Anthony H. Horan, M.D., a graduate of Dartmouth College, received his medical degree from Columbia's College of Physicians and Surgeons. He did his internship in internal medicine and one year of general surgical residency at St. Luke's Hospital in New York. After two years in the Air Force as a general surgeon, Horan returned to New York for a Urology Residency at Columbia Presbyterian Hospital. After seven years of solo private practice in New York City with an appointment as instructor at the New York Medical College, he left to be Associate Professor of Surgery (Urology) at Marshall University in West Virginia. That was a VA based medical school. This led, eventually, to his appointment as Associate Clinical Professor of Urology, UCSF, at the Fresno VA hospital. There, he gathered and published the crucial data that led to this book. After becoming fully vested, he did an additional 14 years of solo private practice in Wyoming and California. He fully retired in the spring of 2018.
