Patient-Focused Marijuana Consulting

We are a Chicago, IL-based international marijuana consulting company. Quantum 9’s areas of expertise include permit acquisition, staff augmentation, and employee training. The primary objective is to provide expert marijuana consulting to help connect patients with the necessary resources while aiding investors, entrepreneurs, employees, and potential patients into the cannabis industry.

Michael Mayes is the Founder and Chief Executive Officer for Quantum 9, quoted regularly in the Marijuana Business Daily. Our CEO has assisted in project managing and funding some of the largest commercial cannabis consulting projects in the world. He helped raise $15M for an international venture for one project as a subject matter expert through Quantum 9’s investor services. Michael has been a cannabis investor since 2009 in Colorado’s first legal for-profit marijuana market and has spent years consulting and collaborating with countless consultants on the forefront of the marijuana industry. Working with the brightest minds and contributing to world-class organizations has been an incredibly enlightening and rewarding experience for Quantum 9.
