As a Certified MillerKnoll Dealer and DIRTT partner, BSI serves corporate, healthcare, education, government, and nonprofit clients on projects ranging from single-room refreshes to full HQ relocations and new construction. BSI has a dedicated sales representative based in Sheboygan County, offering local, integrated expertise without the coordination headache of managing multiple vendors.
