About Greenhill & Co. LLC

Greenhill, which closed its acquisition by Tokyo-based Mizuho Financial Group in November 2023, calls itself “a unique investment banking firm,” and to be sure, it follows a model quite unlike the structure of its behemoth competitors. The firm (which kept its name and leadership team in place following the Mizuho deal) focuses primarily on its advisory work, which includes mergers, acquisitions, restructurings, financings, capital raisings, and secondary fund investment sales. 

Greenhill is a relatively young one by Wall Street standards: about 28 years old. In 1996, Robert F. Greenhill, former head of Smith Barney and former president of Morgan Stanley, struck out on his own and founded an eponymous boutique firm. He led the company for 11 years before stepping down as CEO in October 2007. 

Today, Scott Bok is the chairman of Greenhill Advisory, reporting to Jerry Rizzieri, President and CEO of Mizuho Securities USA and Head of the Americas’ Corporate & Investment Bank. Kevin Costantino and David Wyles co-head Greenhill, and Patrick Suehnholz serves as its COO. 

Greenhill is headquartered in New York, and has additional offices in Chicago, Frankfurt, Hong Kong, Houston, London, Madrid, Melbourne, Paris, San Francisco, Singapore, Stockholm, Sydney, and Toronto. It employs approximately 370 people, including more than 80 managing directors.
