About the Institute

badge-2.png

Chest Medicine of Cullman was founded by Dr. Warner in 1996. The practice was renamed Alabama Institute for Sleep Health in 2022 when we focused our practice to the care of sleep disorder patients.


The practice was established to offer residents of North Alabama the high quality subspecialty care that was previously available only in large cities or academic institutions.

Dr. Warner continues to serve as an assistant professor of medicine at UAB School of Medicine and clinical faculty at Alabama College of Osteopathic Medicine.

Our goal is to glorify Christ and assist our patients with their medical and spiritual needs.
