Ray Carveth
Adjunct Board Member


Ray is a supervisor for the Local Hazardous Waste Management Program in King County, Washington.  He became a member of NAHMMA during it’s formation and has been a member ever since.  He’s held every office on the board except secretary.  As President he initiated the annual Board of Directors planning retreat.  He’s received numerous local and national awards for environmental achievement and community service.  In his “spare” time, he owns a small business called Purpleink Solutions that helps non-profit groups understand the art of moving from ideas and vision to implementation and service.   In this capacity, he was recently appointed the strategic business advisor for the newly legal Cannabis industry in Washington State.  He’s probably best known for his NAHMMA awards presentations for both the serious awards and the rather creative (or just plain odd) golden bung awards presentations.
