"Spoke with Dr Mills this past week via Telehealth. He had done an esophageal procedure for me a year ago. He was very kind and even checked on my condition while I was gone and across the country. He has now encouraged me again to follow through with his recommendation moving forward. He was patient even though a few other issues have come along in my physical life once again, and I had therefore decided I could not try to tackle anything anymore. He did not make me feel bad or guilty, I was apprehensive, as I never ignore a Dr’s orders. Dr Mills is a very calm & comfortable person to speak with, ask questions of, and I was 100% pleased that before, during & after my initial procedure he was right there with me, making sure that I was alright especially post procedure. Unfortunately there simply are not many Dr’s who make the time to give to their patients. Thank you, Dr Mills."
