Gainesville and Hall County officially welcomed one of its newest business members into the community Friday as the severed ends of a ribbon fell to the ground at ProCare Rx.Founded in 1987, ProCare Rx, a national pharmacy benefit management company, moved its headquarters to Gainesville earlier this year from Duluth, bringing with it 120 employees. Its office is the cornerstone of the ProCare Park, a 23-acre site on Candler Road at Interstate 985. “We are glad to be here and are thankful for the opportunity,” said Roger Burgess, founder, chairman and CEO of the company.
