About CertifiedSAP
We connect DOT employees and employers with qualified Substance Abuse Professionals — and we train the next generation of SAPs.
Our mission
The DOT return-to-duty process is high-stakes for everyone involved. CertifiedSAP exists to make finding a qualified SAP simple, transparent, and fast — and to give new SAPs a clear, modern path to certification.
Our standards
Every SAP listed in our directory meets the qualification requirements of 49 CFR Part 40.281, holds an active license or certification, and maintains the 12 continuing-education hours required every three years.
Built by industry veterans
CertifiedSAP was founded by clinicians, compliance officers, and engineers who together have spent decades in the DOT testing space.
