Fennebresque, an M&A banking veteran of 30 years for UBS AG, Cowen & Co., Lazard Freres & Co. and other firms, joined Dahlman in 2010 as chairman.  The firm had grown over the past 2 years, and his joining then was characterized as a move to bring in more seasoned Wall Street experience.  Up until Rose departed, the firm had been on a hiring spree.  However, many of those recent hires subsequently left, while Fennebresque has made some new hires.
