Doping Control Officers

USADA’s doping control officers (DCOs) are hired, trained, and employed directly by the U.S. Anti-Doping Agency, not a third party agency, in an effort to ensure the highest level of quality control and effectiveness in upholding the World Anti-Doping Code and accompanying International Standards as they relate to sample collection. USADA’s DCOs are situated throughout the country and have significant experience collecting samples both in and out-of-competition setting and at events.
