Dr. William Lyday

Physicians go back many generations in Dr. William Lyday’s family, so you could say it’s a hereditary trait. His great grandfather and grandfather were Internal Medicine and OB doctors in rural North Carolina, his dad a thoracic surgeon, and he’s the first gastroenterologist.

After completing his undergrad degree at UGA, Dr. Lyday went back to North Carolina for med school at UNC Chapel Hill with the intention of becoming a surgeon.

A problem-solver by nature, he soon discovered his love of figuring things out made him a better fit for an investigative, diagnostic, patient-centered role. With its connection to all the major systems in the body, gastroenterology was the perfect area of specialization.

Following his fellowship and residency, he soon found himself back in Georgia, highly interested in all the new technology being introduced in the Atlanta area. Since the early 2000s, Dr. Lyday’s been practicing in the GI field with a focus on nutrition, research, and innovative procedures.

He started GastroATL in 2017 in order to create a practice where the medical team could focus on three things:

  • Being thorough, looking at root causes and underlying factors to uncover the sources of GI issues.
  • Being comprehensive, addressing problems from all angles, including heredity, diet/nutrition, and mental health.
  • Being Collaborative – building teams of experts to provide integrated care.

Dr. Lyday is board certified in Gastroenterology. Over the years, he’s enjoyed many affiliations, including with Atlanta Health Institute, Atlanta Community Clinical Oncology Program, Georgia Institute of Technology, and Cancer Treatment Centers of America. He’s currently affiliated with Emory St. Joseph’s Hospital, Northside, and Piedmont Hospitals.

When he’s not working, he enjoys fitness, golfing, and comedy clubs. (Sometimes laughter is the best medicine!)
