Doping Control Officers (DCO)

“Class,” “professionalism,” “thorough,” and “communicative” are words that have been used by clients in describing our collection crews. They are responsible for the securing of fluid specimens (urine, blood, saliva) from athletes, in order to ensure fair play. Trust and respect is given to each athlete and client contact throughout the process, with a collaborative and regimented planning process for scheduling, selection, and sharing results. We value their important role in tactically and tactfully leading fluid-based drug testing procedures for sports organizations worldwide, within a variety of environments.

When your athletes’ well-being is at stake, you want to know that your organization’s information in secure, reliable hands. Time and time again, these men and women have shown that they are worthy of our trust, and yours.

We are always interested in expanding our collection network. If you are interested in becoming a DCO, please complete the DCO application by clicking on the button below.
