About Missouri Cannabis Testing

Missouri Cannabis Testing, a Division of EKG Labs, was founded in 2013 by Jennifer Eagan, Allen Kesselring, and Katie Grayson. The founders have spent the majority of their careers working within contract research laboratories focused on combination product, medical device, and pharmaceutical development. A little over 7 years ago, the opportunity arose for Eagan, Kesselring, and Grayson to leverage their experience and history together to create a new business endeavor. Drawing on their collective 50+ years of experience working with DEA controlled substances (including CBD, THC, general cannabinoids and their metabolites), the team decided to utilize their knowledge in pharmaceutical science and passion for medical cannabis to form the medicinal marijuana division, MoCann Testing. Their mission is to help individuals across the state ensure they have access to safe medical marijuana through accurate sample testing and quality results.
