GREEN BAY, WI (WTAQ) - APAC Customer Services in downtown Green Bay says they are looking to fill 275 positions effective immediately. 

The openings at the Green Bay call center will focus on inbound customer service for several Fortune 500 companies. 

APAC Green Bay General Manager Chris Arendt says new contracts, but mostly expanding existing clients led to the growth. 

All the positions include entry level and operations support staff. 

After the new round of hiring, Arendt says they will employ around 1,000 people through the downtown Green Bay location.

APAC also announced recently that it would add jobs at its call facilities in Iowa, Arizona, North Carolina, and New York.
