About Us



About the Institute
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 November 2024, we opened the sleep lab in Cullman to provide high quality, low cost outpatient sleep studies all under one roof.
Dr. Warner continues to serve as an assistant professor of medicine at UAB School of Medicine and assistant clinical professor at Alabama College of Osteopathic Medicine.
Our goal is to glorify Christ and assist our patients with their medical and spiritual needs.
