Trenwith Group, a New York-based investment bank, announced three new hires to the firm’s recently-opened Philadelphia office.

The new hires are senior vice president David Bookbinder, vice president Robert Metzfield and senior associate Gerald Cullins Jr.

The Philadelphia team will provide valuation services, including capital stock and derivative securities, intangible assets, regulatory compliance and corporate planning.

Trenwith CEO Ron Ainsworth said, “In recent years, Trenwith has enjoyed significant growth as middle-market companies opt for M&A activities over IPOs and are in need of advisory and valuation services. We have been working with Philadelphia-based clients for a number of years now and we are pleased to be establishing a permanent presence in this important market.”

Prior to joining Trenwith, Bookbinder was a vice president at Management Planning, developing and implementing the firm’s corporate valuation practice. Bookbinder received a Master of Business Administration degree from Drexel University.

Metzfield comes to Trenwith from Grant Thornton, where he was a senior manager. Metzfield received a Master of Business Administration degree from Temple University.

Cullins was previously a senior valuation consultant at CBIZ Valuation Group. Mr. Cullins received a Bachelor of Arts degree from Stockton State College.

Trenwith Group owns wholly-owned subsidiaries Trenwith Securities and Trenwith Valuation.
