Wait time was reasonable. medical personnel were very professional - provided needed information, but also made sure I understood the upcoming procedure and preparation. Dr Lyles was excellent, inquired about my health, checked me over and made several good recommendations concerning my upcoming test. Well done."
"My personnel online file had a lot of erroneous data that I did not enter. I corrected some of the info but could not correct it all. I gave the nurse a list of the medication I take but to my knowledge it was not corrected before I left. It said I have/had colon cancer which is incorrect. I would like to see a copy of the corrects I told the nurse about. This should have been done before I left there. Also, a person requesting data over the phone needs to be able to speak English clearly so you can understand what they are asking you."

"I believe that Thomas Lyles, MD is one of those exceptional positive medical professionals. At my first meeting with Dr. Lyles, I found that he listened to my concerns, he explained the procedures and the previous tests result. After the hospital procedure was completed, he carefully explained what had taken place and what were going to be the next steps. I was very pleased with my experience with Thomas Lyles, MD. I know that I can be a hard critic and combining that with an attitude of my innate crankiness with a first visit into the unknown the result can be much less than pleasant. This time (my first time with Dr. Lyle) was a world away from any previous experiences elsewhere. It was good to be treated with professionalism and care. When I say that the doctor and all the other employees made me feel that I was in safe hands and even made me smile when I left, then you can believe they are the best. I am truly grateful and won’t get that awful feeling of dread the next time I need his services. I appreciated Dr. Lyles follow-up and willingness to answer questions both before and after the colonoscopy. He made me feel that I was dealing with a trusted friend. When I need their service again, I know I will be welcomed. Thank you very much! From the front desk to the nurses, and to Dr. Lyles are professional and very thorough. Each and every one of them was courteous, professional, and made my visit as comfortable as they possibly could. I highly recommend a visit to Dr. Thomas Lyles."
