We Provide Comprehensive Employment Screening Locally and Nationwide

AZC Drug Testing is more than a drug and alcohol testing company. We are a full-service employment screening business that delivers peace of mind with our comprehensive compliance programs. When you choose to work with our knowledgeable compliance experts, you can rest assured that you or your employees will have all of the bases covered.

AZC Drug Testing and Oschmann: Better Together

AZC Drug Testing has seen a lot of growth over the past several decades.  Our most recent acquisitions in 2021 resulted in the addition of our 6 wholly-owned Arizona collections sites and rebranding to AZC Drug Testing.

Our company has been serving clients nationwide since 1996, when our Founder and President, Gary Oschmann, launched The Oschmann Organization.  Mr. Oschmann built the company working out of his one-bedroom apartment, beginning with just one client before moving to our first office in Tucson, AZ in 1997.  From these humble roots and the acquisition of several smaller companies, Oschmann Employee Screening Services grew to provide comprehensive drug test management and employment screening services to clients throughout the country.

We’ve Expanded Our Operations to Better Serve Our Customers

The company continued to grow over the years, adding a custom-built collection van to accommodate mobile testing services in 2006, and moving our headquarters to a larger, custom building one year later. In 2013, the company took a giant leap forward with the acquisition of Professional Air Charter Services. This move enabled Oschmann Employee Screening Services to significantly expand our DOT consortium programs, thereby providing a complete spectrum of compliance services to our clients.

In more recent years, Oschmann has expanded our local presence in Arizona with the acquisition of Reliable On-Site Substance Testing in Phoenix, along with additional mobile testing units and collection sites throughout the state. We continue to participate in nationwide collection site testing services. The company has also relocated its headquarters again, settling into a larger facility that reflects our considerable expansion and enables us to better serve the needs of our clients.

In 2021, Oschmann acquired America Drug Testing and AZ Clinical Services, LLC. These latest acquisitions led to the overall rebranding of Oschmann to AZC Drug Testing. Under the AZC Drug Testing brand, we continue to serve our customers at our local collection sites.
