There is no better anywhere as far as I'm concerned."

"This is my second colonoscopy with Dr. Arndt (10 years apart). I find him to be friendly, kind and competent. He makes a pre procedure call to explain everything and answer questions. I found the prep tolerable and not too harsh. The day of the procedure went smoothly. The staff is outstanding… professional, kind and reassuring. Dr. Arndt was wonderful as I have come to expect. I also appreciate receiving anesthesia from a CRNA (who was exceptional). The procedure went as expected and I was home in less than two hours. I received follow up communication from Dr. Arndt and the office staff. I am grateful to Dr. Arndt and the team. Thank you."

"Dr. Arndt is highly professional, available, friendly and personable, and he personally worked with me over the phone several times from the moment I called his office to schedule a procedure. Dr. Arndt and his wonderful staff worked with me as a new patient to expedit the procedure because I was experiencing problems and was anxious about it. A day before the procedure I was diagnosed with covid 19 and had to cancel. They graciously gave me room and time to recover but stayed in contact with me to make sure i knew that when I was ready they were ready for me. Procedure went without a hitch and he called me himself with the results several days before I expected them. Thank you"

"What can one say about a colonoscopy, right? Well, I can tell you this.. You'll never remember it (because of the anestesia😉).. But you will remember Dr Arndt and his top notch team of nurses and support staff. I never felt more comfortable about an "uncomfortable" procedure. The nurses explained everything fully so I never had a question about what was coming next. When you are being taken care of by the best, you know it because they're practiced enough at their job to be relaxed and THAT puts you at ease. I wish everyone is able to have an experience that's as quick and relaxed as I had. An overall enjoyable experience thanks to the people working with Dr Arndt."
