Healthcare staffing provider Jackson Healthcare announced a 306,000 square foot expansion project of its corporate headquarters in Alpharetta, Ga., which will accommodate 1,400 new associates. The company will break ground on the $100 million project in the winter of 2017.

The headquarters expansion includes an eight-story, 267,000 square-foot office building and a 39,000 square-foot amenities building that will house a gym, an indoor pool and a restaurant for associates. It will also have room for future childcare accommodations.

The three-story amenities building, inspired by the Roman Colosseum, will be the centerpiece of an Italian piazza for the headquarters campus. The project will also include a 1,385 car parking deck designed to resemble the buildings that line the Piazza del Campo in Siena.

“We are building this for our associates,” said President Shane Jackson “This is for them to enjoy. The quality of service we give our customers is directly related to the quality of the people within our company. We want them to have a beautiful place to work together.”

Jackson Healthcare currently employs 1,100 workers nationwide including 898 associates in the Atlanta area. The company reported annual revenue of $798 million in 2015 and ranks fourth on Staffing Industry Analysts’ 2016 list largest healthcare staffing firms in the US.
