U.S. HealthWorks was a prominent national operator of occupational healthcare centers, providing services such as injury and illness treatment, pre-employment screening, physical therapy, and wellness programs. Founded in 1995 to deliver quality care to employees and employers, it grew to a significant network of over 250 clinics and worksite locations across the United States. In February 2018, U.S. HealthWorks was acquired by Concentra, a subsidiary of Select Medical. This acquisition integrated U.S. HealthWorks' operations into Concentra, further expanding Concentra's footprint in the occupational health sector. While U.S. HealthWorks no longer operates as an independent entity, its legacy in workplace health continues through Concentra's comprehensive services, aiming to improve the health, safety, and productivity of America's workforce.
The Valencia headquarters served as the central administrative, operational, and strategic hub for U.S. HealthWorks' national network of occupational health clinics. It oversaw areas such as finance, human resources, IT, clinical operations, and business development.
The headquarters was situated in a contemporary office park, common for corporate entities in the Santa Clarita Valley. Specific unique architectural highlights were not widely publicized.
As a healthcare provider, the corporate culture at U.S. HealthWorks likely emphasized patient-centered care, operational efficiency, regulatory compliance, and a commitment to workplace safety. The environment would have been focused on supporting its numerous clinics and fostering growth in the competitive occupational health market.
This headquarters was significant as the command center for one of the largest occupational health providers in the U.S., directing services that impacted millions of employees and thousands of employers annually prior to its integration into Concentra.
U.S. HealthWorks operated exclusively within the United States. Following its acquisition by Concentra, which is also primarily U.S.-focused, its services and operational footprint remain concentrated in the USA. Concentra, as part of Select Medical Holdings Corporation, does not have a significant direct international brand presence for its occupational health centers, although Select Medical has some rehabilitation hospital joint ventures internationally.
