"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."

"Dr Conkling diagnosed a not so common type of colitis and was later confirmed by a biopsy. He listens to your concerns and discusses different options of treatment. I highly recommend Dr Conkling for any upper or lower GI issues."

"Dr. Nightingale was great. He didn't have all my test results and advised we would reschedule appointment as soon as he did and reviewed them. Surgery not necessary at this time other test to run before that discussion is to be had. I really appreciate his straight forward answers."
