About Us
About Alberta Occupational Drug and Alcohol Testing Services
As trusted leaders in the Alberta Occupational drug and alcohol testing services industry, the Alberta Occupational Testing Services team brings over 40 years of valuable knowledge, experience, and passion to the business.
When 26-year RCMP veteran Gerry Tetzloff founded the company in 1980 as a testing agent under Maxxam Analytics Inc, he already had over 20 years of drug and alcohol testing under his belt. Gerry’s unique skill set, coupled with a passion for customer care, ultimately gave him the tools and resources to branch off independently with Alberta Occupational Testing Ltd in 2010.
Since its humble beginning, Alberta Occupational Testing Ltd. has acquired over 100 direct clients and a handful of third-party administrators who request drug testing services on a regular basis.
