Frank A. Segall

Organization Profile
Professional Biography


With a strong background in finance and business operations, Frank A. Segall negotiates complex business deals, including mergers, acquisitions, sales, syndications, loans, restructuring, and equity investments. He works as outside general counsel to businesses throughout the world and has vast experience in a broad base of sectors, such as manufacturing, technology, transportation, and retail. In 2022, he was named a “Cannabis MVP of the Year” by Law360 and a “Go To Business Transaction Lawyer” by Massachusetts Lawyers Weekly.

Frank is nationally renowned for his pioneering work with the cannabis industry—he was one of the first prominent corporate lawyers to enter the cannabis industry in 2012. From there he co-founded and led one of the first major cannabis business practices at a corporate law firm and has been at the forefront ever since. Over the years, Frank has developed a national practice for this fast-growing industry, assisting with such matters as business formation and corporate structuring, capital raising, and mergers and acquisitions.

For example, Frank led the sale a leading cannabis retailer to a cannabis enterprise that resulted in the largest and most vertically integrated cannabis platform in the state of California. He also led the formation and launch of a first-of-its-kind consumer service, a digital credit and loyalty-enabled payments solution in the state of Massachusetts. Finally, under his leadership, his prior firm represented a provider of advanced cultivation and extraction solutions in the cannabis industry in its acquisition of two of the leading brands that provide equipment and solutions for extraction, post-processing, and testing for the cannabis and hemp industry. This representation was possible due to Frank’s deep experience in the industry.

Frank’s colleagues describe him as “the ultimate networker” who creates business opportunities for anyone who comes into his sphere of influence and friendship. Intensely loyal and deal-smart, Frank knows how to open doors, make connections, and get things done.

Outside the Firm

Alongside his family, Frank has fundraised $1.5 million for the Crohn’s & Colitis Foundation and was honored with the 2021 Modell Award for his dedication to the furthering of the organization’s mission.
