Colleen Wienhoff

For over 33 years Colleen has been doing federally-mandated and non-mandated drug and alcohol testing. A fortunate conversation she had as a nurse inspired Colleen to venture into the drug and alcohol testing industry and she founded Wienhoff Drug Testing in 1988. In 2006, Colleen decided to expand and purchased Bio-Med Testing in Salem, Oregon. Some additional services offered by her companies are DOT Consortium Management, Pre-Audits, background checks, drug and alcohol policies, trainings for both Reasonable Suspicion and Designated Employer Representatives.

Colleen has served on DATIA and SAPPA boards various years from 1995 to 2018. Volunteering is dear to Colleen’s heart as well, and has been involved with the National Prescription Drug Take-Back, Project Patch which mentors high-risk teens, partnering with Idaho Anti-Drug Coalition and doing medical missions in Eswatini South Africa every 2 years.

Colleen can be hard talking about the importance of her client’s compliance and how she loves to teach and help. “My passion is to teach them what I have learned.”
