Cannabis Business Licensing and Regulatory Advice

  • Acted as regulatory consultant for Botannis Labs, a nationwide cannabis testing company, in its application for and acquisition of the first ever medical marijuana license issued in the state of Missouri. Botannis secured one of only ten testing facility licenses issued statewide in Missouri through one of the most competitive state application processes in the nation. The company obtained the top score out of all Missouri laboratory applicants. Amber received ISO certification by A2LA, a leading laboratory accreditation body, and her background in laboratory operations proved to be one of the differentiating factors that helped foster Botannis' winning application.
