"I absolutely love working with Oregon Onsite Drug Testing!  They have the customer service feel of a family owned company, but the capacity to serve large clients which is a rare combination.  Whether it's reacting to an emergency or scheduling large scale collections, OODT has never let me down!"

-Nathan Taylor, Kerr Contactors

"Oregon Onsite Drug Testing has been amazing to work with over the past eight years.  They have been flexible and more than accommodating to fit our ever changing schedule.  The personable staff is always on time. prepared, knowledgable and above all professional.  Results are accurate, immediate and confidential.  If a drug free workplace is your goal, OODT is the company to call."

-Jim Kusyk, Sherwood School District

"Oregon Onsite Drug Testing is our go-to team for drug screen collections whether we’ve set up a long term onsite collections facility, need an emergency collection at the hospital or to test an entire job site at once. 

They have handled surprise random testing of over 1000 workers in one day for Hoffman, and have accommodated us holding a next day site-wide random test with very little lead time to prepare.

The staff are knowledgeable, have great rapport with the workers, get the paperwork and collections done correctly the first time and are very flexible."
