John Curtis

COO / Master cultivator

In his time as a fixture of the medical marijuana movement for the past two decades, John Curtis has had a front-row view of the changing marijuana landscape. His interest began as a student when he interned with renowned marijuana author, advocate and educator Jack Herer. He then went on to become a journalist for a major U.S. market, frequently interviewing politicians and prominent figures of both local and national importance. In 2005, he left journalism to purchase a 40-acre sustainable food production farm located an hour southwest St. Louis, nurturing his lifelong love of gardening. In 2009, he sold his farm and relocated to Boulder, CO to open his first medical marijuana dispensary and grow operation, becoming one of the first state-licensed facilities in Colorado. Today, he brings his marijuana cultivation expertise to Beleaf, having been an integral part of the company since the beginning of their CBD production in 2015. In addition to his leadership at Beleaf, John is currently a partner in the consulting firm Creative Cannabis Consultancy, as well as the Founder and Chairman of the Board for the Missouri Cannabis Trade Association.
