I am a PhD-level forensic and clinical toxicologist with over a decade of experience advising organizations, attorneys, and courts on complex toxicological, pharmacological, and regulatory matters. I served as the toxicologist for the federal courts drug testing contract for 3 years. In that role I testified at federal revocation hearings over 20 times concerning drug testing and wrote hundreds of formal letters of data interpretation for the courts. I also corresponded with attorneys and probation when the drug testing outcome may have been due to exposure or medication or diet. I have a National Registry of Certified Chemists board certification as a Toxicological Chemist, a MS and a PhD, and many years of experience directly operating laboratories.
