Why Us?

Our History and Purpose Define Who We Are And How We Serve


Our story started in 1977, as a single medical clinic in Long Beach, CA. that was to become CareOnSite Medical Services.

Since then, we have grown into more than just a medical provider. In 1998, ASAP Drug Solutions was begun as a response to our clients’ drug-testing needs; then came OSCA in 2003, representing our foray into the safety training arena. We have also expanded our presence in the US, with offices in Carson, Martinez and Houston.

In 2016, our parent company Tang & Company was established, bringing the three separate businesses in our family – CareOnSite, ASAP and OSCA – under the same umbrella. The move has allowed us to create synergies among the businesses as we integrate our products, services, marketing strategies and corporate infrastructure, providing for our clients a truly one-stop shop solution for worker health, safety and security.


Everyday, we strive to improve the business performance of our clients by helping them achieve their workplace health and safety goals. By doing this, we know our clients will have more resources to hire and innovate to keep communities across America growing, vibrant and more productive.


We partner with our clients to promote a safe and well-trained workforce. Our highly skilled team is committed to delivering excellence in innovative safety-training solutions customized to each client’s unique requirements.
