FORT COLLINS, Colorado (February 5, 1998)—Fred Weaver has been named Vice President of the new Customer Satisfaction group at Advanced Energy Industries, Inc. (AE).

Before joining AE on November 24, 1997, Mr. Weaver spent 20 years with Anheuser Busch. His most recent assignment was Operations Manager of the Anheuser Busch plant in Fort Collins, Colorado.
