• Four Corners Sleep Disorders Center

  • Mercy Regional Medical Center's Sleep Disorders Center offers a wide range of diagnostic services in the rapidly growing field of sleep medicine. The Center is primarily focused on sleep-related breathing disorders.


    The sleep laboratory utilizes highly sophisticated testing equipment and technologists who have extensive experience conducting and analyzing sleep data.

    Public awareness of the consequences of inadequate rest has risen dramatically over the last several years. Our sleep center is committed to excellence in our sleep disorders testing service, but we also recognize the important role sleep education has in promoting, achieving, and maintaining healthy lifestyles. To that end, we strive to provide our patients with information that will enable them to make sound decisions about their own (or family members') well being.
