Seattle dominates Washington’s healthcare market in a way that few cities dominate their states, and the volume of allied travel jobs available reflects the metro’s size, density, and clinical complexity. Spokane serves as the primary hub for eastern Washington, a region that is geographically and culturally distinct and relies on allied travelers to maintain specialty services across a large rural footprint. The Cascades effectively split the state into two operating environments, giving clinicians the opportunity to choose the setting that fits their lifestyle. Western Washington is wet and mild year-round; eastern Washington has colder winters and dry summers. Cost of living in Seattle has risen, while Spokane remains more affordable. Washington’s breadth of settings keeps allied assignments consistently active.
