Meet Marsha Quinlan, SAP

Credentials & qualifications

Under 49 CFR §40.281, only certain credentialed clinicians who complete DOT-specific qualification training, pass a knowledge exam, and meet ongoing continuing-education requirements may serve as a Substance Abuse Professional. Here's what that looks like for Marsha Quinlan:

• Licensed clinical credential meeting 49 CFR §40.281(a) qualification
• Completion of DOT-required SAP qualification training under §40.281(c)
• Passed DOT-required SAP qualification examination
• Ongoing continuing education under §40.281(d) — 12 CEUs every 3 years

Experience

• Return-to-duty SAP evaluations for FMCSA, FAA, FTA, FRA, and PHMSA-covered employees
• FMCSA Drug & Alcohol Clearinghouse reporting for CDL drivers
• Coordination with employer DERs and Consortium / Third-Party Administrators (C/TPAs)
• Confidential clinical assessment for safety-sensitive workers across Pennsylvania

Why credentials matter

If your SAP evaluation is performed by someone who does not meet the §40.281 qualification standards, the entire process is invalid — and you cannot legally return to safety-sensitive duty. Asking about credentials is fair, expected, and encouraged.
