About Dr. Frank Montag

Clients turn to Frank when they need a competition lawyer with authority, a global reputation and extensive knowledge of the world’s competition law regimes. 

Frank draws on over 30 years’ experience to defend his clients’ interests in EU and multijurisdictional competition procedures and investigations.

With increasing intra-agency co-operation in merger and cartel investigations, clients need a globally co-ordinated defence. Frank’s practice has brought him before the European Commission, Germany’s Bundeskartellamt and other key global authorities, including the US DOJ and FTC and China’s Mofcom, in some of the most complex merger transactions and investigations into anti-competitive practices. He is also an experienced litigator before the European courts in Luxemburg.

Frank speaks German, English and French.
