Expansions in Northeast Georgia are what will keep Gainesville’s hospital afloat in an increasingly difficult environment, Northeast Georgia Health System President and CEO Carol Burrell said Monday. The hospital opened Medical Plaza 400 in Dawson County this past spring, and it is “going gangbusters,” Burrell told a Rotary Club crowd gathered at the First Baptist Church of Gainesville. The health system is also on schedule with its planned hospital campus in Braselton, with a second medical office set to open next spring.
