Consulting firm Oliver Wyman has acquired TeamSai to expand its aviation group.

TeamSai, headquartered in Atlanta, provides consulting and technical services to the aviation and aerospace industries, specializing in maintenance advisory, supply chain, certification and compliance and technical support services.

New York-based Oliver Wyman will integrate the company into Cavok, its aviation technical services and consulting unit. The buyer is a subsidiary of Marsh & McLennan Cos. (NYSE: MMC).

Other recent advisory deals have come from Los Angeles investment bank Houlihan Lokey, which added Bridge Strategy Group in January, and the Doneger Group's purchase of Huepoint, a color trend-forecasting firm, in December.
