KINGSPORT — Ballad Health Executive Chairman, President and CEO Alan Levine launched a vigorous defense Thursday of the healthcare provider’s announced move to regionalize and realign services amid pushback from local governments and attacks — some of them personal — on social media. In a meeting with members of the editorial boards of the Kingsport Times News and Johnson City Press, Levine and members of his Ballad Health management team emphasized that the changes are data-driven and will ultimately improve healthcare in the region. “These attacks are wrong,” Levine noted. Levine said a previously planned meeting to talk with Sullivan County commissioners about the changes has now been canceled.
