From humble beginnings to industry leadership

Our story

From pre-employment drug testing to industry leadership, Preferred Alliance has grown through innovation and expertise, providing businesses with reliable drug and alcohol testing services for over 40 years.

The origins of Preferred Alliance

In 1989, Preferred Alliance was established as a specialized arm of Health Services & Benefits Administration (HS&BA) to offer pre-employment drug testing. Starting with major clients like Tri-Valley Growers and Del Monte USA, our services quickly grew in response to the introduction of stringent DOT regulations in the 1990s.

Our growth and expansion

Over the last 4 decades, Preferred Alliance has administered more than 1 million tests and has worked with over 5,000 clients. We’ve become a leader in third-party administration (TPA) for drug and alcohol testing, offering comprehensive DOT and non-DOT program administration and compliance support across various industries.
