At Tennessee Comprehensive Lung and Sleep Center, Dr. Clyde Southwell has made it his mission to help Sumner County rest and breathe easier. There’s really nothing like a breath of fresh air and a good night’s sleep. Deprived of either, a person’s daily functions, health and quality of life can quickly deteriorate. We are one of the only, if not the only sleep center in this area that has been accredited by the American Academy of Sleep Medicine. We want each patient to know that they are getting the very best treatment available when they come to our facility. Tennessee Comprehensive Lung and Sleep Center creates an opportunity to the world of clinical research in the field of pulmonary medicine, internal medicine, and sleep medicine.
