TANG & COMPANY

About TANG & COMPANY

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,
