Mathieu’s work has focused on the transactional side of sports law, where sponsorship agreements, media rights, venue operations and governance increasingly shape an organisation’s commercial future.
A report says his discussions with Foley Hoag centred on combining the client base he had developed with the firm’s wider infrastructure. That makes the move more than a change of office: it is an attempt to turn an individual practice into a nationally recognised offering.
The sports and entertainment group reportedly begins with several partners and associates, with Mathieu expecting the team to grow. His ambition is to put Foley Hoag among the leading names in a market that serves clubs, leagues, athletes and major sports organisations.
“Mesmo que a Foley Hoag não seja uma firma gigante, ela funciona muito como a maioria das grandes,” Mathieu said. He also described the opportunity in simple terms: “A plataforma é fantástica para mim.”
That combination of scale and flexibility appears central to the appeal. Foley Hoag may not be one of the very largest firms, but Mathieu believes its structure can support a substantial national practice without losing the specialist focus sports clients demand.
For teams and leagues, legal work now stretches well beyond disputes. Sponsorship deals, commercial partnerships, intellectual property, employment matters and governance decisions all require advisers who understand the business of sport as well as its legal framework.
The next test will be whether Mathieu can turn this reported arrival into sustained growth. New hires, major mandates and deeper relationships with clubs and leagues will determine whether the move becomes a personal career step or the foundation of Foley Hoag’s next major sports-law platform.
