The companies whose senior executive officers were represented include, among others, Sunbeam, Kmart, Jeffries, and MetLife.

At the request of the U.S. Commodity Futures Trading Commission, the Honorable Gerard E. Lynch (then SDNY) and the Honorable George B.

Brian concluded his private practice career at Carlton Fields.
