Quick, accurate results, and excellent customer service.
As the Human Resources Manager for Del Monte Foods’ Modesto plant, I have had the pleasure of working with Preferred Alliance for our seasonal drug testing needs since 1998. Preferred Alliance offers quality customer service and quick and accurate results. In our industry, we place high demands on our testing providers for flexible scheduling, quick turnaround, and competitive pricing. Preferred Alliance has consistently exceeded our expectations.

Human Resources Manager
We're confident in our compliance thanks to Preferred Alliance.
We started with Preferred Alliance when the DOT first began enforcing the random drug and alcohol rule. I have never worried about recordkeeping or testing matters because of their management of these highly sensitive, complex tasks. With Preferred Alliance as our TPA, we’re confident our compliance record will stay intact.

Professional, empathetic, and immediately responsive.
Merced County Schools Insurance Group has contracted with Preferred Alliance since DOT-required compliance began for our Member District’s commercially licensed drivers. The program has been seamless and, without exception, perfectly compliant and trouble free.
The on-site testing option makes all the difference. Employees appreciate the convenient, consistent and respectful handling of the sampling process. Equally important is that the school districts are not inconvenienced. Many drivers also work in other capacities after driving their morning routes. If the testing were at a remote facility, many employers would lose service and productivity. With on-site testing, there’s no delay.
Preferred Alliance’s reporting and documentation services have resulted in years of successful audits by CHP. We would never consider changing to a different provider—Preferred Alliance is truly the best partner in assisting our Member Districts.Terri Prichard
