NATIONAL MEDICAL GROUP

Education and Training > Language and Speech Services

Our story started in 1977 as a single medical clinic in Long Beach, CA. 40 years later, CareOnSite Medical Services is still physician-led, and has grown to hundreds of locations across the USA and 5 offices in: Long Beach, Torrance, Carson, and Martinez, California as well as Houston, Texas.

Along the way we’ve grown to become more than just a medical provider. In 1998, ASAP Drug Solutions was launched to support our clients’ drug-testing needs. Then in 2003, OSCA was founded to offer high-quality safety training to high-hazard industries.

The Tang & Company parent company brings these three businesses – CareOnSite, ASAP, and OSCA – under the same umbrella. This move has allowed us to integrate our products, services, and corporate infrastructure, providing a truly one-stop solution for worker health, safety, and security.
