"Dr Lewis recently did a colonoscopy for me. He and his staff were awesome. Professional, friendly & caring. ... He called me personally on the 3rd day at home to let me know that the polyps were benign."

Healthgrades (Dr. Thomas Lewis)

"Every time I've called there (at least 10 times) they put you on hold for 10+ minutes. I had a question for a nurse before a procedure I was to have and no one called back."

Healthgrades (Nashville Gastrointestinal Specialists)

"I saw Dr. McMillan after approximately 6 months of GI issues and he told me I wasn't sick enough for him to be concerned... He spent less than 5 minutes with me and I felt that he gave very little attention to my health or medical concerns."
