About StoneGate

StoneGate Capital Group History

StoneGate’s business was originally formed as Hartstone & Dickstein Incorporated in 1982. Renamed StoneGate Capital Group in 1994, the Group has continued to provide strategic business and transactional advice and consulting services, principally regarding new company development, business expansions and acquisitions; exit strategies; operating reorganizations; financial restructurings; and other transitional situations. In addition, StoneGate can provide crisis management for companies requiring an immediate management change.

StoneGate is best known for its work in the media industry, especially radio, television, and Internet. However, its projects have involved companies in a wide spectrum of other industries, ranging from medical devices to general aviation aircraft. Over the last 35 years, StoneGate has guided its clients through nearly $3 billion of transactions, involving hundreds of businesses.

In earlier careers, StoneGate principals structured tens of billions of dollars of financial transactions, involving dozens of industries.
