    Frank, a French-qualified lawyer and a member of the Brussels bar, has been recognized by The Legal 500 EMEA in its “Competition: EU and Global” category. He rejoins O’Melveny from Gibson Dunn, where he was a partner in the firm’s Antitrust and Competition Practice Group. Earlier in his career, he was counsel in O’Melveny’s Brussels office, making his return a significant homecoming.

    According to a statement from O’Melveny chair Bradley J. Butwin, the firm is pleased to welcome Frank back, particularly at a time when the European Commission is playing an increasingly central role in competition enforcement. Butwin highlighted Frank’s “broad skillset, sharp technical abilities, and extensive experience with EU antitrust matters” as valuable assets to the firm.

    Frank expressed his enthusiasm about rejoining the firm, noting his appreciation for O’Melveny’s platform and the opportunity to collaborate once again with its antitrust team. Per a statement, he looks forward to contributing his expertise to the firm’s global practice.
