Frost & Sullivan

Frost & Sullivan was started by Dan L. Sullivan and Lore A. Frost in New York City in 1961. In the 1970s it started a corporate training division, began sponsoring conferences and industry meetings, and opened an office in London. It was sold to David Frigstad in 1993. A sales office in New York was damaged in the September 11 attacks. During the ensuing recession the company laid off 10% of its 700 staff. == References ==
