Di & Jay Czarkowski Signature


Meet Our Team


Diane Czarkowski, Founding Partner

Before entering into the cannabis industry, Diane’s career included more than a dozen years in the high tech industry as an executive salesperson responsible for multi-million dollar quotas. In 2003, she and her husband Jay started their real estate development company and were very successful developing, building and selling real estate in ski resorts and the front range of Colorado.

When the real estate market began to collapse, she and Jay pivoted into the newly born cannabis industry in Colorado and opened a dispensary and cultivation center in Boulder, CO. Her responsibilities focused on business operations, compliance and patient¬ related operations. Their operation quickly became one of the most reputable businesses in the state, earning one of the first state and local cannabis licenses.

Canna Advisors was created in 2013 as a cannabis consulting business to assist start-ups in other states with the complex and competitive state licensing process. Today Canna Advisors is recognized as a leader in the consultancy space, having one of the best track records in the industry, winning cannabis licenses in the most regulated markets including Connecticut, Massachusetts, Nevada, and Illinois.

Diane is a founding member of the National Cannabis Industry Association, a founding member of Women Grow, a lifetime member and selection committee member of the ArcView Investment Group, a mentor for Canopy Boulder, and a sustaining member of Americans for Safe Access, and Students for Sensible Drug Policy.

Jay is a licensed General Contractor with previous businesses in real estate development. In 2009, he and his wife, Diane, founded Boulder Kind Care (BKC) a medical marijuana business with a retail center and cultivation facility. His focus centered on production operations.

One of the keys to success at BKC was the ability to consistently produce large amounts of high quality, pharmaceutical¬ grade cannabis. It was Jay’s vision, designing state-of-the-art facilities and processes that led to BKC’s success. In the spring of 2012, Jay and Diane sold their business in order to dedicate their time to business consulting and advocacy.

Canna Advisors has achieved great success assisting clients across the county in obtaining competitive state licenses, assembling key industry talent and designing state-of-the-art cultivation facilities. Recently, a Canna Advisors client in Nevada was one of three licensees in the state to be approved for cultivation in a greenhouse – a testament to the quality of the facility design.

Jay is often featured as a prominent speaker in national cannabis industry events, sharing his expertise in designing environmentally efficient cultivation facilities and understanding the disruptive technology that is being brought into the industry such as automation and horticulture methodologies.
