Creating a greater understanding of sleep disorders and healthy sleep is a mission for Dr. Chandra. He is regularly interviewed for print and broadcast media on sleep disorders. In 2008, he helped one of his patients organize Chattanooga’s first chapter of AWAKE (which stands for Alert, Well, And Keeping Energetic), a support group for people with apnea and other sleep disorders.
