U.S. HealthWorks, the Valencia-based operator of occupational healthcare and urgent care medical centers, has acquired the Santa Rosa Walk-In Medical Center Inc. in Camarillo.

The acquisition brings the total number of U.S. HealthWorks centers to 66 in California, making it the largest providers of occupational health care in the state. The company provides urgent care services, along with work-related injury care, helping employers control costs through the management of claims and lost work time. HealthWorks also specializes in early return-to-work, injury prevention and wellness programs.

The company has been on an acquisition drive, buying 20 to 25 clinics across the country in the last two years, most of them small standalone operations. It now has 154 centers and worksites across 14 states, 2,000 employees and 350 affiliated physicians.

“It’s growth within our local communities that continues to build the loyal and trusting relationships which U.S. HealthWorks has proudly formed with both employers and patients,” Therese Hernandez, senior vice president and general manager of the California operations, said in a statement about the Santa Rosa acquisition.

The Camarillo facility will offer occupational medicine services, including diagnosis and treatment for injury and illness, preventive services, pre-employment and post-offer exams and screening, and return-to-work rehabilitative care. Terms of the transaction were not disclosed.

“We're very pleased to join U.S. HealthWorks,” said Dr. Walter Dugger, who will remain as the center’s medical director. “Our team of physicians and staff are looking forward to providing the same great medical service that we've established for many years.”
