Dirk has a broad practice covering the needs of the financial industry, focusing largely on banking and regulatory aspects of domestic and multi-jurisdictional M&A, restructurings and other transactions, as well as on a wide range of finance and debt capital markets matters.

Dirk advises banks and other financial institutions, insurers and asset managers on matters of strategic importance, especially in relation to acquisitions and disposals of banks and portfolios, complex restructuring and resolution measures of financial institutions, as well as regulatory implementation and enforcement, and other areas of regulatory scrutiny. In particular, he has acted on many transactions involving troubled or failing institutions, including major transactions of the financial crisis including the set-up of bad banks for WestLB and Hypo Real Estate Group, and advised on all the bail-out, restructuring and transformation measures in relation to WestLB (now Portigon) and the reprivatisation of Deutsche Pfandbriefbank. Dirk also advises domestic and foreign governments and public institutions.

In debt capital markets, Dirk acts for issuers, banks, dealers and investors on a broad range of transactions including bonds, debt issuance programmes, registered notes (Namensschuldverschreibungen), Schuldschein loans, commercial paper, Pfandbriefe, and other covered bonds and structured finance matters, as well as securitisations, portfolio financings and repackagings.

Dirk currently serves as Co-Managing Partner of the firm (since 2014).
