Andrew founded the Oregon Cannabis Law Group in 2014 and merged with Green Light Law Group in 2019. He has long been on the forefront of the novel legal issues concerning the emerging cannabis industry. Andrew represents and advises cannabis business clients on state law compliance and licensing issues, as well as in civil litigation and private arbitration. In 2019, Andrew led the Green Light Law Group legal team that prevailed against the Oregon Liquor Control Commission in the Oregon Court of Appeals, striking down Oregon’s short-lived ban on flavored cannabis vape products.

Andrew was born and raised in Port Townsend, Washington. He graduated cum laude in 2008 from the University of Miami School of Law, and practiced in Miami, Florida until he moved to Portland in 2013.

Andrew holds a bachelor’s degree and a Performer Diploma from the Indiana University School of Music and was formerly a professional-caliber orchestral violist who has toured throughout Europe and the Americas. His primary instrument is the “Eclipse” viola, which he commissioned from the luthier Thomas Gaetano Sparks. He enjoys spending time with his wife and two kids, chasing down old dime store novels and rare 1970’s sci-fi first editions, and sampling typical beverages of the region.
