Weld County has turned into a haven for call centers and promises to continue that standing with expansion planned by companies like TeleTech Holdings Inc.

Englewood-based TeleTech plans to add 200 new customer-service and technical support jobs on top of the 500 positions the company hired when it moved to Greeley earlier this year.

The initial growth came with much fanfare when in January the company officially announced its location at an old Kmart, which the company remodeled. Gov. John Hickenlooper and Greeley Mayor Tom Norton joined TeleTech CEO Ken Tuchman during the announcement.

TeleTech's expansion follows a separate announcement by Afni, a call-center company that also assists customers by email, social media and web chat.

Afni said in February that it would hire 50 new workers to add to its workforce of 400 in Evans. The new employees were to work as customer-care consultants serving clients in the telecommunications industry.

Other Greeley-area call centers include ones operated by StarTek, traded on the New York Stock Exchange, and insurance giant State Farm.
