I think I can speak for most when saying that no one looks forward to their colonoscopy however Dr. Arndt makes the process from start to finish easy and stress free! I've had two other dr's in the past and Dr. Arndt is by far the best! He has the best bedside manner! His staff was outstanding! Would highly recommend! 10/10!
