They provided a prescription to prepare my GI tract for the colonoscopy which was much more pleasant than previous experiences. Arrived on-time at 10:15am and the office processed the paperwork quickly. Both Dr Patel and the nurse anesthetist visited with me beforehand, kindly responding to my questions by 10:45am. Procedure was over in 45 minutes and I was alert enough to get dressed and my wife picked me up at 11:45am.

"For 10+ years I've suffered with and no one could ever figure exactly what was going on. They could always find several things wrong... but no luck on connecting the dots! I've had multiple Dr's run countless tests to try and treat my symptoms, even went as far as exploratory surgery... with no help. I was referred to Dr Clark by one of my wonderful doctors after he did some research to try and find me some help. I went and seen Dr Clark one week, he ordered a bunch of tests after setting with me and going over a ton of information. Then when he called me back, he had a diagnosis! Dr Clark takes his time and listens! He is very thorough to make sure you are taken care of! I have referred him to several people already and will continue to do so! If you are in need of an amazing specialist with a wonderful staff, I HIGHLY recommend you go see him. Sincerely, Rachel Goodman"

"I saw Dr. Kevin McNamara six years ago and thought he was a thoughtful, kind, and thorough physician. When I needed to return to for routine care from the practice in April 2021 I was pleased to be able to request Dr. McNamara's services again. If this sort of thing (like having cameras in your nooks and crannies, or the diseases of digestive health in general) makes you nervous, his pleasant demeanor makes the unpleasant parts of GI healthcare just a little less unpleasant. When, according to doctor's orders, I have to return in five years, I hope to see Dr. McNamara again!"
