The Horizon Sleep & Epilepsy Center

Another small part of our vision came true recently — we have grown. We now have a state-of-art Horizon Sleep & Epilepsy Center in Atoka TN, right next door to our already established facility Horizon Gastroenterology & Neurology PC. Taking care of her patients with sleep disorders using the latest medical technology available, along with excellent patient care, was definitely a-dream-come-true.

"I hope with the launch of my own sleep lab I can work more diligently in treating my patients with sleep disorders. Nothing gives me greater pleasure and satisfaction than seeing my patients return to normal sleep patterns and succeed in their daily lives." — Dr. Shameela Ahmed

Our History

Horizon Gastroenterology & Neurology was established under the name of The Gastrointestinal and Liver Clinic in June 2007 by Dr. Muhammad S. Siddiq. In September 2008, it became a multi-specialty clinic when Dr. Shameela Ahmed, a neurologist, joined the practice. Since then, the clinic has branched out and has added two new locations in Midtown (Memphis) and Covington. We are now proud to offer more investigational and therapeutic procedures.
