Frank A. Segall



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 of two leading cannabis operators in a four-way merger resulting in the largest vertically integrated cannabis platform in the state of California. He has also been involved in not only structuring but sourcing on behalf of his clients hundreds of millions of dollars in financings for cannabis operators and closing those financings for both lenders and borrowers throughout the country, making him one of the most experienced finance attorneys in the space. Furthermore, Frank represents ancillary companies in cannabis such as a leading FinTech company providing software solutions to cannabis operators, and the leading 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. These representations are just a few of the transactions Frank and his team have successfully completed as a result of his pioneering efforts and deep experience in the cannabis 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.

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.
