An appointment must be made with one of our sleep specialists (Dr. Joyce Wade-Hamme, Dr. Billy Williams, Dr. William Frazier, or Dr. Rajesh Patel) in order for a patient to be evaluated and considered for a sleep study (polysomnogram). This appointment may be made either by physician referral or directly from a patient who may be experiencing symptoms of sleep-related disorders. Please call 601-352-2273 for more information. We will be happy to assist you.
