Everyone was great and kind

No one looks forward to a colonoscopy. My experience could not have been better though…everyone from the nurses to Dr. Awtry were amazing. They treated me with absolute kindness and professionalism. Everyone I encountered knew what they were doing and needed to do. I was called personally by Dr. Awtry with my results and he thanked me for trusting him. I absolutely do trust him and will go back!
