Dell Inc. (DELL) announced Friday it will add up to 1,000 jobs in Tennessee as it expands customer service operations.

Dell already has a technical support call center, sales operations and a distribution center for the eastern U.S. in Nashville and a manufacturing plant making Dimension and OptiPlex desktop computers in the nearby suburb of Lebanon.

"Our continued Americas growth, combined with the quality of this area's work force, made the decision to expand our operations here an easy one," said Dell CEO Kevin Rollins, who along with state and local leaders made the announcement in at Dell's Nashville facility.

"Today's announcement reconfirms our commitment to keeping Nashville and Middle Tennessee as one of our primary operations sites in the Americas region."

Dell also announced that Tennessee Titans quarterback Vince Young, the No. 3 pick overall in the NFL draft, would support an after-school program in Nashville that Dell helps sponsor.

Dell started its Tennessee operations in August 1999 with about 200 production sales and call center employees, and the work force has grown to 3,500.

The new jobs are expected to be created by the end of the year, officials said.
