We are Relentless Advocates for Your Cannabis Business.

As the green rush changes the landscape of business opportunity in Massachusetts, we'd like to help you enter the marketplace as quickly and painlessly as possible. We will work to accommodate you at every level—we'll even come to your home or office so you can focus on your goals, not traffic.

Our approach to legal and business advising is a blend of the old-fashioned and the modern. We believe that the captains of industry that came before us had it right: taking the time to learn about you as an individual so that we may truly understand your company's vision is absolutely worth every minute. By applying modern research techniques and social media technologies, we are able to remain a rapidly adaptable team that knows cannabis, the law, and Massachusetts. We are adept at communicating with people of all walks of life, from state and local officials, to bud trimmers, to the inevitable anti-cannabis contingent. 

The Mensing Group LLC is the first, and only, homegrown legal and business advisory firm solely dedicated to cannabis in Massachusetts. We are proud to limit our practice to the exclusive service of Massachusetts cannabis business clients and we bring that singular focus to bear on the important issues facing our clients.
