Your Green Contractor is the nation’s leading commercial general contractor specializing in the build-out of all types of marijuana facilities. Projects include dispensaries, MIP kitchens, indoor cultivation centers, extraction rooms, greenhouses, and labs. In 2011, a phone call from an architect we had worked with for years, turned into a whole new adventure.  After completing a simple remodel of a dispensary just a few blocks from the state capitol building in Denver, our client asked us to expand one of their grow facilities.  From just one visit to the grow facility, the need for a more innovative, professional approach to Marijuana facility construction was obvious. We quickly assembled a specialized team of construction professionals to service this booming industry in a way that had never been done before.  YGC was born!


Nathan Mendel – President

Nathan is the founder and President of Your Green Contractor (YGC), a wholly owned subsidiary of Mendel and Company Construction. Prior to starting his own company in 1997, Nathan worked for his uncle at Mendel-Allison Construction.

Michelle Koster – Business Development

Michelle began her career in construction when she was 18. She was always intrigued by watching large earthmoving equipment which led her to her first job as a flagger. She soon moved on to obtain her CDL so she could drive trucks and work as a laborer.
