When adult-use sale of marijuana became legal in Illinois at the start of 2020, Blume led Chicago-based Green Thumb Industries’ transition of three retail locations from medical cannabis sales to include adult-use sales. He also led the opening of three additional stores in the state as well as the transition of two other locations. Illinois deemed cannabis essential during COVID-19, and Brendan led the retail team through new safety protocols while continuing to serve patients and customers. This included improving Green Thumb’s digital retail experience; developing online payment systems in certain states; establishing a customer support center; and developing the company’s delivery and curbside pickup capabilities. Despite all of the challenges of 2020, Blume also helped open 11 new retail locations during the year.
