Diamond Castle is a private equity investment firm that was founded in 2004 by a group of senior investment professionals from DLJ Merchant Banking Partners. While at DLJ Merchant Banking, our founders helped create one of the preeminent private equity businesses in the world, a business that successfully raised three generations of leveraged buyout funds with over $9 billion of capital under management.

Diamond Castle targets investments in the following industry sectors: energy & power, financial services and healthcare. We build our industry specializations around our Operating Partners, who average more than 25 years of direct experience within their respective industries, as well as our team's investment acumen and experience. We also maintain the flexibility to invest outside of our targeted sectors in order to take advantage of opportunities across a broad range of industries. We invest in a wide variety of transaction structures, including leveraged buyouts, recapitalizations, growth capital and equity-like investments in both public and private companies. Our flexible investment mandate allows us to seize and capitalize on private equity opportunities regardless of industry sector or the form of the transaction.

Diamond Castle invests on behalf of a diverse group of investors, including some of the largest domestic and international public and corporate pension funds, university endowments, foundations and high net worth individuals. Our team has committed substantial personal capital to Diamond Castle in order to align our interests with those of our investors and our portfolio company management teams.
