Dresdner Kleinwort Wasserstein has hired David Madon, a former senior credit derivatives banker at Commerzbank, as a managing director of its New York-based structured credit sales and marketing group as part of an effort to build its North American investor base.

Madon, who joined Commerzbank in New York from Crédit Lyonnais in July 2003 and was most recently head of credit structuring and origination, started work at Dresdner Kleinwort Wasserstein this month.
