Additional Information

Bethany has worked in the forensic science industry since 2005. Early in her career, she had the opportunity to open a new regional forensic science laboratory in southeastern NC. She began an 11 year journey and gained a career’s worth of experience as a laboratory director, quality assurance manager, laboratory scientist, grant writer and manager. She is a trained lead and technical assessor for ISO 17025:2017. She is extremely passionate about truth and justice and has learned that the legal system is not always fair. She has a strong desire to see people held accountable to high standards for their work when it affects the lives and freedom of others. She maintains high integrity in her work and interactions. She became very interested in the growing cannabis industry while working in the forensics world. She believes the cannabis testing industry has a lot to learn from the forensic science industry about how to self-regulate in a world where you are not regulated. She believes in the benefits of cannabis to individuals and the economy and strives to be a source of knowledge to ensure that products on the market are legal, high-quality, stringently tested, and safe.
