It’s been nearly a year since Colorado made recreational marijuana legal, and since then, pot has become a billion-dollar business in the state. And some growers have made it a mission to make it legitimate and mainstream.

“Change the face,” says pot entrepreneur Brooke Gehring. “But really, not to be the stereotype of what they think is stoner culture, but to realize they are true business people that are operating these companies.”

Gehring, smartly dressed in a business suit carrying an iPad and briefcase, runs two businesses, Patient’s Choice of Colorado and Live Green Cannabis, and they are about as transparent as they come.

Her marijuana is grown in a converted furniture warehouse in an industrial district in Denver. Tucked in with a Safeway distribution center and landscaping company, the growers here permeate the air. The smell of fresh marijuana is everywhere.
