DEA Compliance Expert

Former DEA Special Agent in Charge

Dennis A. Wichern

We are a dedicated group of former federal agents who have extensive compliance experience in DEA and state criminal, civil, and administrative actions relating to a wide variety of medical professions and healthcare organizations.  

Led by managing partner Dennis Wichern, a former DEA Special Agent with over 30 years of public service, PDC specializes in compliance consulting services through its office and practice reviews in addition to its highly specialized training programs.

We are experts in the requirements, nuances and interpretations of the Code of Federal Regulations and its applications to the ever-changing practice of medicine - especially in the areas of pain and opioid treatment, SAMHSA MAT and OTP regulations, pharmacy and ASC operations, and drug researcher protocols.  We are experts at the development and implementation of DEA corrective action plans.

The draft 2022 CDC opioid prescribing guidelines are a prime example of the ever-changing government policies on medical care as it relates to pain.


From our “first of its kind” 100 + audit checklists to our cutting edge, field-proven training programs, PDC gives providers and healthcare organizations peace of mind compliance driven solutions.
