Sean McAllister is an expert in cannabis administrative and regulatory law. Sean helps clients understand the complex web of overlapping regulatory and administrative law rules, and he has been integrally involved in the legislative and rulemaking processes for more than a dozen years in Colorado.

Sean has handled more cannabis discipline and enforcement cases than any other law firm in Colorado. Sean is the only lawyer to successfully defend and lift a summary suspension against a licensed cannabis business, resulting in a multi-million dollar company re-opening after it was wrongfully shut down. Sean has represented numerous clients alleged to have violated pesticide rules and have litigated pesticide standards against both Denver and the Colorado Department of Agriculture, releasing millions of dollars of marijuana from pesticide holds. Sean also regularly handles other rules violations, such as underage sales, violations related to cannabis extraction operations, and unauthorized modifications of premises.

Sean is often called upon to act as regulatory counsel in large cannabis and hemp transactions. Sean’s deep knowledge and practical understanding of how the rules work allows companies to efficiently execute transactions. Sean is happy to work in conjunction with in-house counsel or other law firms to provide a regulatory lens on transactions, though the firm also handles significant transactions on its own.

In addition, Sean has years of experience helping businesses obtain licensure for all types of licensed marijuana businesses including cultivations, dispensaries, infused product manufacturers, and transporters.
