Founder/Shareholder

Sean T. McAllister is one of the nation’s leading marijuana lawyers and he is one of the only major marijuana lawyers licensed to practice law in both Colorado and California. Sean has twenty years experience working on marijuana law reform. He founded the non-profit Sensible Colorado that worked on all the ballot initiatives in Colorado that culminated in recreational legalization in 2012. Sean represented some of the first dispensaries to emerge in Colorado beginning in 2009 and he has built a reputation as an aggressive and pragmatic advocate for his clients.

Sean has litigated several groundbreaking marijuana cases in Colorado. Sean has sued regulators over enforcement actions, litigated pesticide standards for marijuana grows at the state and local level, and negotiated settlements for some of the most serious marijuana rules violations. He was co-counsel on the case suing the Colorado Department of Public Health and Environment in 2008 that overturned the original 5 patient limit. This lawsuit broke open the medical marijuana industry and led to the opening of dispensaries. He litigated a ban on medical marijuana dispensaries in Eagle, Colorado and authored a ballot initiative that ultimately led to the ban being overturned by a vote of the people. He has sued several cities and counties related to their implementation of the marijuana law on behalf of aggrieved clients.

In Sean’s role as corporate counsel to dispensaries, he handles all aspects of corporate formation, dissolution, governance, purchase agreements, promissory notes, civil litigation and land use matters. Sean has also represented several dispensary owners and employees charged or accused of criminal violations in state and federal court. In addition, he has pioneered complicated licensing agreements with celebrity personalities.

Currently, Sean is defending the nation’s first product liability action against a marijuana manufacturer.
