In a sign of the growing professionalization of the medical cannabis industry, Mark Rhoades and Ali Kashani, the owners of the Berkeley development company Citycentric Investments, have teamed up with Debby Goldsberry, a founder of the Berkeley Patients Group, to open a number of medical marijuana facilities around the East Bay. Goldsberry, Rhoades, and Kashani represent a new breed of medical marijuana entrepreneurs: people expert in land use policy, non-profit work, and running cannabis collectives. It’s a set of services that is growing in demand as more states adopt medical marijuana laws and as more people try to navigate the byzantine laws permitting medical marijuana in California.
