Trinity International strengthens its International Arbitration team

Trinity International, a law firm recognized for its expertise in emerging markets, is pleased to announce the arrival of Florian Quintard as Partner and Rayan Keyrouz as Counsel in its Paris office.

Florian Quintard, dual-qualified in Paris and England & Wales, brings his expertise in international arbitration, particularly in the construction and energy sectors. Florian will further develop the firm’s arbitration practice and assist clients in resolving complex disputes.

Trinity International’s Paris office significantly strengthens its international arbitration practice with two strategic hires. Florian Quintard joins as Partner and Rayan Keyrouz as Counsel. These arrivals enhance the existing practice, led by Partners Stéphane Brabant, Natasha Peter, and Lucien Bou Chaaya, alongside Senior Associate Ben Ainsley Gill, and Associates Francesca Ngahane, Yalda Khalifé, and Mama Sahale Souaré. The expanded team will work closely with the project and corporate departments, focusing on risk prevention and crisis management. This development reflects Trinity Paris’ ambition to build a strong arbitration practice to address complex disputes with innovative and pragmatic approaches.

Their respective expertise in institutional arbitration proceedings (including ICC, ICSID, LCIA) and ad hoc procedures, combined with their experience in pre-litigation management and alternative dispute resolution mechanisms, make Florian and Rayan a strategic asset for the firm’s growth. Trinity International strives to offer comprehensive services (projects, financing, corporate, tax, litigation) to support its clients in emerging markets, particularly in key sectors such as energy, infrastructure, and natural resources.

Florian Quintard has advised numerous clients on major construction cases related to infrastructure and energy projects, including Algeria’s East-West Highway, the ITER project, and the Flamanville EPR.

Natasha Peter, Partner, stated: “The arrival of Florian and Rayan is a natural addition of skills and expertise. With their versatility and dynamic personalities, they embody Trinity’s DNA, centered on excellence and the quality of client relationships.”

Florian Quintard, Partner, commented: “Trinity offers an international environment with a human scale that fosters innovation and the development of a dynamic practice. Everything is designed to encourage the autonomy of partners within a collaborative framework. This environment will allow me to contribute to the growth of Trinity’s arbitration team and provide our clients with innovative solutions, prioritizing early dispute resolution to achieve amicable settlements for major conflicts.” He added:“With its exceptional growth in recent months, Trinity is committed to making its arbitration team a market leader, and further notable hires are to be expected in Paris and other offices.”
