OSI provides commercial office furniture installation, relocation, decommissioning, and repair across the state of Arizona. Headquartered in Phoenix with a 60,000-square-foot warehouse, our crews handle everything from single-office installs to multi-floor corporate deployments — in the Valley and well beyond it. Dealers, project managers, and facility teams rely on us in Tucson, Flagstaff, Prescott, Yuma, and dozens of communities in between. We also regularly support projects in the Las Vegas area and parts of Southern California. If your project is in the Southwest, chances are we already work where you are.
