Dr. Nix was such a blessing to many of us in the health care field. He cared for his patients and never got upset if I had to call him after hours for one of his people. I remember him as a resident and he was so good to the residents in the nursing homes. He always had the nurses back when difficult patients were getting the best of us. I missed his visits after he retired and to his family I send much love and prayers. May he rest in peace until we see him again.
