About the Institute

badge-2.png

Our practice was founded by Dr. Warner in 1996. The practice was renamed from Chest Medicine of Cullman to the Alabama Institute for Sleep Health in 2022 when we focused our practice to the care of sleep disorder patients and expanded to cover a wider geography.


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. In 2023 we responded to the need for sleep specialty care by expanding our Institute to serve Huntsville.

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.
