WellStar Health Systems has announced that Gary Miller will become chair of the WellStar board of trustees on July 1. Miller, president/CEO of GreyStone Power Corp., will take over for Janie Maddox, whose two-year term as chair expires this year (she will remain a board member). Miller has worked at GreyStone for 20 years; he is a certified public accountant and holds a law degree from Georgia State University. He has been on the WellStar board of trustees for 11 years. Over the years, I have seen the impact WellStar has on our community, he said. I will continue to work with the board and the WellStar leadership team as we build on the vision for the system: to deliver world-class healthcare.
 
Along with Millers appointment, David Hafner, M.D., will become vice chair, effective July 1. Dr. Hafner is in line to take over as chair of the board of trustees when Millers chairmanship ends in 2016. Dr. Hafner is a partner at Vascular Surgical Associates, PC, in Marietta and serves as the medical director of WellStars vascular lab.
