Founded in 1952, Millwork of Idaho began and eventually became a third-generation shop in St. Anthony.
In 2000, Zachary Petterson launched his artisan furniture and millwork collection.
In 2020, Zac acquired Millwork of Idaho. Reimagining the factory, he retooled as Timber Hardwood Flooring & Millwork, and continued his journey producing high end custom wood flooring and millwork projects for architectural and interior design firms, as well as custom home builders.
