NewStar Financial, Inc. announced that it has hired veteran banker Mark Denomme as a managing director in its Leveraged Finance group. Denomme will join NewStar’s Boston office and have responsibility for generating new financing opportunities with mid-sized companies, private equity firms and other investors in the middle market.

Denomme has more than 20 years of business development and transaction experience working with private equity groups and other private business owners to finance a wide range of middle market companies. Prior to joining NewStar, Denomme was a managing director at Hercules Technology Growth Capital, where he helped launch the company’s lower middle-market team, providing senior debt and junior capital to mid-sized companies in the technology, healthcare and business services sectors. In that role, Denomme managed a business development team while also maintaining individual client coverage responsibilities. Previously, Denomme co-founded Consilium Partners, a boutique investment banking firm specializing in sell-side M&A for smaller middle market companies. He also worked for FleetBoston Robertson Stephens and its predecessors in a variety of roles including as a Director in its Leveraged Finance group.

“I am very excited to join an established team that is so well positioned to capitalize on lending opportunities in the middle market,” said Denomme. “I am also looking forward to working with the NewStar team to continue building on its established direct origination franchise as we broaden our coverage of mid-sized companies, private equity firms and intermediaries in these attractive markets.”

“We are pleased to add a banker of Mark’s caliber to our team in Boston as we continue to enhance our coverage of financial sponsors and key industry sectors,” said Tim Conway, NewStar’s CEO. “He has valuable credit experience and a sophisticated view of our markets. Adding Mark to our direct lending franchise reinforces our position in the marketplace as a smart, reliable partner at a time when we are increasing our lending activity across the country,” Conway added.
