Valencia-based U.S. HealthWorks, a national operator of occupational health care centers, announced the acquisition of the Cupertino Medical Group bringing the number of medical centers it operates to 66 in California and 172 nationwide.

Terms of the transaction were not disclosed.

The facility will continue to offer a wide range of urgent care and occupational health care 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.

“We are pleased to be a part of a strong and growing organization like U.S. HealthWorks,” said Dr. Yung Chen, owner and medical director of the Cupertino Medical Group. “It’s exciting for our medical staff to join a company that offers many innovative approaches during these changing times in health care coverage.”

U.S. HealthWorks has 21 centers in Northern California, including centers in San Jose, Santa Clara, Sunnyvale and Milpitas.

“We’re thrilled to expand our coverage in the San Jose region and to welcome the staff of Cupertino Medical Group to U.S. HealthWorks,” Therese Hernandez, senior vice president of operations for U.S. HealthWorks in California said in a prepared statement. “This new location offers our existing clients and patients another excellent choice for occupational health and urgent care services.”

U.S. HealthWorks has been on an expansion kick, acquiring more than a dozen clinic operators in the past year as part of its aggressive growth strategy. CEO Dan Crowley said late last year that his goal is to make U.S. HealthWorks the nation’s largest operator of outpatient occupational health centers. Financing of $205 million from GE Capital has helped the company fulfill its goal. U.S. HealthWorks now claims to be the largest independent operator serving 11,000 patients every day in 15 states with the help of more than 2,700 employees.
