Dr. O'Brien's surgical skills and comforting good nature were instrumental to my own successful treatment, some 18 years ago. At the end of our follow-up check-ups he would kick back and regale me and my wife with stories galore as he took a sincere interest in how we were faring. It was a privilege to have been his patient, and a student of his philosophy... that healing also relies on one's faith, family, and friends. My faith then and now includes belief in medicine and science, and in the goodness of others, especially that of Dr. John C. O'Brien III.
