Diamond Castle Holdings is a New York-based private equity firm specializing in leveraged buyouts and growth capital investments in middle-market companies.

Diamond Castle Holdings is a private equity firm founded in 2004 by Lawrence Schloss along with four senior members of DLJ Merchant Banking Partners (DLJMB). The firm was established as a spinout from Credit Suisse, where the founding team previously operated. The firm is based in New York City and maintains a strong heritage rooted in the merchant banking traditions of Donaldson, Lufkin & Jenrette.

The firm primarily focuses on leveraged buyout and growth capital investments in middle-market companies. Its investment activities span several key sectors, including media, healthcare, financial services, and power and industrial sectors. Since its inception, the firm has raised significant capital, notably closing its Diamond Castle Partners IV fund at $1.85 billion in 2006, which was named in succession to the three funds previously raised at DLJMB.
