Hi. There are two specialists I highly recommend who worked closely with Dr. Lloyd and who have been lifesavers to me: Dr. Thomas Doyle, a pediatric cardiologist at Vanderbilt Children's Hospital. He has performed three heart caths / lung stenting surgeries on me and is expert on the impact of this disease. In addition, pulmonologist Dr. Tufik Assad, who studied under Dr. Lloyd. He is with the Williamson Medical Group in Franklin. He and Dr. Thomas have worked as a team on my care. Hope this is helpful.
