"Several years ago I met him under duress with something stuck in my throat he performed the EGD with no trouble since. Has also done a colonoscopy in the past. He's a professional I will continue to be under his care."

"Dr. Nightengale has been my gastroenterologist for over 20 years. In my opinion he is as knowledgeable in his field as any person could be. He is very efficient in his consultations with you. No questions left unanswered. I have had multiple EGD’s as well as colonoscopies and his review of the results is always very thorough. I highly recommend Dr. Nightengale."

"Egd and colonoscopy went just as planned and so far I haven't had a problem Staff was very nice. Awaiting biopsy results but they gave piece of minds that everything looked normal. Bowel prep was WAY easier with plenvu than what I have used before. Dr Blankenship was very nice! All staff involved were wonderful and they used propofol so I was OUT!! UNCONSCIOUS!"
